Our client received the new purchased units,they would like to know what the field depth is on the CMOS camera? Can you advise?

The device's built-in CMOS camera is like other normal analogue CCTV camera that it can be used to take a picture ,and also output  a standard and non-compress analog video signal  to the LCD monitor or DVR via BNC connector for the video surveillance purpose.

Its specification is "NTSC-M"  with 525 lines ,and 29.97 frame rate.(712x486 pixel)  And it did not support the field depth feature.
