I am new to CCTVs/Security Cameras in general so please bear with me…I’m trying to replace 2 wired analog security cameras at my aunt’s commercial property due to loss of video connection. The system is 8-10 years old, part of a Lorex L19LD800 8-camera dvr system. At this point, she prefers not to replace the dvr unless absolutely necessary. I suspect the BNC line has an interruption at some point but because the line is several hundred feet long and is routed through a warehouse up about 20-30 feet in the air along I-beams, I think it would be easier to replace them with 2 wireless cameras instead. The problem is that there is a building in the way which is an obstacle between the camera position of one of the two planned wireless cameras and the office where the dvr is located. The other wireless camera has line-of-sight to the office dvr.

From hours of Googling, I have seen discussions which seem to suggest that it is possible to set up a relay or repeater, which could route the signal around the corner of the obstacle building. I’ve included a diagram below to hopefully clarify the situation. I have no idea what such a repeater might be and would appreciate any advice or help in finding an appropriate device. I’m aware of wifi repeaters, of course, but since this is not wifi, don’t know what to even look for. I’ve seen a few during my web search that looked like they might be what I’m looking for:

I would recommend using the coax as a pull-string to pull ethernet. Hundreds of feet and repeaters around a building just sound like a kludge. Tell her to pay the money put a power over ethernet camera system in and be done. A $99 camera is also not going to last. You should buy quality commercial hardware, Axis, Panasonic, etc for your cameras and run them POE in my opinion.
