Reviews

Easy to use, sharp and clear images

"Doorbell works great! Images and videos are sharp and clear. Connects to the Lorex App and easy to use when it comes to playback, 2 way talk, and live view. Currently have Lorex cameras set up so having the doorbell and cameras all in 1 app is very convenient!"

— CM (5/5)

I can't give a review

"I can't give a review because I can't get it to stay connected. I was switching from the competitions door bell that has been working fine, but if I can't get Lorex to connect, I may have to put my old one back."

— Customer Y. (5/5)

I like the video doorbell.

"I like the video doorbell. However the angle plate doesn't work for me. Hence 3 stars. Should include multiple angle plates like 60 degrees or available ss accesory to purchase."

— Satish P. (3/5)

I have sent back the

"I have sent back the unit as you approved. It did not work AT ALL! After wiring it in it could not even operate the interior chimes which proved to work with the old system. I spent a total of four hours with your agents to make it work with no luck. I made a 2. 4 and a 5G system but still would not pair. And your installation manual was disjointed about step progression. Never Lorex."

— ROBERT K. (1/5)

I've nothing but problems with

"I've nothing but problems with this device. Three calls to support have not solved the problem. Trying to connect to support is a nightmare. Last support call they asked for model number and serial number. And here I sit with a broken device and no return follow up. You can't even create a support email on the site. I would never recommend Lorex just based off the poor support they offer. I want to use them but not now, I recommend another device and with better support if needed, Very sad,"

— Paul H. (1/5)

Not really happy with the

"Not really happy with the camera. Camera takes a long time to load when someone presses the doorbell leaving them hanging around for 10 seconds or so before I can talk to them. I have fiber so internet speed is not the problem. Video quality is fine."

— Nicholas P. (2/5)

I've used other doorbell brands

"I've used other doorbell brands in recent years at different locations. I went with Lorex doorbell in my current location because I have Lorex security cameras inside/outside. Having the app already and just adding the doorbell was a simple task. The doorbell works great. Loads and responds accordingly. Clear videos day and night. Lights up when motion is detected. Especially at night when you can really see it well. Spoken with the delivery driver , communication was nice and clear . I didn't have a lag as I had with other doorbells. Recording works great. Im able to retrieve my recordings easily. The one thing I do know the Lorex doorbell camera needs is improvement on it it's coverage viewing. It's not enough of a wide angle. In comparison to other doorbell devices I have used. Overall it's a great device."

— Gabriel M. (4/5)

Extremely disappointed in technical department

"Extremely disappointed in technical department and customer service. The unit I purchased directly from Lorex on 22nd June 2026 was defective. Your technical staff took awhile to realize there was a problem and then had to call customer service who processed the warranty and promised to send an email within 24 to 48 hours. This never happened and I had to call thrm again today 6th July. I hope to hear bavk frombthem in snother 34 to 48 hours!"

— Ferdinand S. (2/5)

So far, the third time

"So far, the third time is the charm. This is my third Lorex wired doorbell and the first (so far) that works consistently. I also prefer this aspect ratio and people don't look like they're in a carnival mirror. It was super easy to set up too. My one complaint with Lorex is their app. It just isn't very user friendly and the timeline feature needs an overhaul. I have six Lorex cameras (including the doorbell), and the app is always the problem. This doorbell is great though, and I would recommend getting it."

— Adam M. (4/5)

Avoid this brand

"Waste of money. Constant network and hardware issues. Doesn't work when you need it most. The 9:16 aspect ratio is very annoying as well. You don't see what's important. Instead you see a sliver in front of the door, mixed with all sky. This causes it to not cover all the porch area, and miss a lot of movement or action. Save your money and do your research. Just buy the Reolink or the Eufy. Way better quality and connectivity than this garbage."

— Jon (1/5)
