"Device Storage Corrupted"

"Constantly sends warning that device storage is corrupted. I'm on my third sd card now, same problem. As soon as it hits about 32GB of stored video, "corrupted". First on a 256 sd card, now on my second 128 sd card. Also, this 2K doorbell uses 4 times as much sd space as my 4K driveway cam does. Something is not right. Not happy. Also goes offline randomly."

The system is nice for

"The system is nice for letting you know who was at your door. Since it is based on WIFI, there is normally too long of a delay for you to be "live. " So it helps to track the past. That does help catch criminals after they had time to enter, but generally not before. So you just have to have realistic expectations as to how much security they provide."

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 !!"

Basically Worthless

"Can’t view live view while it is recording and if someone rings doorbell it stops recording so you get no recording of what they did after ringing doorbell."

"It's nice but constantly looses connection. I have to reconnect it on a monthly basis. My other Lorex cameras don't have that issue."

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."

The advertised features of the

"The advertised features of the Lorex 2K wired video doorbell would have been a great configuration compared to most other brands. Installation was straightforward and the kit has parts to cover a variety of mounting situations. Unfortunately the Lorex Classic application software performs very poorly and has a terrible user interface. It even crashed during the basic setup sequence. Typical response times to connect to real-time video or playback of recorded images is very slow, making it almost unusable for answering a visitor before they give up and leave. Often the application initially displays "Uh Oh something went wrong" and prompts you to tap a retry button, leading to multiple failures before eventually producing a result. Mechanical chime actuation was a significant selling point, but it functions intermittently, often requiring two button pushes and then ceasing to respond until after a long delay. For the price point, the unit should at least properly replicate the function of a simple momentary contact switch, even if the video fails. The custom quick message recording function always causes the application to crash with a message that actually displays "Lorex Classic closed because this app has a bug. " If there's a known bug, why memorialize it with a message instead of releasing a functional application? Android OS gives warnings about excessive crashes of the application and recommends removal. Problems occur even under ideal unloaded high-speed Wi-Fi connections on both 2. 4 GHz and 5 GHz bands. The same problems occur whether operating from wired a. c. input or from a separate verified d. c. supply connected by the supplied microUSB cable. When it works, the WDR video quality is good and audio is usable. Nightlight and siren features are a nice extra. The unit gets very warm, which raises a concern for longevity. There's no indication Lorex intends to remedy its acknowledged defective software for this product. I regret the purchase and recommend not ordering this product until there is clear evidence that Lorex has cured its design defects and poor application software integration."

"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."
