I just got two used ADC v724 cameras. The prior owners cut the camera tails (yes, I know it shouldn’t have been done). Where can I find a replacement female barrel cord that works with these? Or what other options do I have?
Check an online electronics retailer like Mouser for barrel plugs, or Amazon may have a kit with multiple sizes though it will generally be more expensive there. Though if the camera tail is already cut you could splice directly onto the wires of the plug in power supply it comes with.
I know it is not what you are looking for but I would always strongly recommend returning the cameras if they were not described this way. That kind of installation of the equipment often results in other damage, like corroded wiring.
