No two way talk and erratic performance

"Doorbell camera ( 2k wired/wifi) will not two way talk and has very erratic performance at best. I have replaced my router with the latest mesh system to help and it still has problems. I also purchased a new nvr just to use this doorbell I have over $700 into this doorbell and it is horrible !! I could have bought a blink and subscription for the next 10 years and been ahead cost wise Soooo disappointing and costly mistake in going this route !!"

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."

Customer G. (5/5)

Affordable doorbell cam without subscription fees.

"Overall I like it. It's an affordable doorbell camera without subscription fees that works with older mechanical chimes. Make sure you check that your transformer is at least 16v, but it's easy to upgrade if it's not. Good: 1. Wired doorbell that works with my old mechanical chime. 2. Supports big SD card so I don't have to pay for Cloud subscription. 3. Easy install if you have a flat surface (but I had lap siding). 4. Does great detecting people near the door and getting good video. 5. The app is good, but can't always connect. Challenges: 1. I have lap siding and there is no mounting bracket for that. I also wanted it angled down a little and to the side toward the driveway. They provide two angle brackets but you can't use both. Fortunately, I have the skills to design and 3D print a custom mounting block to fit my needs. 2. With a brand new Sandisk high speed card, it would randomly tell me the storage was corrupt, but mostly recorded fine. I re-formatted the card in my laptop and so far haven't had that problem again. 3. The app occasionally has a problem connecting for Live View even though my phone has a great WiFI connection and I'm close to the router and doorbell. Maybe the WiFi receiver in the doorbell isn't the greatest? 4. While it's great at recording people near the door, it does not detect someone walking through the yard or vehicles driving by so don't expect it to be an overall security camera. I don't know what the range is and I have it set to max sensitivity."

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."
