For fixed views around a home or a small business, we install wired PoE cameras on a recorder inside the building. If a building already has camera coax in the walls, that cable can often be reused instead of pulling new wire. A second building or a long gap with no cable path can be linked with a dedicated point-to-point wireless bridge, which is separate from the building's Wi-Fi, and we will say so on the quote rather than leaving a camera on a weak Wi-Fi signal.
You can price a complete wired system yourself with upfront prices in our camera system builder at diyprosecurity.com. Pick how many cameras you need and which ones, and the builder sizes the recorder to your camera count. Then add the hard drive, cable, a PoE switch if you need one, and a monitor. Our technicians program and test the system before it ships.
