It looks like Lorex has released a new 4K doorbell. Curious to see what the reviews will be.

I have the Lorex 2K version and it's fine unless you have to zoom in close and then it gets blurry. Maybe I'll upgrade to 4K when and if the price is right. :lmao:
 
A quick look at the spec sheet and I’m not sure if I would be a fan of the 9:16 aspect ratio. They advertise it as a feature to see someone head to toe, but I use my doorbell camera as the main front camera as well, and would prefer a wide angle. I also wonder if this is an app ratio only or the sensor, because I know for my Lorex 2K the ratio in blue iris differs from the app (I think the app stretches it).

Yes....I prefer and like the wide angle view as well. My front porch sets up high so I automatically get the head to toe view on approach to the front steps, plus a wide angle street view. I'm not sure if they'll be using the same phone app or a new and different one for the 4K version.
 
I just installed my Lorex 4K doorbell yesterday if anyone has any questions. Previously I had (at a different house) a Ring Pro.

  • Lens/sensor quality seems quite good, but I do wish the bit rate was higher. No adjustments that I can see.
  • Very little lens distortion.
  • would like more than 15 degree angle tilt mount. But they can’t be stacked either.
  • 9:16 aspect ratio is fine for vertical but YES I really would like more horizontal. Certainly a wider angle lens would help too.
  • Automatic nightlight is nifty
  • Bundled chime kit works fine with my mechanical chime.
  • IR night vision sucked (murky/washed out), but then I realized today I left the protective film over the lens. Will try again tonight.
  • Color night vision surprisingly good considering I’m in a zero ambient lighting area (brightest thing is the doorbells own button light), but no real useful experience with it yet.

Received and Installed mine yesterday.
  • Seems orders of magnitude better than the 2K version, especially in direct sunlight.
  • Used some string to measure ~65 degrees horizontal FOV.
  • The porch pirate package detection works well.
  • Only thing it lacks is individual sensitivity levels for each detection mode.
  • HKSV supports portrait camera fairly well on iOS, iPadOS, macOS, watchOS, except tvOS (submitted bug report).

Thank you for this initial information. Can you say something about Onvif and RTSP-Stream? I couldn't find any information about this on the Lorex website.
Is it (maybe) also an OEM model from Dahua? Is there any information about API?

  • Lorex doorbell cameras are not ONVIF compliant and do not have the same API as the Dahua or Amcrest equivalents, but you should be able to connect them to a third party NVR using the RTSP protocol.
  • There is a RTSP stream and sub-stream. It's the same URL as their NVRs
  • Example: rtsp: / /admin:[redacted]@192.168.69.89:554/cam/realmonitor?channel=1&subtype=1


I have all my Lorex cameras connected to HomeKit via Homebridge

I've been struggling trying to get my 4K Lorex Doorbell to not be so laggy as well as enable audio and motion / doorbell sensors for Homebridge Camera FFmpeg. The Homebridge Dahua Alerts plugin keeps saying my Lorex refuses to connect. If you could share some knowledge on how you set this up, that would be awesome! I've been messing around with various configurations and still no dice.

Welcome!

Unfortunately, Lorex cameras do not support Dahua/Amcrest APIs for events or two way audio. Don’t use the Dahua plug in. Use the generic Homebridge Camera FFmpeg plugin.

Video lag can be a result of a number of factors, including the performance of the host or virtualized machine, and which software encoder (if installed) or hardware encoder (if supported) you select. I run a HB instance on a MeLE Quieter 3C running Ubuntu 22.04.3 LTS


You can enable virtual motion and doorbell events, which you can send HTTP commands to trigger virtual events. Example, I have an adjustable AC current sense relay connected to the common wire of the doorbell transformer to trigger a discrete input to a security panel, which then triggers a HTTP command to cause the live video thumbnail to appear on my Apple TV. Works automagically!

Thanks for the quick response! I ended up going with Scrypted using the RTSP plugin because the audio works. The stream lag was only on my iPad and after restarting it, it went away!

I looked into the person who was able to get their 2K model's buttons and motion detection working on Scrypted via MQTT. Followed their steps and it appears there is communication between the docked DahuaVTO2MQTT device and the MQTT broker, which I'm just running using Scrypted's MQTT plugin. I had to edit one of the DahuaVTO2MQTT files in the container so that it points to port 35000 (the only open port other than RTSP 554). The default 5000 port won't work. However, the MQTT buttons that I created are non-functioning despite there being communication. I was hoping the 4K model wasn't too different from the 2K model. I even tried using the Amcrest plugin but because the 4K camera doesn't have any open HTTP port, I'm unable to add it.

So I couldn't get the camera's door button and built-in motion sensor to work in Homekit, but I was able to get motion detection through Scrypted's OpenCV plugin. It shows up in my AppleTV and I get notifications in Homekit.

Has anyone tried connecting to it using Dahua SmartPSS? I use that on my Lorex 2k. Just wondering if that could be used to adjust the config on the 4k.

Hmm. Haven’t tried SmartPSS (will do that later) but I got it working with DMSS (iOS) on port 35000. It logs in, lets me see the streams (correct aspect ratio, sound, seems like it might allow talking too), view all motion recordings (seemingly a heck of a lot more than the Lorex app gives me).

But it won’t let me try to change anything but IR mode. It gives me a “locked”’ icon and when I click it, it confirms I want to unlock, but then says “failed to unlock”.
 
Good news! The configuration options seem to come up fine in SmartPSS. I was able to bump the UHD encoding bitrate from the default of 2048 to 6144, and change audio from whatever crap codec it was using to AAC, but I can’t seem to change audio bitrate. Can’t remove the Lorex watermark. Does seem that it’s a Dahua beneath it all.
 
I picked up the Lorex 4K Doorbell on sale.
So far it is working rather well. The App has given me a few issues however.
I got it installed today and am still going through the config but I was able to get the video into Blue Iris.

One frustration is figuring out which firewall ports I need to open to allow the app to work.
It appears to pick a random UDP port from about 3000 up to 50000 so far. I would prefer it stuck to simple small range that can be allowed out with a firewall rule.
 
Did anyone get the Audio Stream into BI? I'm not looking for two way, but a stream would be good

Edit. NVM, I got it. I needed to set the auto type as RTSP

Hi,

I am interested in this doorbell system. My current home bell setup is when front mechanical bell rings it sounds one, when side rings it rings twice.

my question is with 2 video doorbell do I connect one chime kit to front and trans on the door bell sounder and the second chime kit to rear and trans so that each one sounds as it did before>

Not getting much help from Lorex when i call them

Thanks in advance

Welcome!

Steps

1. Video doorbells continuously draw more current, so you have to make sure your existing doorbell transformer is rated for the additional load.


2. Check your existing doorbell transformer ratings and mechanical mounting and look for something compatible. 16VAC/30VA should be sufficient for two video doorbells.

Example: Defiant Wired 16VAC/30VA Doorbell Transformer, Compatible with Most Video Doorbells 18000044 - The Home Depot

3. Follow the instructions, turn off circuit breaker, install the supplied chime kit in parallel at the mechanical chime Front-Common, Rear-Common (one for front, one for rear), remove old doorbell, install new door bell connecting the 16-24 VAC wires to the screw terminals. The chime kits take up additional room and may not fit inside the existing mechanical chime cover. So I made a cover using 1x2 and a perforated metal sheet from HD. Added brown construction paper to hide the chime internals.

4. Turn on breaker, use the app to scan the QR code to start the process, and select existing mechanical chime during setup.

I personally powered my Lorex doorbell cameras using the supplied USB power cable and got them all configured before installing them.

CAUTION: Do not connect the video doorbell without installing the chime kit first. There is a non-replaceable surface mount fuse inside the doorbell that will blow if you configure the doorbell to use an existing mechanical or electronic chime and press the doorbell button. You won't be able to power the doorbell using 16VAC power any longer. Don't ask how I know. :D
