This is a very basic question from a nearly totally ignorant poster in the USA. I am having a house built, but it's not mine until I close. Thus I cannot string my own video/alarm/etc cables until the sheetrock is up. However, the builder uses a Security Firm sub-contractor who will install a 4 or 8 camera system (Samsung like the SDS-P5101 uses "BNC/Power extension cables") for $2k or $4k respectively, USD. That's a lot of money. These are "wired" not WiFi (wireless?) cameras. He could, however, install just the cables (now, before the sheetrock goes up) for about $100 per camera. I am thinking that's a better option, money-flow wise. I meet with the subcontractor next week to discuss details.
My Questions:
1. Is there any sort of standard for video cables?
2. What are "BNC/Power extension cables" - is THAT the standard...or a standard?
3. Assuming those are standard cables, what cameras and NVRs might be "better" than Samsung? I do not need anything special in the camera other than quality...the functionality of the Samsung cameras in the kit above is fine.
4. If the ones Samsung uses are not standard, what other cameras and NVRs (etc?) will function properly with the Samsung cables?
Thanks!
