    Dedicated License Plate Cam project

    19 is about where mine is. I get really goid shots there. I spoke with the Blue ziris developers and they added a millisecond option for snapshots. If you uograde to the latest version its there. You can combine the snapshot on trigger action with an ALPR script.

    40 degrees is probably a strecth. You may be able to visually see them, but ALPR will be tough.

    Biggest thing to consider is the location. Angle to target and distance to target makes a world of difference. Shoot for 20 degrees or less at around 60ft if you can.

    Dahua Snapshots to NFS

    Do Dahua cams have the capability to jush push jpegs to a network file share? Say every 250ms or so?

    Do you have a python example of that? I'd like to try and trigger alerts on person detections

    That is pretty cool. That could be useful to cut out just the car only for analysis. Or just do motion alerts on "Person" for other cameras.

    Dedicated License Plate Cam project

    Here is the python code for the three files I use. One analyzes, one does the image pulls from the cam, and the other adjusts the focus at sunrise/sunset. Hopefully this helps some, I am not a professional programmer so you can probably make it a lot better. ----ANALYZER---- from openalpr...

    From my limited experience, I'd get the 4MP dahua that can do varifocial. Once you have your target spot sets its nice to be able to refocus it between night and day. Its big though compared to some of the smaller bullets. Depending how you are oriented you need to be at around a 15-20 angle...

    Dahua with Yawcam? Or similar tool?

    Cam: IPC-HFW5431E-Z5 Does anyone know if this has a mjpg option for a YawCam stream? I am looking for a product that can take snapshots after motion is detected down to 250-500 milliseconds apart. Blue Iris can only do it down to 1000ms intervals. Yaw Cam I have done this with for older...

    One thing I noticed when having an automation script change the Day/Night profile and refocus/zoom. You need to add a delay in between the profile change and zoom change. Apparently the IR/Profile might cause a auto-focus or something. It overwrites the focus setting that immediately followed...

    And today was OpenALPR fun day. Set this up to scan for Blue Iris motion snapshots and read them and add text to their images. Now to add database integration.

    OK, I am a believer in the Dahua 5431 4MP with 35mm zoom. This is at around 90-100ft. Camera is at a 20 degree angle to the target. Shutter: 1/500 Iris: 50 Gain: 0-25 3DR: 20 And here is the Python code to use the requests package to adjust it. Sun Up #Set Profile to 'Day' url =...

    Thanks for sharing this @nayr . I had my LPR dialed in last night and couldnt figure out what changed. I'll be setting up the same sort of thing in Python. I also need to do like you did and manually switch between Day/Night to enhance dusk/dawn plates. I have the 5431 Dahua that goes to...

    SUNBA 1080P HD, PoE+, 20X - 601-D20X

    I wouldn't recommend Sunba for most uses. Its not very useful at night. *Manual exposure settings seem to not work *IR doesn't stay off when you turn it off *Auto focus doesn't work at max zoom. Presets do not appear to retain focus settings *The 507 model has no upward tilt. So you have to...

    Dahua 4MP 25mm LPR Modification

    I just ordered IPC-HFW5431E-Z5 from AliE. Looks to be exactly what I was looking for to do LPR.

    LPR Location: Need camera / Lens advice

    I am looking to add a LPR camera to capture cars leaving the culdesac. My system uses 3MP 4mm and 12mm hikvision bullets. Would a 12mm hikvision bullet be useful in this scenario or would I need something zoomed in a little further? I feel like the angle and locationa are good but I just...

    Vehicle speed determination from video

    I've done it with Python code in the past and took multiple snapshots of the car one motion happened. I got it within about 5-8mph. My camera was at an angle on the road so it was hard to get much more accurate. If you had a camera face the road head on it would be easier to dial in. When I...

    Python Code to change text overlay & shutter

    The getpass Python module is probably the more secure way to capture the password than what I did. Call me lazy :)

    Hik DS-2CD2032-I Night time motion blur

    I had pretty much the exact same problem. I ended up just putting a really low watt light bulb in the fixture directly by it. If I go set my digital noise to 100 during the night I will get that exact same problem in your photo.

    Python Code to change text overlay & shutter

    Sharing this in case some or all of this is useful for others. I have a $35 Raspberry Pi2 linux system that Im using at a camera constroller. I plan to do more with this in the future, but for now this is where I'm at with it. I use the same Raspberry Pi2 to control my lawn irrigation...

    Set the digital noise reduction to 50. Mine does this too when its set to 100.
