In my humble opinion what IanMK would like to achieve (decent face/body recognition at night) requires either a specific camera or much more light. Would an additional IR lamp make any big difference? Btw:In my case WDR was a real game changer. The situation improved but there is still a huge...

Hi both, I played around with WDR again. I realized that setting it "Auto", the results were really poor (I'm actually not sure if the camera was able to turn it on). I set WDR to "ON" and the result dramatically improved (the quality is great also at night). Now I still have a problem with two...

Hi all, thank you in advance for your help. I have a few Hikvision cameras in my garder that are doing great during the day. Unfortunately, for two of them I have some challeges at night. They cover a very wide area and the built-in IR is not powerfull enough for my needs. The items that are far...

Update: "drop the I-Frame interval to match (or go below) the camera's frame rate" as discussed the I-Frame interval is automatically managed by the camera. I cannot change it. Anyway the camera chosed to set it at 15. I'm recording at 12 frames per second, so we are not too far from your...

Hi StewartM, I realized that using H265+ the I-Frame interval is automatically managed by the camera (this was described in a post from Phil).

Phil and StewartM: Thank you in advance. I will play around with the settings you suggested. Just a very basic question: The I-Frame interval is greyed out, any idea on how to change it? In the meantime I run test with a plain paper in from to one of the DS-2CD2185FWD-I camera (the one using...

Andy idea? Thank you in Advance mc

Hi, the fixed DS-2CD2185FWD-I cameras are 2.8mm. The DS-2CD2785FWD-IZS is a varifocal and I configured it "closing" a bit the lens, like it was a 4mm. I took a picture in different moments of the day (so with different sun and shadows). The files are all 3840x2160 with 96dpi and 24 bit depth...

Hi folks, I upgraded all the cameras with the latest available firmware (build V5.6.0) I downloaded and analized a piece of video recorded on the SD of bot cameras. Both DS-2CD2185FWD-I and DS-2CD2785FWD-IZS generated video in .mp4 format. Both are coding as MPEG-H Part2/HEVC (H.265) (hevc)...

Any suggestion from anyone? thanks in advance

hi, I attach the streamsettings for both cameras. The only difference I notice is that 2785 (which is working well) has an additional session related to the sound settings (which I'm not using). All the rest looks pretty the same.

Hi Phil, thanks for your follow up. None of the those features are configured. I double checked the configuration menu several times and there are no differences at all. The 2785 (which consumes less memory) has additional features related to alarm triggers/in/out/voice but I didn't enable them...

Hi, and thanks a lot for your suggestions. I upgraded the firmware to V5.5.83 build 190221 on both cameras. The codec version is V7.3 build 190124. I formatted the SD cards and reboot the cameras. Now, after 2h, the DS-2CD2185FWD-I has written 7,5GB of data while the DS-2CD2785FWD-IZS just...

Hi all, I own a DS-2CD2785FWD-IZS camera and four DS-2CD2185FWD-I cameras. All of them have the latest firmware installed. I inserted a 64GB SD card in all of them (same brand, type, size etc.). The DS-2CD2785FWD-IZS is able to record 3weeks of video, while the four DS-2CD2185FWD-I can record...
