Hi,

Thanks for your reply.  Unfortunately, mine is not a "good" camera (it was bundled with the video recorder) and has only a BNC (CVBS) and power connectors on a long cable.  The User Interface offers only CVBS controls (brightness, contrast, colour, tint) and a crude digital zoom.

I'd be happy to "open it up" and disconnect the LEDs (or modify the relay), but I can't find any screws to turn. I even made a large "washer" to block the IR, but the heat and scatter upset the picture quality (and of course couldn't save any power).    

Cheers,  Alan.

Hi,

I'm afraid that lightning control is only possible with IP cameras. Cheap CCTV security cameras probably do not.
I think it would be possible to buy a camera without an IR LED.

But it is also the case that the typical security cameras are still slightly different from the weather cameras.
At least the weather camera is heading to the sky, motion detection is undesirable, recording is useless, and
IR LEDs are useless. They also do not have any security against the attack. On the other hand, it should
have an FTP protocol (therefore it should be digital = IP). But otherwise the technique is almost the same ...
