Question about JVC Tk-C920u 1/3" CCD Super Lo-Lux Hi-Res 535tvl Color Security Camera
When I power my camera with a 24vac supply the image is extremely noisy but when powered via 12vdc it is clear. Any suggestions
Based on your post/description, your power supply is faulty.
1. It your 24VAC adapter/power supply is the original one that came with the camera, then most likely a component failure inside. More often it is the filter capacitor.
2. If it is a replacement, then possibly the ratings are not compatible with the camera, specifically the current or power (Amps or Watts).
3. In some instances the built-in regulator might be shot since your source is 24 but your load rewuires only 12.
Hope this be of some help/idea. Post back how things turned out or should you need additional information.
Good luck and kind regards.

Enter this command to turn on the Bell, keypad
sounder and keypad LEDs for 2 seconds. The
battery is tested during a Bell Test, and automatically
every *24 hours to ensure proper battery
operation under load. The Alarm output
requires a battery in order to supply the specified
output. If the battery cannot sustain the load, a
low battery indication will be displayed. A battery
test is also performed on power-up after a 3
if the battery fails test replace it and try again.
Assuming no programming changes were made to the zone types that would diable the bell output. if this does not help, time for an upgrade. : ( GL
