I got this a few weeks ago due to some break in's, in my neighbourhood and the advantage of this units are i can monitor the perimeter of my house, record anyone lurking, manually set off the security alarm or talk 2 way to friends and or visitors if needed when i'm out. Although i think this product is fantastic, i did have issues trying to setup and configure the wireless securing cams on my windows PC and android tablet, In the end i was only able to complete the setup for the security camps on my iphone for some reason.
