After comparison shopping, I chose this video doorbell based on the advantages of no monthly data storage fees, the price, and the positive reviews, and I'm glad I did. If I could give 10 stars, I would. Installation was relatively simple and took about 30 minutes to get it up and running, including downloading the software and getting it set up. The HD image from the camera is bright and clear and the angle is wide enough that it “sees” approximately 25 feet to the end of my yard, even at night. Its microphone and speaker pick up and transmit voices clearly and easily understood. Because this doorbell was hardwired to the existing doorbell wiring, the regular doorbell chime sounds as well as the chime in the software, which I like. Storage of “events” is on the included micro SD card, and it is easy to clear the unnecessary “events” to increase storage space on the card. Predictably, resolution declines somewhat as the view is zoomed out toward the street, but it's still sharp enough to make out details of vehicles (e.g. the mail truck) and basic descriptions of people. Perhaps the motion sensor is a bit too sensitive; in default mode, it kept alerting to motion detected in some moderately high winds, when plants and the neighbor's flag were being blown by the wind. A minor tweak of the settings fixed that issue, such that it did not alert to motion detected when a cat walked through the yard; however, it did alert when a large grasshopper flew near and across the field of the camera. Once this was solved, the only issues that I have with it is that (1) there is no version of the software for a desktop computer – only for a smartphone. (2) It also occasionally disconnects itself and a manual reconnection is necessary, and (3) the software could been designed with additional buttons so that when in the settings or events mode, a button could take you back to the live video instead of the extra steps of having to clear the cookies out of the smartphone and restart the software. These minor glitches aside, this video doorbell is an excellent value for the price and I highly recommend it.
