Presentation On a Complete CCTV System
Topics Types of CCTV solution Camera (Analog & IP) Storage Device Cables Other equipments Single line diagram of analog & IP CCTV
system Comparison of Analog & IP solution
INTRODUCING WITH DIFFERENT CCTV SOLUTIONS
Two types of solution available in market 960H analog1. Analog Solution
2. IP Solution
(Uses CCD image sensor with maximum resolution of 700TVL)
HD(Uses progressive scan CMOS image sensor which supports megapixel resolution up to 1080P)
(IP based advanced technology)
Camera Types In terms of
Solution Analog IP In terms of shape Dome Bullet Box PTZ Fish Eye Hidden
Analog Camera
Used for CCTV surveillance system for passing video data through traditional Coaxial cable
Different Analog Technologies
• 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 – Techpoint• Used by HIKVISION, AVTECH, POWERTECH
IP camera Advanced technology that
communicates through Computer network
Uses an individual IP for its own (Each camera)
PTZ (Pan-tilt-Zoom) is a special kind of camera (usually IP) for better zooming and 360 degree viewing angle
Observations…… Standards of price variations
(Camera): IP camera’s price is much higher than
Analog camera’s (PTZ is much more) IR distance (High IR range, High price) Lens (Variable lens has high price
than fixed lens) Resolution (As much the megapixel,
price got increased) Camera Body (Weatherproof,
Waterproof, Temperature resistivity etc)
Other facilities like PoE (For IP Cameras) WDR, DNR, AGC, BLC etc
Storage Device Digital Video Recorder (DVR)
Network Video Recorder (NVR)
(For IP camera’s) Hybrid(Supports both
Analog & IP) Tribrid (Supports analog,
HD-analog and IP)
Analog DVR
HD DVR
Observations…… Standards of price
variations (DVR & NVR) NVR is in higher price range
than DVR Channel (more channel, more
price) Maximum HDD capacity (High
HDD facility means rise in price)
Special facility like ONVIF, RAID etc
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- Cat-6 (For IP camera’s) Optical Fiber (For long distance connectivity)
Some other parts of Installation Analog Solution Camera adapter BNC connector Video Converter IP Solution Network Switch (with or without PoE, SFP) , Router Media converter Patch cord RJ-45 connector TJ Box SFP module
Typical Analog System
Typical IP System
Comparison of Analog & IP solutionDescription 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
Decisions….
Which Solution is better?
Which types of camera is better?
Decisions…. Solution For cost effective solution- Analog For larger area and long distance connectivity- IP For better control, reliability- IP
Camera For Inside area (wide) – Dome camera For outside area (long) – Bullet and
weatherproof For larger area control and zooming- PTZ
