The installation was very easy, excellent coverage with lots options for controlling. The light is wimpy! The is substantial time lag from a live event to whe it's viewed for a response. Annoying!

Good Doorbell Camera Overall.

Easy to install, and fits better than the Blink I replaced. When it captures an event, it sends a message to my phone in approximately 18 seconds, which is much better than the 2 minutes I was getting with the Blink. I do not like the watermark in the upper left corner that is always there, and it sometimes fails to see people walking up to it even though it is a "fish-eye" type camera.

Very disappointing

I purposely avoided Amazon Ring because of privacy concerns and chose another brand instead - but now I'm regretting it. The camera worked fine for about a year, though the initial setup was a hassle. Now it's just sitting there flashing a blue LED and not working. When I reached out for support, all they asked was whether I had an extended warranty. Very disappointing.

Great doorbell

I bought this to replace a Lorex 4k camera that stopped working shortly after installing. It could not be reconnected as it would not send out a wi-fi signal. We are still waiting to get a refund on that one. We have been told that Lorex only sends replacements, and we don't need another doorbell, especially a 4k one.

Same problems as my first Lorex

My first Lorex lost the wifi signal about once a month. In removing it from the bracket to press the reset button, I dropped it & scratched the lens. Since I also owned the Lorex chime, I purchased another Lorex video doorbell. The new one lost the wifi signal after the first week, plus I had to reboot it twice in the past 3 days. It is only about 15 feet from my wifi router. The 2k feature provides a clear, clean video & the unit has good motion detection. These technical problems should have been corrected in the newer version & the reset button should be easier to access.

Beware

Lasted 2 years 3 months. Technical Support said transformer needed to be upgraded, did that, no help. Finally said camera was bad, only a 1 year warranty. So I'm out. Offered a $10 discount on new camera. I took it because price had dropped so much on the camera. Now have a 5 year warranty. We'll see??

Sun Baked Lens = Blurred Vision

Our door faces the south so the southern California sun slowly bakes the plastic so the view becomes fogged. Like fogged headlights on many cars. Better materials would prevent this problem. After three years, the view is so fogged we have to replace the unit.

Great doorbell camera

By Arnold K.

Easy enough installation, replacing an old wired doorbell. Everything you need is included in the box except for a drill and screw driver (even the drill bit is included). I did need to replace the transformer (mine was 10v, specs call for 16+v) which I bought at Home Depot (not expensive and easy to install). I have an old, mechanical chime which now works better than before. If you have a mechanical chime you need a small converter which is included in the package. The camera picture qualit...
