In Australia, NTSC camera work on 50hz 24v supply or not??

In australia, looking at getting a box IP CCTV Camera that is NTSC and the specs say it runs on 24V AC 60Hz and a PAL camera runs on 50Hz.

if I run this NTSC camera on 24v at 50Hz will there be any issues with the image stability or anything??

this NTSC camera also runs on 12vDC, if there is an issue with the 50Hz AC supply would it run ok on the DC power? will it also affect any image quality running on DC compared to AC??

is there anything else I need to be aware of?

Wozzza,

DC has no effect because it just drives camera chip and system.

AC mismatch can cause some problems because fluorescent lamps on and off at 50Hz. You would get some noisy(wavy) video.

so I can run this system on 12vDC with no issues you think?

Yes. No AC is needed for operating DVR and Camera.

They need Adaptor (AC to DC) for AC power source

If camera is set for NTSC (set for 60Hz) and your fluorescent lamp ons and offs at

50 Hz, the brightness level of video would keep fluctuating and appearing as noisy video.
