  1. Thanks for that, I switched to OSD Color and the flickering is over now.
  2. Getting dark my IMX291 NVP2441 switches for tens of minutes between the color or BW mode. Can I prevent/manage that problem with the OSD Settings?
  3. 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?
  4. As much as possible I like to use my 12v 40A power unit for powering the Poe based cameras and the DVR/NVR both. Can I safely connect my China based H.264 DVR/NVR by Cat 5e to a 12V Poe Switch or could that damage the DVR/NVR? The DVR/NVR will be powered via the standard plug.
  5. The DVR has only 4 fysical connections but it can handle more IP based cameras at the same time. Then you would need IP cameras, not AHD cameras with baluns. Thanks for your clear and helpful answer
  6. The DVR has only 4 fysical connections but it can handle more IP based cameras at the same time.
  7. 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.
  8. That's what I was afraid for... My DVR My cams If so...buying replacement IP based camera boards might be cheaper...
  9. I like to bring in a third DVR in a local network but the router has a limited number of LAN ports. Would that work with the two switches in this scheme? Is it possible to use a single videobalun to create "IP camera's" (as the DVR can handle more IP cameras then standard camera's) ?

    Diagonal pattern on CCTV camera

    You're right! My interference problems were solved at the moment the DVR, the PTZ and all the other camears were connected to one and the same power adapter.
  11. 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.

    PAL NSTC UTC

    Being on spot, I turned my DVR temporarily to NTSC instead of PAL to get entrance again ..et voila!
  13. 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?
  14. 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.
  15. Thanks for that! What does it make better, possibly less video and sound interference problems?
