This WIFI doorbell is absolutely great. It provides me with the confidence of safety for my home. It is completely wireless and has a great 720 HD view. It has a motion sensor detection feature and it also offers night vision view. It has real time video, which allows you to monitor your door or the view from your door anywhere and anytime. It offers two way audio, this allows you to communicate with whomever is ringing the doorbell while watching them. The wide angle allows you to get a great view of what i front of the camera as well as the surroundings. One of the best features for me is the 16-GB SD card that comes with this video doorbell. It definitely does not get any better than that. Other the fact that this system is completely wireless. So just install it, turn it on, download the app on your android, and secure your home starting at the porch. Do not think for one second I am just saying these things, for products that must have time of use for a honest review. I actually hold on to them and use them for more than 30 days, some times more to ensure what I am telling you my honest opinion. I have had this well over 2 months and I definitely believe it would hold up comparison with the more pricey named video doorbells. I recommend this for any outside access door you have.
