The solar driven device only transmits A/V when it senses movement (up to 26 feet away) Its video stream transmits over the crowded 2.4Ghz range, which means it might bite into your WiFi network, or receive interference from your microwave. With zero wires and a 250-foot range, you can set this thing up right next to a hot neighbor’s bathroom windowor, um, in your backyard. It isn’t as fancy as an IP based camera from D-Link, but this security camera keeps an eye on your property.”]
