Hello, I am not sure what type of camera (CCTV) is this! But I am asking for your help if you can suggest a provider for rotary encoders- our technician/electrician told me that it has a defective rotary encoder. Hope you can help ASAP. I attached the photo below.
I'm sorry but I'm not sure about cameras but you could always check dynapar for lists of rotary encoders that might be suitable to what you are trying to look for. You may also seek the assistance or other options in order to find the exact encoders model and probable replacements.
