Reviews

Dead notifications

"My 2k Doorbell was working fine until a year and a half. Notication alerts stopped working. Doorbell still works and records ,but no more notifications. I reset doorbell and app did all the troubleshooting and notifications still don't work but they work for my other 2 2k cameras I bought from Costco. My tenanant bought 1080p doorbell a month after mine and her still works. Doorbell not reliable for long term if they don't fix this issue."

— Fernando (1/5)

Our Hikvision doorbell camera failed.

"Our Hikvision doorbell camera failed. We are so happy that we chose Lorex. The user interface Is extremely friendly and installation was simple and straight forward. The features available on this camera are amazing. The app itself is a breeze to operate."

— Gordon W. (5/5)

Just got it hooked up

"Just got it hooked up today and is working great, this is my 2nd one."

— Allan C. (5/5)

Very disappointed with the Lorex

"Very disappointed with the Lorex Classic App, does not work every time, reduced to the lowest video and set on SD a little improvement. I switched from the Ring door bell, the Ring App is excellent. You can hear the notification clearly. Need to fix the Lorex App. . it’s a hit and miss,"

— Winston C. (3/5)

Crashes every notification

"Rarely works. Always stuck in the loading screen/crashes at every single notification. Tried different routers/ 2. 4 or 5ghz nothing fixes it. Definitely issue with doorbell"

— Chris (1/5)

Awesome video doorbell, love it

"Awesome video doorbell, love it so much we purchased a second one for the back door. Excellent video quality. We are pleased with this product."

— Sundie B. (5/5)

So far so good haven't

"So far so good haven't had it too long but great so far"

— Myles B. (5/5)

We have a wired Lorex

"We have a wired Lorex doorbell at our main house and a battery-operated one at our cottage. The wired one works all the time. The battery one often goes offline. If the person at the door rings it like a doorbell it works right away but the camera does not report anything for several minutes. It is useful for looking at notifications when we are not there, keeping in mind that there is a significant lag. Great for watching for deliveries. Less useful for speaking to people if they don't ring the bell."

— Janet K. (4/5)

Versatile Doorbell

"In the overall, installation was straightforward (both, physical and app). The model I chose is working as expected, it has been consistent and image quality is excellent. Even at night, the device appears to have IR illuminators. I also like the button light status and how it changes when a person is detected, it kind of bring awareness and to some degree might even be a deterrent. Only concern is with the device being stolen: is the microSD card encrypted, and would anyone be able to extract the wi-fi password? As a physical security professional, I was also able to access the video+audio RTSP and connect to my NVR. I would recommend this product over many others that require subscription, which is the main reason Lorex was chosen."

— Felipe G. (5/5)

Easy install and setup, paired

"Easy install and setup, paired easily to my existing Lorex NVR system, picture quality is very clear."

— Wayne S. (5/5)
