This page is highlighting the difference between various CCTV video standards, technologies and resolutions.
This information is provided to guide our clients about CCTV System standards and to help them in choosing right product for them.
Analog CCTV or CVBS:
CVBS is acronym of Color Video, Blanking or Synchronization or Composite Video Base-band Signal, is an analog video transmission standard that uses single pair cable, usually co-axial cable. A Yellow colored RCA connector is used for its connection.
Maximum Resolution is D1 or 960H which is 720 x 576 pixels.
Supports real time video feed without delay. Requires low disk space for video monitoring.
Suitable for long distance video transmission over 300-Meter.
Cost is low. Ideal for Infrared Night Vision CCTV surveillance.
Remote monitoring on mobile phones is available.
AHD CCTV:
AHD is acronym of Analog High Definition, designed by Nextchip to utilize coaxial cable to transmit HD video.
Maximum supported video resolution is 720P (1280 x 720 pixels) and 1080P (1920 x 1080 pixels) HD video resolutions at 16:9 aspect ratio.
Cost is slightly high but affordable.
Best for Indoor video surveillance.
Remote monitoring on mobile phones is available.
HD-CVI CCTV:
HD-CVI is acronym of High Definition Composite Video Interface, developed by Dahua Security.

Cost is high.
Remote monitoring on mobile phones is available.
HD-SDI CCTV:
HDSDI is acronym of High-Definition Serial Digital Interface.
Uses coaxial cable for video transmission, its image quality is clear and loss-less.
No delay. Supported video resolution is 720P and 1080P.
Maximum distance it cam support is 100-Meter.

The above mentioned are the analog CCTV technologies, which offer HD video over coaxial cable. Their recorders (DVR) are fully digital devices which converts or encodes analog video signals to digital and having the ability to connect to IP network for remote access on PC and Phones.
IP is the fully digital video surveillance technology.
IP CCTV:
IP camera (also known as network cameras) system is fully digital video surveillance solution, which supports 1 Megapixel, 1.3-Megapixel, 2-Megapixel, 3-Megapixel, 4-Megapixel and 5-Megapixel plus video resolutions.
It requires Ethernet or UTP cabling or Wi-Fi service in case on wireless IP cameras.
It has delay in video transmission (in some cases), suitable for both long and short distance.
Cost is too high, large disk space is required for recording.
