Analog Performance of IP Cameras

[kamal3965 0]

Is there anything called "Analog performance of IP Camera". In some of the tenders, which I have browsed on the internet, they mention 520 TVL for the same. I believe IP cameras are measured in terms of Pixels and not TVL(TV Lines)

Some IP cameras have analog resolution rather than high def. Just cause they're IP, does not mean they are high def.

Thanks, for the info.

You can measure TVL on any camera. Getting an absolute TVL result is tricky, but getting a relative TVL result to compare between multiple cameras is fairly easy.

 

Typically, 1 and 2MP cams will run somewhere on the order of 800-1200 TVL, but like with analog, it depends on many things.

 

- Sensor resolution

- Lens quality

- Software processing and compression

- Aside from the camera, there's DVR compression as well

 

Generally, when you see an analog camera that says 600 tvl or whatever, they are referring to the capability of the sensor and processing chip, and don't take into account the lens quality, which is usually poor on inexpensive cameras.

 

Marketing and difficulty of measuring actual TVL has made this a meaningless number.
