3. Video Surveillance Systems
A video surveillance system monitors the behaviour , activities, or other changing information, usually, of people by means of electronic equipments for security purpose.
Modern security cameras use closed-circuit television (CCTV) technology.
CCTV is a system where signals are not publicly distributed but monitored for security purposes.
CCTV employs video cameras that transmit signals to a specific limited set of monitors.

4. MAIN PURPOSE
A surveillance camera is used in surveillance to monitor public or private areas that need to be monitored for security reasons.
SCOPE :
Prevention
Detection
Intervention

6. uses of cctv
CCTV is commonly used for a variety of purposes, including:
Building and ground security.
Traffic Monitoring
Overseeing locations that would be hazardous to a human.
for example, highly radioactive environment.
Obtaining a visual record of activities where it is necessary
to maintain proper security. For example, in banks, casinos, or
air ports,railway stations,hospitals,offices,exam centers.
Used in vehicles to detect theft or vandalism .

7. advantages Deters Crime:
The presence of CCTV camera system will reduce petty thefts and
vandalism in shops, malls and other public places.
Helps Maintain Records:
The images and videos captured by a CCTV camera system are often
recorded and stored into a database.
Protects Employees:
This is particularly helpful in customer service centers. The employees
providing customer service may sometimes be subjected to verbal
abuse or physical attack.CCTV camera system helps to identify such
instances and act immediately.
For Evidence in Lawsuits:
In legal cases of thefts and other forms of crime,videos and images
provided by the CCTV camera system can serve as a valid proof and
evidence against the defaulter

13. ANALOG CAMERA
Used for CCTV surveillance system for passing video data through traditional Coaxial cable.
When light passes through the Lens to the Sensor, it is converted to digital signals by Analog-Digital Converter.
Then processed by a built-in Digital Signal Processor.
The image is then converted back to analog by a Digital-Analog Converter so the image can be transmitted to DVR.

14. CONTd……… DIFFERENT ANALOG TECHNOLOGY
HD-CVI stands for High Definition Composite Video Interface
• The technology is introduced by Dahua
• Used by DAHUA, CP PLUS
HD-TVI stands for High Definition Transport Video Interface
• HD-TVI was developed by a USA company –Tech Point
• Used by HIKVISION, AVTECH,POWERTECH

15. IP CAMERA
A digital camera transmits video via network to a single central location for monitoring, recording, and video analysis. Advanced technology that communicates through Computer network. Uses an individual IP for its own (Each camera).

16. contd
A network camera mainly consists of a lens, an image sensor, an image processor, a video compression SoC(System on Chip) and an Ethernet chip that offers network connectivity for data transmission.
When light passes through the lens to the sensor, it is converted to digital signals and then processed by a built-in digital signal processor.
The processed video data is then compressed by a multimedia SoC to achieve a smaller data size for optimal transmission.
Finally, the video images are sent through the Internet to back-end devices to allow for viewing and storage.

17. RECORDer TYPES Digital Video Recorder (DVR)
Analog DVR
HD DVR
based on number of camera can be attached
-4channel
-8 channel
-16 channel
-32 channel
Network Video Recorder (NVR)-For IP camera
-With POE(Power Over Ethernet) ports
-Without POE(Power On Ethernet) ports
Hybrid(Supports both Analog &IP)
Tribrid (Supports analog, HD analog and IP)

18. POWER ADAPTER/SMPS DVR are supplied with a power supply.
Cameras do not come with a power supply.
A single camera needs 12V 1.5A.
We can use separate power (12V 1.5A)for each camera but it needs power outlet on each camera side.
To avoid this we can use a single power supply having more Ampere so that we can connect multiple cameras to it.

19. contd.......... 12V 5A –we can connect up to 4 cameras.
IP camera with PoE switch-
PoE switch will provide power to the camera through ethernet
cable.

20. Cables and connectors CABLES Power Cable
Used for power up the cameras, DVR, NVR.
Video Cable
-Co-axial Cables(For Analog Camera’s)
-Twisted Pair Cables- cat5/Cat-6 (For IP camera’s)
-Optical Fiber (For long distance connectivity)
VGI/HDMI/Coaxial cable for video out
Patch code for Ethernet connection
There is a specific cable that has been designed that has both a Coaxial cable and a power cable in one(3+1 cable).

21. CABLES WHAT CABLES YOU WILL NEED
Each camera that you want to connect to your DVR will physically need to be connected using a Coaxial cable that has a BNC connection..
The power cable is just like a extension lead that connects from your camera to the power outlet.
Patch code for Ethernet connection.

22. CONNECTORS BNC CONNECTOR DC PIN MALE RJ 45 a twist-lock feature where
The BNC connector provides
a twist-lock feature where
there is no chance of the cable
being dislodged from either
the DVR end or the Camera end.
DC PIN MALE
To connect power input to the camera.
RJ 45
Connecting Ethernet cable either from
IP camera to NVR/POE switch in IP system
DVR to Switch/Modem in analog system.

25. Contnd………….

26. Contd……….
An analoge camera transmits analog video via coaxial cable to a single central location for monitoring , recording, and video analysis.
Analog CCTV systems connect to a DVR (digital video recorder)using coax cables and BNC connectors. •
power cable connects the analog camera to power supply.
DVR is responsible for image encoding and storing.
The length for coaxial cable between the DVR and the camera may be over 700m.
The signal is sent to the DVR where it is recorded on a hard disk.
The DVR is capable of transmitting the video signal live on a monitor connected to the DVR

27. contd.......... Characteristics: Low initial investment.
Wide-spread compatibility
Analog cameras tend to handle low-light situations better than IP cameras on average

28. IP SYSTEM

29. Contd………….
A digital camera transmits digital video via network to a single central location for monitoring, recording, and video analysis.
IP CCTV requires UTP cable i.e. Cat 5 or Cat 6 cable.
UTP cable connects the IP camera to the PoE switch (Power of Ethernet) Maximum distance of 100m.
The PoE switch will power up the camera.
The camera itself compresses and encodes the digital signal and then sends it to the NVR via IP (Internet Protocol).
The NVR then records or copies the actual video file from the camera and as there is no conversion between digital and analogue and back there is no loss in picture quality.
Instead of an NVR a server computer may be used with management software for detailed surveillance.

30. contd........... Characteristics:
Superior image quality-high resolution of the captured
images
Cost-effectiveness
Remote accessibility-cameras can be viewed from any
computer any where in the world
Easy, reliable installation
Flexibility: It can be moved anywhere in the IP network
Encryption and authentication : transmission of data is
done through encryption
PoE : Cameras can operate without additional power. PoE
protocol is used to feed them through internet cable
