Cobra 4 Channel Wireless Security Camera System with 2 HD Cameras & 7" LCD Monitor (Model 63842) - Indoor/Outdoor Home & Business Surveillance

I installed these at my daughter's house and they work really well. The app works well with them.This is a nice, stand alone surveillance system, for the price. Picture is great and the intercom works very well. The night vision is spectacular!Downsides:1. It doesn't indicate which camera has seen motion detection2. To use the phone app, the monitor has to be hooked up to the router with an ethernet cable. I had to buy 50ft extra, to place this monitor where it's convenient.3. Comes with 2 cameras with the capability for 4...extra cameras are approx $89 each. 2 more cameras are almost as much as the whole system!Overall, this was very easy to install and does not require wifi, unless you want to put the app on your phone.Can’t get phone to alert me when motion is detected.installed as per instructions. a little learning curve on the menu but up and running and functioning 24/7 ever since. LOVE the always on screen, no upload time while wanting to view camera.Easy install , no cloud fees or monthly fee , memory card in monitor not outside to get picked Off . Stopped neighbors letting dogs run wild ,quite now they know it there .....We have the cameras in the barn. Very clear during the daytime and when it switches to night visionI bought these System and they don’t have a battery in them. But they have a really clear View .Very useful for security at my home.
