Greetings,

 

I have limited to no cctv experience.

Seeking information I came across this forum.

 

We have an office/hvac shop that we have a 16 camera dvr system that is aging and the cameras and hard drives are starting to fail.

My friend that helps with our computer network says it is probably time to upgrade.

 

We have 4 indoor and 12 outdoor ir cameras. There is siamese audio/video/power rca jack wiring connecting the cameras to the dvr. There is a network wire connecting the dvr to the computer we use to watch/view/serch this in the office area.

 

What are some of the available options/systems which we can use the exisiting wiring?

 

Regards,
