hi to all i am new to this forum and not expert in CCTV systems but i have some questions about an update they perform in my workplace about the CCTV system we work i would like to say sorry about my English from the start and my limited knowledge in CCTV systems maybe i cant give enough information so you can explain to me what causing these problems.

 

First of all the cameras we are using are analog about 150 cameras they used video encoders so the new digital system can work but the result was bad quality picture especially at night

 

thank you all

Your encoder is D1 compression?

Try an alternate power supply. If you don't see any changes, check your cable and make sure the connectors are fastened securely. If you still don't see any changes, you might have a ground loop issue; a ground loop isolator may be worth trying at that time.
