Excellent. Thanks guys. I did double check and the cameras are DC. Old Supercircuits cameras/system. Now I'm trying to track down a compatible HDD for the DVR...

Thanks. If frequency isn't an issue with DC then I should be good.

" then i think it would be better than having power converters and addaptors you update your power supply this type is duel voltage and is 50/60Hz auto switch around £20 and you can use it anywere in the world. " So voltage frequency does not affect CCTV cameras? My thought is if an NTSC camera functions at 30fps and the 'fps' part of that is calculated off of the voltage frequency then changing that frequency to 50Hz would change the resulting image.

does your dvr have a plug in power supply or is it built into the dvr. The DVR has an external power supply akin to that of a laptop.

What sort of issues would effect a full US NTSC system that was packed up and shipped to 240VAC/50Hz country? The monitor is auto switching. The DVR is on a auto switching power block. The cameras are 24VDC. I imagine the system would work but I'm concerned the 50Hz could have an effect on the cameras but I'm also thinking since the cameras were manufactured overseas it wouldn't be a problem. Thoughts?
