Reviews

Goes offline regularly. Have to

"Goes offline regularly. Have to take it down to reset it and then it takes multiple resets to reconnect if at all. Customer support doesn’t pick up the phone and troubleshooting guide is no help. I would recommend against purchasing these products."

— Matthew C. (1/5)

Product Failed Before Two Years, Terrible CS

"Purchased in June 2024, and it’s obvious why this product only comes with a one‑year warranty—it didn’t even survive two years before moisture leaked into the lens and completely ruined the video quality. The camera is now useless. Customer support was equally bad: no accountability, no discount on a replacement, and they couldn’t even be bothered to waive the $10 shipping fee. Overall, a cheaply made product backed by unhelpful customer service."

— Nick (1/5)

Replacement doorbell

"I love my Lorex system, including the Video Doorbell. But I have to say that this doorbell was a replacement after my 1st doorbell camera had moisture on the inside of the lens. Because it was out of warranty, my only option was to replace it. Because I have an 8 camera system that has worked well for nearly 6 years, I just had to go back to what I had. Overall Lorex has great products, was just disappointed that the doorbell was not better designed to prevent moisture from getting on the inside of the lens."

— Customer G. (5/5)

I DO NOT RECOMMEND LOREX ANY LONGER

"I DO NOt RECOMMEND, this camere was purchased july 3 2023 and didint last til 03/03/2026 before the internal battery that drives the in house ringer went bad. then your interior door bell stops responding. I CALLED COMPLAINED AND WAS TOLD TOO BAD SO SAD BUY ANOTHER. SO REMEMBER THEY ONLY LAST ABOUT 3 YEARS AND ITS TRASH CAUSE YOU CANNOT REPLACE THE BATTERY SO EASY. I AM SO UNSATISFIED"

— GLEN H. (1/5)

I am very pleased with

"I am very pleased with the Lorex 2K wi-fi doorbell. The setup directions were somewhat difficult to follow but the company support helped get me setup. I would recommend it for anyone that does not want a monthly subscription."

— William H. (4/5)

In addition to the Fusion

"In addition to the Fusion 4k NVR and phone ordered direct from Lorex , I also ordered a Lorex Chime from Amazon. I called customer support on the morning of (I believe) 3/26/26 with questions about the configuration of the Chime, phone, and Fusion 4K. I was met with a voice that sounded annoyed, short, and disinterested. He asked questions like he was reading from a bulleted list. I could not find a device ID right away, which really seemed to test his patience. The encounter convinced me that I would rather research the information on my own than suffer through another minute with this clearly annoyed individual on the other end of the line. If you truly record your calls, you have an excellent example of how not to respond to a customer's support call. This encounter does not deserve a rating, as even a 1 star would indicate some small redeeming quality. I am attempting to complete the installation on my own, if I cannot, you are getting it back; largely because this singular encounter makes me so angry to think about it."

— Alton C. (1/5)

Clear picture. Good app. That's about it.

"Picture is crystal clear and the app for the most part is very easy to use. But that's about all that I like so far. I didn't realize that this doorbell does not have 24/7 continuous recording when I bought it. I just kind of assumed that since it had a SD Card slot, the option for continuous recording was available. I guess that's more my fault since I made an assumption that this doorbell had a feature that most other doorbells with an SD Card slot has. Also the notifications are hit and miss with a lot more misses than hits. I'm getting maybe 1 out of every 4 motion/person event notifications no matter what kind of sensitivity settings I've got. And I guess person detection takes precedence over motion events since the doorbell doesn't turn on the night light when I walk by it at night. But if i check the timeline, I see that it recorded me walking by the camera and never sent a notification. Maybe I'm doing something wrong but it's been frustrating to learn about the shortcomings. I'm starting to regret changing to this doorbell instead of just buying the same brand I used previously."

— Darren (2/5)

Install went much smoother after

"Install went much smoother after connecting to the internet. System works well now"

— Werner H. (4/5)

Bad quality

"I’m using it for 2+ y. Pi’s of junk. 2k quality is no better than SH. Notifications always late. The bell works sometimes. Notifications when someone push bell bottom comes late and camera may not work properly. The support can do nothing."

— CJ (1/5)

Best Doorbell Cam

"Unit has plenty of storage, sound is great. Installation was easy to preform and setup was a breeze. I am able to hear clearly anyone at the door though the doorbell cam. My voice is also clear and understandable."

— Eddie M. (5/5)
