home alarm security systems
Entry level systems usually include some door and window sensors, a motion detector, and a hub that
communicates with these devices using one or more wireless protocols such as Wi Fi, Z Wave, Zigbee, or a proprietary mesh network. You can add extra door, motion, and window sensors to provide coverage for your entire house and build a comprehensive system that includes door locks, garage door openers, indoor and outdoor surveillance cameras, lights, sirens, smoke/CO detectors, water sensors, and more. A word about wireless protocols: In a perfect world, all home security components would use the same wireless standard to communicate with the main hub, but factors such as power requirements, signal range, price, and size make it virtually impossible to settle on just one. For example, smaller components such as door/window sensors typically use Z Wave or Zigbee technology because they don't require a lot of power and can be powered by smaller batteries. They also operate in a mesh topology and can help extend the range of networked devices. However, neither protocol provides the bandwidth that you get with Wi Fi, which is why it is usually used in security cameras to provide smooth video streaming, and in other devices that require a fat pipe. Moreover, Z Wave and Zigbee devices are connected and controlled using a hub, while Wi Fi devices can be connected directly to your home network and controlled with an app. Finally, Z Wave and Zigbee devices use AES 128 encryption, and since they operate in a closed system with a dedicated hub, they offer more security than Wi Fi devices. Any smart security system worth its salt offers components that work together in a seamless environment and can be manipulated using customized rules. For example, you can create rules to have the lights turn on when motion is detected, have your doors unlock when a smoke alarm goes off, and have a camera begin recording when a sensor is triggered. Some systems store recorded video locally on an SD card or a
solid state drive, while others offer cloud storage.

Where do I begin?Bizarre design choices such as using a micro USB cable and camera connections instead of regular old network cables and RJ45 ports, and deceptive marketing which then calls this a “network cable” which it is anything but!I have never ever seen a “network cable” that has one RJ 45 end and a USB connector at the other end. Hi Steve, thanks for dropping by!I call these NVR kits the EasyDIY solution to home CCTV but my preferred option is FullDIY where I run everything off one small NAS box, my QNAP TS 253A. I have 4 cameras and the QNAP Surveillance Station takes care of my needs nicely with redundant storage and an OpenVPN server all for under $500.
