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."

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."

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."

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"

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."

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."

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."

Not recording properly. I am

"Not recording properly. I am not happy with this one or the previous one which became blurry over time."

Had received a defective phoenix

"Had received a defective phoenix connector for the doorbell chime connection. Had to spend hours with customer service to get a replacement only to receive another defective connector. Spent more time with customer service and asked for overnight delivery because I was going on vacation. They refused. I ended up ordering the defective part on Amazon and it took me five minutes to install. Really disappointed in the urgency of customer service. That being said the product works pretty well."

First 2k wired camera defective out of box

"Doorbell only works w connected to usb port for id/ pw set up , w hooked up to brand new doorbell transformer nothing , reset appropriately 10 x then gave Lorex tech support / return n a call they made me go to tech support first , I was on w them for an hour going back n forth about take pictures of transformer label, take pictures of id on doorbell microscopic label, take a picture of voltage hooked up to doorbell , then forward them back , then they can’t read them , too small , keep in mind I’ve only ordered one x ever from them , they had all my info already and I was willing to send it back first , , didn’t even get the full RA number was going to call back or email me , I’m thinking if I don’t get a new device that works I’m sending back all of it , I’m not a fan of over seas support either . Keeping my fingers crossed for good luck ."
