    Getting dark the image my IMX291 NVP2441 camera board gets more and more purple coloured.

     

    From my part it could turn to BW now. Can I adjust in OSD the moment it start to turn to to BW?

     

    It it possible to prevent in OSD the purple coloration too?

    Hi. Your best option is to spend money on replacing dvr.

    You will only be wasting money adding IP to a cheap dvr

    Your camera link is to 4 in1 camera modules which supports CVI so just buy a 32 way or 2 16 way cvi hybrid DVRs.

    No switches needed

    For sure, 16 or 32 way realtime 25 fps would be great!

    Given the budget limitations, working with CMS, switches and several DVR's is considered to be a good alternative.

    IMX323+HI3516CV200 based IP modules are not that expensive compared to the boards already used but I have have to deal with the already available infrastrcuture too.

    I dont think its that simple. Im not sure what device you have your AHD cameras connected to. You need some type of converter device like this

    https://www.amazon.com/Axis-Communications-0415-004-4-Channel-Encoder/dp/B0074ANCMW/ref=sr_1_1?ie=UTF8&qid=1499017434&sr=8-1&keywords=ANALOG+TO+IP+CONVERTER

    But be aware that it only provides you with one IP output. So the 4 cameras would be combined to into one camera channel.

    Also, your DVR is for 4 channels, so will the software allow you to see more than 4 channels?

    Dont know alot about this, hopefully someone more knowledgable comments.

     

    That's what I was afraid for...

    My DVR

    My cams

     

    If so...buying replacement IP based camera boards might be cheaper...

    Anybody who knows if an AHD-H module block will work in and "old styled" PTZ unit?

     

    Yes it will...just make sure you connect the ribbon cable in the right direction

     

    In addition to that I learned that connecting my H264.DVR with this AHD-H PTZ camera only gave the choice 1080P if .....on beforehand I connected another AHD-H camera with this 4 channel AHD-D DVR. I can't explain but it is good to know...

     

    This week I learned that a ground loop was the reason far all the difficulties I had. At the moment the DVR, the PTZ and all the other camears were connected to one and the same power adapter, all the problems were solved! The PTZ works flawlessly and I have zero video and sound interference.

    Was playing around with the UTC based settings on my AHD-H camera (on a remote computer connected via internet to my H264.DVR).

     

    I turned on NTSC instead of PAL ....and my screen turned 100% black, stupid me!

     

    Is there any change to get my PAL setting back?

     

    Being on spot, I turned my DVR temporarily to NTSC instead of PAL to get entrance again ..et voila!

    Hi Bubo

    >Make sure you have no interference

     

    I have tested with 3 Kameras and different power adapters . Still Motion detection permanent. Thanks for your Settings,but what are the different to mine ?

    Axel

     

    The tiniest interference could spoil your motion recordings....make sure it's completely free of interference (at dark).

     

    Make sure the sensivity is set to "the lowest".

     

    Try a region as small as possible.

    Having an AHD-H DVR and plenty of RG59, Cat5e and shielded audio cables, I'm wondering what would give the best image quality and sound given a camera distance of 40 meter

     

    1. a separate RG59, a separate shielded audio and a separate power cable to the camera and the microphone?

     

    or

     

    2. two passive 4 channel baluns and one Cat5e cable (for power, video, audio)?

     

     

     

    Ps: could RS485 be added to the Cat5e cable too?

    Hi, i have the following dvr

    https://www.aliexpress.com/item/Super-New-8CH-AHD-DVR-AHD-H-HD-1080P-Video-Recorder-H-264-CCTV-Camera-Onvif/32694457119.html

     

    and this AHD Camera

    https://www.aliexpress.com/item/New-Product-HD-1920P-Outdoor-Surveillance-Array-infrared-Security-AHD-Technology-3MP-CCTV-Camera-With-Bracket/32515712107.html

     

    but i get motion detection not to run. The dvr record permanently without interruption. can someone help me?

    as i enabled Motion detection the dvr records even if no movement is detected. what could be wrong?

     

    It looks like the menus of these unbranded dvr's all look the same.. the start is the hardest

     

    How about:

    SETTING-RECORD-RECORD

    Record mode :timing

    Week: all

    Period 1: 0-24

    Regular: blank

    Detect: x

    Alarm: blank

     

    SETTING ALARM VIDEO MOTION

    channel: 1

    setting: 0-24

    record channel: 1

    Working my unbranded AHD-H camera I noticed at the right side of the birds some "aureoles" and shadows"

    As the time of registration is to short to make any OSD adjustments at that moment, I would be pleased to know what could/should be adjusted...

    Any idea?

    Had the same type of interference, driving me nuts as it was registered as "motion". Working with an inexpensive unbranded Chinese 1080P H264.DVR and a similar AHD-H camera, I learned that I had to use another power supply (not to work any longer with a splitter and a joined adapter). Even more more important was plugging in an audio in cable.
