This is because DVR based analogue systems are on their way out, they simply cannot compete with the quality and convenience of network cameras and NVRs. Cameras – Network cameras a. k. a IP cameras are fully digital – the image is sent digitally to the NVR
through a network cable instead of an analogue BNC cable as in a DVR based system. This enables resolution higher than 1080p2MP, and currently you can go up to 4MP. The hard drive that will store the recorded video and
images – read my detailed guide to selecting the right hard drive.
They usually use touch screen hubs thatcontain RF, Wi Fi, Zigbee, and Z Wave radios, allowing them to communicate with and control a multitude of components including door and window sensors, door locks, glass
break detectors, indoor and outdoor cameras, light switches, motion and water detectors, smoke/CO alarms, thermostats, video doorbells, and a host of other home automation devices.

Worse, they detect burglars only after they’ve entered your home. That can create a dangerous situation where you come face to face with a burglar in your hallway. Door and window transmitters are the only way to detect break ins immediately. Don’t let anyone convince you that motion detectors alone are a substitute for them. Glass breakage sensors are available too, but are optional. Most burglars only break glass in order to unlock a door or window. Then, when they open the door or window, a standard transmitter
will detect the entry. Next, decide what kind of control
panel you want. There are two types: A “cabinet style” panel consists of a keyboard that mounts near the door and a circuit board that mounts near your phone interface. A “self contained” panel is a single unit that mounts near the door. This one part panel is easier to install but has one weakness.
