ABSTRACT
Pre-installation calculations and assessments are essential for the installation of a video
surveillance system. At KARAYES GROUP, the existing pre-installation calculations were
done manually which often lack precision prompting the need for refined methodologies. This
internship report presents the findings and experiences gained during the five months of
internship at KARAYES GROUP, focusing on a case study at Refresh and Relax Beauty Center
in Yaoundé. The primary aim centered on the installation of three Smart IP PTZ(Pan-Tilt-Zoom)
cameras, with focus on the pre-installation calculations and assessments conducted using IP
video system design tool, a 3D design software that helps in the planning of security cameras
placement. The report provides an overview of the project, discusses the methodology
employed, and presents the results obtained. The findings highlight the importance of accurate
pre-installation calculations and assessments in ensuring the successful implementation of
video surveillance systems. The proposed solution helps to enhance the accuracy and the
efficiency of the system. Through simulation, this study identifies critical parameters
influencing the system’s performance such as network bandwidth, storage capacity, camera
placement validating the effectiveness of the proposed approach and obtaining a correct field
of view. In conclusion, the integration of IP video system design tool offers significant benefits
not only for the installation of video surveillance systems, but also makes the company more
professional and differentiates itself from many other companies involved in video surveillance
system installations.

Keywords: Video surveillance system, Network bandwidth, Storage capacity, IP video system

GENERAL INTRODUCTION
Video surveillance system is a network of cameras, recorders and monitors/display units.
Cameras can be analog or digital with various features to explore, such as resolution, frame
rate, colour type, and more. People use this system to keep places safe, for security or to watch
over things. It is not just randomly putting up cameras, it is about smart planning and careful
calculations to decide where each camera should go. While working at KARAYES GROUP,
my focus was to study Network and Security systems installations mostly based on video
surveillance systems. We decided to focus on the planning part “PRE-INSTALLATION
CALCULATIONS AND ASSESSMENTS FOR A VIDEO SURVEILLANCE SYSTEM”. To
deepen our understanding of this aspect, we proposed the utilization of a software called IP
video system design tool, a 3D design software that helps in the planning of security cameras
installations. This software includes CCTV storage, bandwidth and field of view calculators,
lens focal length and pixel density calculator. Taking as case study the installation of Smart IP
cameras in Refresh and Relax Beauty Center in Yaoundé.

CHAPTER TWO: OVERALL INTERNSHIP EXPERIENCE

2.1 Joining the Company


Securing an internship proved challenging despite the less stringent selection criteria for the
unpaid position. Armed with official school documents, a comprehensive CV, and a
handwritten application, I applied to six companies in Douala, on July 5th, 2023. Fortunately, I
received an offer from KARAYES GROUP and commenced work on July 18th, 2023. My
supervisor warmly welcomed me and provided an overview of the projects and tasks I would
be involved throughout my internship.

2.2 Designated Work Section within the Company


During the five months I spent at KARAYES GROUP, I was privileged to work in the field
with the technicians of the company. Some of the tasks performed were:
- Full installation of internet connection using Starlink in a Call Center in Douala and in a
mayor’s house in Bafoussam.
- Video surveillance system installation in clients’ houses and shops.
- Fingerprint Access Control Installation.
- Configuration of repeaters, routers and Nanostation-M2.
- Installation of electrical bulbs, power and network outlets.

2.3 Execution of Tasks and Associated Procedures


I took a methodical approach, doing thorough research, working closely with my team, and
asking questions to my supervisor. In the next part, I will discuss about some of the tasks I did
from July to December.

2.3.1 Installation of Security Cameras


During the first month, I mainly worked on installing security cameras in clients’ homes. My
main tasks were:
i. Crimping the Ethernet cables
In order to crimp an Ethernet cable, we need to know the order of the colour code. The colour
code according to the T-568A and T-568B standards is shown in Figure 2.1 below:

Figure 2.1: Ethernet Cable Colour [3]

6
INTERNSHIP REPORT ON PRE-INSTALLATION CALCULATIONS AND ASSESSMENTS FOR A VIDEO SURVEILLANCE SYSTEM

The procedures I used in performing the crimping of the Ethernet cables were;
- Started by stripping the cable to remove the outer jacket. Untwisted and arrange the wires
according to the colour code which can be T568B or T568A standard. But I used the T568B
standard. I trimmed the wire using a wire cutter to my desired length and inserted the wires in
the RJ45 connector by arranging them according to the color code. Figure 2.2 shows how the
wires were inserted according to the T568B standard: -

Figure 2.2: Insertion of the wires in the RJ45 connector using T568B standard [4]

- Inserted the wires into the connector. Then inserted the connector with the wires inside the 8P8C
slot of the crimp tool, crimped by applying enough pressure. Repeated the same procedure for
the other end of the cable.
- Tested the crimped Ethernet cable using a cable tester and it showed pass (all the 8 wires are
making connection since all the LEDs blinked in green).
ii. Connection of the HDMI cable from the DVR recorder to the monitor for camera viewing
and researching on how to set up and configure a repeater.

2.3.2 Set up and Configuration of a repeater:


A repeater is a device that regenerates and amplifies signals as it passes through the network.
To configure the repeater, here are the procedures I followed; -
- Plugged the repeater into a power outlet near the available router and waited for the wireless
LED to turn on. Went on the Wi-Fi settings of the computer and connected to the repeater.
Opened a browser, entered http://tplinkrepeater.net in the address bar. Logged in using “admin”
for both username and password, and then created a new username and password. Waited for
the repeater to detect networks, selected the house router’s network, entered the Wi-Fi
password, and clicked “next”.
- Created a new network SSID for the repeater, different from the router, and clicked “next”.
Verified the wireless settings and clicked “finish”, triggering the repeater to reboot. To finalize,
unplugged it from the power outlet and plugged it into another power outlet (installed by my
technical supervisor) that was mid-way between the router and the area of the house where the
signal was weak.

INTERNSHIP REPORT ON PRE-INSTALLATION CALCULATIONS AND ASSESSMENTS FOR A VIDEO SURVEILLANCE SYSTEM

2.3.3 Configuration of an Ubiquiti Nanostation-M2 and a TP-Link


Router as an Access point.
The configuration of NSM2 was done in Bafoussam at a Mayor’s house and that of a router
was done in a new call center in Douala.

▪ Configuration of an Ubiquiti NSM2 as an access point


An Ubiquiti Nanostation-M2 (NSM2) is an outdoor wireless access point. It is a point-to-point
and point-to-multipoint wireless solution. To configure the NSM2, I observed another NSM2
being configured in another work field and was asked to configure it on a different day. Here
are the steps I followed; -

- Powered on the NSM2 using the provided power adapter and connected it to my computer
using an Ethernet cable, configured my computer’s network settings. Opened my web browser,
entered https://192.168.1.20. (the IP address on the NSM2) to access the configuration page,
used “ubnt” as the username and password, selected the country (Cameroon), accepted the
terms and logged in. Changed the user name and password.

Configuration in the Wireless tab: Configured the wireless tab, so that the NSM2 acts as a Wi-
Fi Access Point, changing the channel width to 20MHz and turned off the airMAX protocol.
Entered the SSID of the router’s Wi-Fi in the SSID field and set the wireless security setting to
WPA2 security and inserted the Wi-Fi’s Password.
For network settings: Assigned an IP address to the Nanostation-M2, for example the router’s
IP address was 192.168.1.1, assigned an IP address ,192.168.1.100 to the Nanostation-M2 (still
in the same subnet as my network but does not conflict with other devices). With a subnet mask
of 255.255.255.0 and set the NSM2 to Bridge mode (as we wanted the Starlink’s router to
continue controlling the network), assigning the Default Gateway and DNS IP addresses to the
router’s address (192.168.1.1). Clicked on apply, then saved changes and later on, verified the
configurations and performed a speedtest.
Applications of the Nanostation-M2
i. Connect two remote locations on the one network.
ii. Share internet connection between buildings and remote sites.
iii. The Ubiquiti NanoStation-M2 can be used to create a point-to-point or point-to-multipoint
wireless bridge, allowing devices to connect wirelessly over long distances.

▪ Setup and Configuration of a TP-Link router

8
INTERNSHIP REPORT ON PRE-INSTALLATION CALCULATIONS AND ASSESSMENTS FOR A VIDEO SURVEILLANCE SYSTEM

A router is a networking device that forwards data packets between computer networks. To set
up the router as an access point the following steps were done: Connected the router to my PC
using an Ethernet cable, accessed the router’s interface by typing its IP address (198.168.1.1)
into a web browser, and logged in using “admin” as both the username and password. Then I
disabled the DHCP, changed the router’s IP address to an available one outside the DHCP range
but within the same subnet as connected devices, and saved the settings. Finally, I entered the
Wi-Fi’s name and password from Starlink, renamed the router, assigned a new password for
internet access, updated all changes, restarted the router, and successfully tested the internet
access.

Figure 2.3: Configuration of an Ubiquiti Nanostation M2 and a Router as access point

2.3.4 Installation of a Network and Power Outlets


In a new Call center in Makepe, Douala, I was assigned to install some network and power
outlets.

▪ Installation of network outlets:


A network outlet is a physical socket where network cables can be connected to establish
network connectivity. It works as a two-way channel, facilitating both sending and receiving
data. Below are the procedures I used; -
- Trimmed the Cat.6 network cable to the desired length using a cable cutter. Then, stripped a
small section of the cable’s outer covering and tightly secure the wires to the mounting plate
of the network outlet using a screwdriver.
- Followed the color code on the circuit board of the network outlet to connect the individual
wires in the correct sequence.
- Finally, placed the installed network outlet in the cable tray on the floor and handle the wiring
of an electrical outlet next to it.

▪ Power outlets installation:


A power outlet is a device used to provide electrical power to devices. As my technical
supervisor had already wired the other power sockets, I focused on preparing the cable route

for the new socket location by extending a new cable from the supply socket. After threading
the cable end through the mounting boxes at both the supply and new socket locations, matched
the cores from both cables: Live(L) with Live, Neutral(N) with Neutral and connected them to
the terminals on the faceplate. As shown in Figure 2.4:

2.3.5 Installation and Configuration of Starlink


Starlink is a satellite internet constellation being constructed by SpaceX (Space Exploration
technology), the aerospace company founded by Elon Musk. The goal of the Starlink project is
to provide high-speed, low-latency internet access to underserved and remote areas around the
world [3]. Starlink kit consists of the following equipment: -

i. Starlink Satellite Dish: The satellite dish is the main piece of equipment in the Starlink
system. It is used to communicate with the Starlink satellites in orbit, providing internet
connectivity to users on the ground.
ii. Starlink Router: The Starlink router is used to create a Wi-Fi network in the user's home or
business, allowing devices to connect to the internet via the Starlink satellite dish.
iii. Power Supply: The power supply is used to provide electricity to the Starlink satellite dish
and router, ensuring that the system remains operational.
iv. Mounting Hardware: Mounting hardware is used to securely attach the Starlink satellite
dish to a roof, wall, or other structure, allowing it to point towards the satellites in orbit.
v. Ethernet Cable: An Ethernet cable is used to connect the Starlink router to a computer,
smart TV, or other device, providing a wired internet connection.
vi. App: The Starlink app is used to set up and manage the Starlink system, allowing users to
monitor internet usage, troubleshoot connectivity issues, and adjust network settings. Figure

i. Installed the Starlink mobile app. Opened the app, with two options presented: find an
installation location or start setup.
ii. Located installation site, scanned the sky and received a positive result stating. “This is a
great place for your Starlink.”
iii. Set up the Starlink by mounting the base, connected the Starlink cable to the device, slotted
the Starlink into the base, and powered on the router using the AC cable port. In the app,
clicked “next” and selected “OPEN SETTINGS” to connect to the Starlink’s router.
Established the connection and accessed Wi-Fi settings and connected to Starlink, setting up
a password. Successfully connected to the Starlink’s Wi-Fi and performed a speed test to
ensure a reliable connection. Figure 2.6 below shows the installation result and testing of the
internet speed with the workers in a call center in Douala.

Figure 2.6: Starlink installation Project

2.4 Performance When Accomplishing Tasks


Personally, I did good because I quickly connected with the technicians and got involved in
different fields to gain more knowledge. The tasks at the office were impressive since I initially
had no knowledge about cameras, cables, costs, or report writing. I was not super-fast, but I

11
INTERNSHIP REPORT ON PRE-INSTALLATION CALCULATIONS AND ASSESSMENTS FOR A VIDEO SURVEILLANCE SYSTEM

handled tasks calmly, and tried my best in analysis and troubleshooting. I also had positive
feedbacks and encouragement from my professional supervisor. Overall, in the last five months,
I performed well, gaining practical knowledge that links with certain things I learned in class
over the past three years. This experience taught me a lot and I hope to learn more in the future.

2.5 Challenges Faced and Measures Taken to Handle the


Challenges
Undoubtedly, I encountered challenges during my internship. Challenges such as: -
i. Inadequate knowledge in some fields: To handle this challenge, I engaged in self-study using
my browser and YouTube to make research and I also asked for guidance from the technicians
to bridge the knowledge gap.
ii. Feeling underutilized: The measure I took to handle this was to initiate communication with
my professional supervisor. Also volunteered for any task the company was involved in.
iii. Coping with unfamiliar office culture: I had to integrate into the workplace culture, like
respecting the rules of the company, ensuring the cleanliness every day and the way of
addressing the workers.
iv. Difficulties in knowing certain devices and equipment in English: I invested time in
learning the names of the equipment in English as I did the internship in a francophone
company.
v. How to do the work: To handle this challenge, I asked for guidance from the team
members and watch different videos and lectures on how the work is being done.

2.6 Extra-Curricular Activities


Beyond my core responsibilities, I actively participated in extra-curricular activities organized
by the company. Extra-Curricular Activities included:

i. Writing of reports after every work done during the day: By the end of each day I had
to submit report on the tasks accomplished in the company’s WhatsApp group.
ii. Price research online and bill preparation for the clients: Each time we had to do an
installation and the client wanted us to buy the equipment, my supervisor will ask me to look
for the prices online and write them down.
iii. Cleaning of the office: Since I was the only girl in the team, I took care of cleaning the
office every morning. I had to ensure a clean and organized environment for our clients and
the workers.
iv. Refreshments: After every hard task, we were given food and drinks.

CHAPTER THREE: INTERNSHIP PROJECT ON PRE-


INSTALLATION CALCULATIONS AND ASSESSMENTS FOR
A VIDEO SURVEILLANCE SYSTEM

3.1 Introduction
Video surveillance is the use of security cameras to monitor and record activities in a specific
area or location for security, safety or monitoring purposes. Security cameras capture live
footage, which can be viewed in real-time or recorded for later review. Figure 3.1 below shows
the structure of video surveillance system [4].

Figure 3.1: Video surveillance System Structure


What are Pre-installation calculations and Assessments for a video surveillance system?
Pre-installation calculations and assessments for a video surveillance system are the different
steps that have to be taken before the installation of a video surveillance system. Before setting
up a video surveillance system, it is really important to plan and assess everything carefully.
This makes sure that, the system works well in the specific place where it is going to be used.
By doing this planning and assessment ahead of time, we can find and fix any potential
problems early on, which makes the whole process of setting up the system much smoother and
more effective. It is not just about placing cameras randomly but a smart way to do that.

3.1.1 The Working Principle of Video Surveillance System.


According to Figure 3.1 above, the Video surveillance system works as described below:
- Front-end (Camera): The camera captures video footage of the monitored area and sends
the video signal to a recording device. These cameras can either be fixed, dome, bullet or
Pan-Tilt-Zoom (PTZ) cameras.
- Transmission: The video signal captured by the camera is transmitted over a network or

13
INTERNSHIP REPORT ON PRE-INSTALLATION CALCULATIONS AND ASSESSMENTS FOR A VIDEO SURVEILLANCE SYSTEM

cable to the recording device or monitoring station. This can be done using wired
connections (such as Ethernet or coaxial cables) or wireless connections (such as Wi-Fi,
cellular networks).
- Recording and Searching: Mainly include back-end products. The video signal is recorded
and stored on a recording device, such as a Digital Video Recorder (DVR) or Network Video
Recorder (NVR). This allows users to access and review the recorded footage at a later time.
We also can have storage server as storage device and a management platform.
- Decoder: It converts the compressed video data into a format that can be displayed on a
monitor or streamed over networks for remote viewing.
- Display: The recorded video footage can be monitored in real-time by security personnel
or remotely by authorized users using a computer, smartphone, or other device with internet
access.

3.1.2 Types of Cameras that make up Video Surveillance System


When it comes to video surveillance cameras, there are two basic types of cameras. The two
types of surveillance cameras are analog and digital.

1. Analog Camera:
In an analog camera system, the camera captures an analog signal. This signal is transferred
through a coaxial cable to the DVR (Digital Video Recorder). The DVR converts the analog
signal to a digital signal, compresses it and stores it on a hard drive within the DVR. The
footage can be viewed on monitors attached to the DVR using either an HDMI (High
Definition Multimedia Interface) or VGA (Video Graphics Array) cable. Also, the DVR can
be set up to transmit the video footage over the internet for remote viewing and when this is
done with an analog system, all of the cameras’ signals are sent as one stream using one IP
address. Figure 3.2 below shows an example of an analog camera called dome camera

Figure 3.2: Analog Camera


2. IP Camera:
In IP (Internet Protocol) camera system, each camera captures an analog signal, which is then
converted to a digital signal within the camera itself. The digital signal is transmitted through
the monitoring system using Ethernet cables (like Cat.5 or Cat.6) or Wi-Fi or Cellular
network. Unlike analog systems with DVRs, IP cameras are either centralized (the need of a
Network Video Recorder) or decentralized (no need for NVR and the footage can be recorded

14
INTERNSHIP REPORT ON PRE-INSTALLATION CALCULATIONS AND ASSESSMENTS FOR A VIDEO SURVEILLANCE SYSTEM

and managed from any local or remote storage media). Figure 3.3 below shows an example
of an IP camera called dome IP camera.

3.3 Literature Review


Video surveillance systems play a crucial role in enhancing security and monitoring in various
environments, including public spaces, commercial establishments, and residential areas
[5].An effective security technique should have the ability to specify areas of risks and
delineate standards for decreasing undesired incidents [6].According to Wikis(2015),there is
no system that can ensure complete coverage, and every system has its own strong and weak
points [7].Focusing on security systems of multiple surveillance cameras, the cameras may
leave small uncovered areas which might be a target for suspicious activities. The existing pre-
installation calculations were done manually which often lack precision and increase the
possibility of not covering some important areas which are located under the field of view of
the camera. This case study brings up a way to reduce this problem by using a 3D IP video
system design tool. This literature review explores key considerations in pre-installation
assessment, encompassing camera placement, environmental factors, privacy concerns, and
ethical considerations.

3.3.1 Camera Placement and Coverage


Determining the ideal placement of surveillance cameras is crucial for effective coverage.
Before installing a video surveillance system, it is essential to conduct a thorough site survey
to determine the optimal camera placements, coverage areas, field of view and identify
vulnerable areas [8]. Studies have investigated different models to assess camera coverage,
often utilizing simulation tools [9].

3.3.2 Bandwidth and Storage Requirements


Another critical consideration is estimating the network bandwidth and storage requirements
for the surveillance system. The consideration of the network bandwidth and storage
requirements when designing a video surveillance system is very important to ensure efficient
data transmission and recording [10].

3.3.3 Environmental Factors


Understanding environmental factors is critical for assessing video surveillance system
performance [11]. Factors such as camera mounting height, viewing angles, and
environmental conditions (for example: weather, lighting, obstructions) should be considered
during the pre-installation assessment. Considering the use of indoors or outdoors cameras
(which can be waterproof, resistant to high temperatures or other related factors).

16
INTERNSHIP REPORT ON PRE-INSTALLATION CALCULATIONS AND ASSESSMENTS FOR A VIDEO SURVEILLANCE SYSTEM

3.3.4 Privacy Concerns and Ethical Considerations.


Pre-installation assessments should also address privacy and ethical considerations [10].Many
surveillance systems operate without the explicit concern of individuals being recorded so we
need to take privacy into consideration.
To conclude, pre-installation calculations and assessments for video surveillance systems
involve considerations such as camera placement, coverage, bandwidth, storage requirements,
environmental factors, privacy and ethical considerations. A comprehensive understanding of
these aspects is crucial for designing an effective video surveillance system.

3.4 Problem Statement and Objectives


3.4.1 Problem Statement
While working at KARAYES GROUP, the existing pre-installation calculations were done
manually which often lack precision and increase the possibility of not covering some important
areas which can be located under the field of view of the camera as shown in Figure 3.6 below:

Figure 3.6: Invisible area under the field of view of the camera
Also, no actual calculations were done concerning the storage capacity and the network
bandwidth required for the video surveillance system.

3.4.2 Objectives:
▪ Main Objective:
The main objective of this work is to use a software called IP Video System Design Tool to
perform the pre-installation calculations and assessments for the Video surveillance system.
▪ Specific Objective:
- To perform a site survey of the beauty center, to know the requirements of the client, collect
enough data for the implementation of the design and choose the appropriate cameras for the
system.
- To perform the calculations manually, compare with the results obtained using the software.

17

3.5 Case Study


Since we had to install three Smart IP PTZ(Pan-Tilt-Zoom) cameras in Refresh and Relax
beauty Center opposite Mario college in Yaoundé, I decided to take this project as a case study.
A Smart IP PTZ(Pan-Tilt-Zoom) camera was chosen for the installation due to its ability to send
and receive footage over the internet, the monitoring of large areas. Figure 3.7 shows how the
connection of this IP PTZ camera was done [13]: -

Figure 3.7: Schematic Diagram of the Smart IP PTZ camera

3.5.1 Methodology
In order to perform this task, I followed the methods below
- Define Objectives and Requirements.
- Site Survey.
- Selection of Cameras.
- Design of the Beauty Center using IP Video System Design Tool software.
- Installation planning.
- Video surveillance system installation and testing.
- Training the users on how to use the ICEE app for remote viewing.

3.5.2 System Design


Clear requirements, a comprehensive site survey, and proper equipment selection and
installation must all be considered when designing a video surveillance system. To perform
this task, the first thing to do was:
- Selection of the appropriate Camera: For this installation we chose a Smart IP PTZ camera
since it has all the features of the client’s expectation
- Camera Placement and Calculation of field of view (FOV): The client expressed the need
to monitor both indoor and outdoor areas. As per her specifications one camera was
positioned in the stylist room, another in the reception room, and the third outside the area
designated for drinks and food sales. The field of view was chosen using the IP video system
design tool, as shown in simulation in Figure 3.8. For the installation of three smart IP PTZ

18

From the calculations above, we bought three memory cards of 256GB for the recording of
the surveillance camera system for about ten consecutive days.

3.5.3 Simulation
The simulation below shows the design of the beauty Center done and how the cameras were
positioned for large coverage area on Figure 3.8. The DVR’s (Digital Video Recorder) output
in Figure 3.9, shows the view of the beauty center and how it will be displayed in the smart
phone. Figure 3.10 shows the network bandwidth and storage calculations performed by the
software considering the cameras’ specifications like resolution, frame per seconds and the
number of days for the recording (the number of days allocated,10days consecutively).

3.6.2 Power Consumption


The power consumption depends on the type of camera you choose to install.

- Total power consumption (in watts) = Power consumption of PTZ camera + power
consumption of network equipment.
- Power =Voltage * Current
- Energy Used per day= Power*Hours of use per day
- Energy used per month=Energy used per day * 30
The data below are from the camera and router specification manual as explained above
in the system design.
Table 3.2: The Estimated Power Consumption

Item Quantity Power rating of Energy used per Energy used


one item/W day/KWh per month/
Smart IP 03 12*2=24 (3*24) *24=1.728 51.84KWh

Router 01 12*1=12 12*24=0.288 8.64KWh
Total Power 36 2.016 60.48KWh
From the above power consumption, assuming that 1KWh in Cameroon cost 50frs.It means
that this client will spend about:

60.48KWh*50 = 3024 FCFA per month.

3.7 Video Surveillance System Installation Procedure:


During the installation, my technical supervisor offered guidance, but I executed most of the
tasks independently like:
-The configuration of the router, renamed it to “Refresh and Relax Beauty center”, and set a
new password.
- Downloaded the ICSEE app (the monitoring security software).
- Connected the cameras to Wi-Fi and each camera was named and configurations saved.
- Ensured internet connectivity through the Camtel bundle in the router and conducted a
speedtest. Mounted the cameras with the assistance of the supervisor, drilling holes, connecting
power sources, and securing cameras using screws and cable clips. This comprehensive setup
was validated by the supervisor, and later, users were trained on how to use the App for remote
viewing.
▪ Discussion and Installation Results:
The IP PTZ cameras installed was a non-centralized system (no need of the Network
Video Recorder or hard drive) since it has the ability to take internal memory card as a

22
INTERNSHIP REPORT ON PRE-INSTALLATION CALCULATIONS AND ASSESSMENTS FOR A VIDEO SURVEILLANCE SYSTEM

storage facility. The cameras were displayed and we could see the different videos from
the ICSEE app as shown in Figure 3.11 below: -

Figure 3.11: Installation Results and View on the App

▪ Conclusion
Completing the video surveillance system installation for Refresh and Relax Beauty Center was
a win for me. With this software, the company will be able to proposed a detail documented
design for the system before the video surveillance system installation showing the client: -

- Why cameras should be placed in this position.


- Why they need a certain number of cameras, the amount of storage and network bandwidth
required.
Careful pre-planning not only streamlined the installation process, but offers several advantages
like optimal camera placement, cost efficiency and time savings as everything is already being
carefully pre-planned. The software is very user friendly.

Using this software, there is no need for guesswork anymore. We can see that, from the manual
calculations and the calculations performed by the software, there’s a difference of about 20%
due to the different assumptions made manually therefore, showing the accuracy of this tool as
everything is being generated by the software during the calculations

The disadvantage of this tool is that, it can be expensive for small companies.
