Looking for suggestions on a CCTV system for my friends warehouse.
Security companies want $35K to $45K to install. Nuts!!

We want to install our own CCTV system instead:
BNC has limitations on length of runs. Some runs from camera to HDVR will be up to 1,700 feet. I don't know if BNC amplifiers will give us a good enough signal boost.

We could go with a 16 camera/port setup. Prefer onsite HDVR rather than cloud based. No need for a 3rd party monitoring company or being hooked up to our alarm system.

We have a Mesh WiFi system. We don't need PTZ cameras at this time but if needed in the future would be nice to be able to use with the system we buy. If we use cameras for Mesh WiFi security I would assume we would have to power each camera by plugging it in?

I have a Zosi system at home with BNC. Not bad. But the HDVR GUI is more DOS than Windows based and a bit annoying.

Suggestions appreciated please. Brand systems? Types of systems?

Thanks so much!!
