Voltage from a CCTV camera
--94eb2c1cd0e852777c055eacb7a6
Content-Type: text/plain; charset="UTF-8"
I'm wondering what voltage I should expect on the video signal from a
conventional (i.e. not IP) cctv camera. The cameras all have a 12v supply
and the voltages across the pin and ground at the DVR BNC end range around
1.18, 1.5, 1.7, 1.2 and 2.12v.
I thought video was +/-1v either side of 0v.
I find it a little odd that all are between 1v and 2v, except one, at
2.12v.
Is 2.12v likely to be an issue?
Thanks,
Tim.
