3. WHAT IS CCTV SYSTEM?
Closed-circuit television, also
known as video surveillance, is
the use of video cameras to
transmit a signal to a specific
place ,on a set of monitor.

4. TYPE OF CCTV SOLUTION

9. CABLES
• Power Cable
Used for power up the cameras, DVR, NVR (usually two core)
• Video Cable
Co-axial cables- RG-6, RG-11, or RG-59 (For Analog camera’s)
Twisted Pair cables ( IP camera’s)
Optical Fiber (for long distance connectivity )

10. CAMERA TYPES
 In terms of Solution
• Analog
• IP
 In terms of shape
• Dome
• Bullet
• Box
• PTZ
• Fish Eye
• Hidden

11. ANALOG CAMERA (WIRED CAMERA)
• Used for CCTV surveillance system for passing
video data through traditional Coaxial cables

12. IP CAMERA (WIRELESS CAMERA)
• Advanced technology that communicates through computer
network
• Used an individual IP for it’s own {Each camera)
• PTZ (Pan Tilt Zoom) is a special Kind of camera ( usually IP }
for better zooming and 360 degree viewing angle

13. COMPARISON OF ANALOG & IP SOLUTION
Description Analog Solution IP Solution
Video Quality Good Much better than analog
Individual camera
Viewing
Not possible Possible through individual
IP
POE facility Not available Available
Installation cost Comparably low High
Installation Comparably easy Complex
Long distance
connectivity
Not reliable Reliable
