I took my camera apart, and unless the mic is hidden somewhere, it does not have an onboard mic. I would assume that if there was one, it would either be on the lens cover and would have a lead back to the main PCB, or on the PCB itself if it were meant to detect noise rather than record...
I have but couldn't get it to work. When I formatted the SD card, the camera crashed. I might have a bad SD card, and since I didnt need on camera storage, I didn't look further.
Line in required the signal to be around 1V or so, so you cannot just wire up a condenser mic to it, the signal level is too low. The device you have could be used as test to see if line in actually works. If it does, then there are "mic modules with line out" on amazon for about $4/each...
What are your timeout values in the main AI setup? Have you tried adjusting those up to see if that helps? The alert looks like it is being cancelled by AI, that's why it ignores the rest of it. Was this working prior to .49?
Thanks, it's been a while since I've used a camera w/o audio. I was hoping that it was the Vigilant firmware that disabled the audio, since they didn't need it, but the mic was on board, but looks like their standard firmware doesn't enable it either. What's kind of interesting as I was...
I'm not exactly sure what the official way to do that is, I'm on a RKNN SBC, so it's a little different if you are running windows.
/app/modules/ALPR-RKNN/modulesettings.json
Has all of the settings, so I'd imagine you'd edit this file and restart the module.
So Vigilant is no longer around, they got acquired by Motorola. That's why these cameras are so cheap on ebay, and if you got a lot of time on your hands, you can probably piece together all of the original HW and SW to get a system working as it was intended---cameras mounted on a police...
Yes, BI to take the video feed from the camera and send that to CPAI for AI processing. Then if a plate is found, have BI send that data to ALPR Database so that it can be searched. It takes a little effort to get all that going, so it works pretty well...
You may want to leave the stock firmware on the one you are going to use for LPR unless you have a reason to upgrade. The Vigilant firmware was probably made specifically for LPR--I am not sure what the difference would be, but I would think the IR lamps work differently?
I am planning to...
It sets the min confidence to 30, which overrides whatever it is set in the GUI in BI. I left it in while I was trouble shooting some issues where CPAI would return values that fall below the threshold (in my case it's 70% in CPAI) and it should have been rejected by BI, but BI sends it to...
If you are getting this, your schema doesn't seem to be applied. See this thread on how to do it manually:

This is what I have:
{"ai_dump":&JSON, "Image":"&ALERT_JPEG", "camera":"&CAM", "ALERT_PATH":"&ALERT_PATH", "ALERT_CLIP":"&ALERT_CLIP", "timestamp":"&ALERT_TIME"}
I use the camera for ALPR and I think it works way better than expected. Here is an example from this morning, I have the $35 camera pointing north, and an actual ALPR pointing south, so the images are of the front plate (south facing) at around 140ft and rear plate (north facing) at around...
And changing that to something more suitable doesn't work? Have you tried auto? Have you tried day mode, or anything else? Or are you saying you've made changes to the settings and you are still getting a poor image?
In case someone else runs into this in the future, this was caused by CPAI thinking there is a 2nd plate in the frame. It does not draw the bounding boxes around it, but it does seem to send it over the JSON data. You can confirm this by looking at the CPAI logs by searching for the 2nd...
Has anyone else seen this issue? The CPAI reads the plate correctly, and it's burned into the image correctly (see bottom right), but it's taken into the database incorrectly (see top left).
When this happens, CPAI has some tracebacks:
SyntaxError: invalid syntax
18:07:49:License Plate...
