Wired Camera Systems
Wired camera systems supplied with their own recorder. No batteries to recharge and no Wi-Fi connection to drop, which is why this style is still what most people install when they want coverage they can rely on.
Everything records continuously to the included NVR, sitting on a shelf in your house. Nothing is uploaded, nothing is rented back to you, and there's no subscription of any kind.
These are a bigger job than wireless kits: cable runs from every camera back to the recorder. Plan your positions before ordering, or budget for an installer.
