free home security system

DIY home security systems come in all shapes and sizes. Some systems come with an LCD panel that serves as the brains of the system. The panel is typically installed on a wall in a central area of your home and connects wirelessly to your home network. Most of these panels use capacitive touch screens and contain multiple radios that allow them to wirelessly control Wi Fi, Z Wave, Zigbee, and Bluetooth sensors and home automation components. Most panels also contain a cellular radio that connects them to a monitoring center if you subscribe to a professional monitoring plan, and they almost always have a speaker and a microphone for two way communication with a monitoring agent. The cellular radio is also used to push updates to the system. For example, the $229 SimpliSafe Foundation is a starter kit that gives you the hub, a door/window sensor, a motion sensor, and a yard sign. Additional door/window sensors go for $14. 99 each and you can order glass break detectors for $34. 99 each, smoke detectors for $29. 99 each, and water sensors for $19.

I believe its great value though as most people can do just fine with 1080p resolution. What is more important is that it supports advanced motion detection algorithms to cut down on false alerts. Besides you can always add more higher resolution cameras as 4 PoE ports are available for further expansion. Although it come with only 1 hard drive, you can add up to 4 in total for an amazing level of redundancy. You can even specify which cameras should be recorded on each disk – that is a degree of fine tuning that you cannot get in lesser models. I am not as happy about the lack of 4K output, especially as the NVR supports cameras of up to 6MP.
