    Many thanks. Do you know if it does a cropped substream image that I can feed openALPR?

    Dahua DH-IPC-HFW4431M-AS-I2

    Hi. Ive just bought 2 of these (one at @12mm and another at 6mm which I might end up setting up on my neighbours property for him) to play with OpenALPR. My understanding is that they will only run chinese hacked firmware and that newer updates are signed so cannot be decompiled? Could you let...

    Dahua IPC-HDW4231EM-AS review

    This is a fantastic review - Thank you. This camera has been on my shortlist for a while. I need a cheapish camera to use with OpenALPR with excellent night performance. The key here is that you can get a well exposed numberplate without it washing out due to over exposure? I understand that...

    Advice for ALPR camera in the $160 bracket

    Hi, Im looking for an ip camera to do day and hopefully some night or at least dusk license plate recognition. These new starlight Dahuas interest me due to their low resolution cropped substream and good low light sensitivity. My setup is as follows: 3.5m wide entrance 8m away camera mounting...

    Suggestion for a camera setup for pharmacy

    12mm doesnt have many applications indoors unless its a warehouse. You might use it directly over the till or prep area, this would give you a very small field of view. conversely 2.8mm is very wide - almost fisheye it will give you a good coverage of the whole room from the corner but with...

    v5.2.5 TLS support or upgrade

    Thanks for the link. The camera was supplied like this. Does this mean I cannot apply a chinese firmware without reversing the MTD hack (assuming this is possible)? Do you know if 5.3.0 supports TLS?

    Alternatively, Does anyone know if I can safely flash a chinese firmware on this with the language flag modified? Or is there a chinese IPC R0 firmware which supports TLS?

    Suggestion for a camera setup for pharmacy

    If you have the budget for a PTZ you can normally get 2-3 fixed cameras for the same money which will provide you better coverage/more angles.

    Suggestion for a camera setup for pharmacy

    It depends somewhat on the room layout, but in general fixed wide or fisheye cameras are better unless you will have an operator managing the cameras. Auto tracking PTZ cameras are normally not advisable in busy environments as there are too many possible objects to track.

    Suggestion for a camera setup for pharmacy

    Cameras that count numbers of pills etc are used in the process industry but cost a lot of money. Fitting any form of camera should be a deterrent however and you would expect to see a reduction in thefts because *most* people dont know how smart the camera is, only that they are being watched...

    Hi, I have a DS-2CD3132F-IWS running firmware v5.2.5. I have found v5.2.5 does not support TLS email support which I need for gmail notifications. The language flag is set to 1 however the serial of the unit has CH in it. DS-2CD3132F-IWS20150805CCCH533****** I assume this camera takes an IPC...
