It sounds like a firewall issue. You need to create an inbound and outbound rule allowing the port you setup for the app (typically 3000).
Here's an example of mine. I'm using port 3001.
With that camera you should be able to capture both sides of street. Here's an example of the zoom level I'm using and I get both side of the street. I do have two cameras because front plates are not required where I live.
You could define the area of interest (AOI) on the video tab. However, if you define the AOI, you might want to clone the camera so that you can capture both front and rear plates.
I’m using a cheap Govee Bluetooth vibration sensor. I tried using a zigbee and zwave sensor but neither worked mainly because it’s a heavy gauge steel mailbox surrounded by brick. The Govee sensor works well because I have several Bluetooth proxies scattered throughout my house and garage.
This isn’t using a model. There’s a sensor in the mailbox that triggers the AI analysis' when the door is opened. Using this methodology it also sends me an image analysis of whoever opened the mailbox.
I use tailscale and it shouldn't have anything to do with the ALPR database. Like @VideoDad mentioned you need to setup the ALPR database app on your LAN using the local IP address of your BI PC.
I haven’t had a chance to look into this yet, but I noticed 5.9.9.53 also broke my connection to @algertc’s ALPR database app.
Update: I found the issue... "objects0," is no longer needed in the custom models field.
There's no need to pay someone for zoom support. If you'll post your specific issues here I'm sure you'll get the support you need. By posting your problems publicly others can learn how to deal with these as well instead of keeping everything private.
