ColorVU Video Settings?

I currently have the below cameras but struggling to get the video settings right.

If I up the bitrate the footage becomes too laggy and really struggles with people in picture. I also thought I would get better face detail than I do? I will post some pictures and also the settings.

I have downloaded directly from the DVR and I still don’t see faces at night as I get motion blur?

Front of house (4MP ColorVu)
DS-2CD2347G1-LU 2.8mm

Back of house (5MP Colorvu)
DS-2CE72HFT-f28

DVR
iDS-7204HUHI-K1 / 4S(B)

Is this the best I can get?

Hi @Jfd7000

Can you share screenshots of the image settings for both these cameras?

By default most of the ColorVu models come out of the box with their exposure time/shutter speed set to 1/12, this is slower than most IP cameras because the slower/longer exposure time allows more light into the camera so you get brighter night images. The downside of this is that the long exposures cause motion blur in moving objects like people and cars which can distort small details like faces, if they are set to 1/12 (or similar) we would recommend raising the exposure to 1/25 (1/30 if you are using 60Hz).

You can potentially speed the exposure up beyond this but the shorter the exposure time the darker the image becomes, so it is a bit of a balancing act to find the sweet spot for your conditions.

Thanks Dan yes I will post some more pictures and settings. I’ve reset the 4MP settings because I had changed so much. The shutter speed was 1/12 so I have changed this now to 1/25. At the moment the backlight settings are off. To get a lighter image at night what do I need to experiment with the BLC, WDR and HLC settings? I noticed when I reset the camera it took the other settings back to h.264 so I have changed this to h.265.

WDR & HLC will probably be the ones to have the most effect on your scene because they balance and reduce the brightest parts of the scene, so in your case, that would be the reflection off the road and the streetlight lamps visible in the cameras FoV.

I can't really give you exact settings to try because settings will vary for every scene and it is just trial and error to find the settings that give you the best results.

Ok thanks Dan so the picture seems ok but when people are walking past or cars going past on playback they freeze and kind of stutter. Will this be the bitrate? Ive turned this down now.

Hi Dan, I have reset the 4MP Colorvu camera to default and experimented with some settings. I found if I increase the bitrate settings when cars or people go past they freeze for a second or two so quite jittery. I have attached the current settings and an example picture. I will post a daytime pic when it’s light. Thanks for your help.

@Jfd7000 i have the same model of colorvu and am trying to optimise my picture as well. For your front cam try BLC top or bottom, after making the change wait for the image to adjust itself. My playback is problem free, I’ll post my video settings tomorrow.

Thanks appreciate that.
@Jfd7000
Camera DS-2CD2347G1-LU
Firmware V5.6.5 build 200316

I use IVMS-4200 (Windows) for remote configuration. Image settings are changed at the camera interface.

Always check live view and playback using the NVR and local monitor. WiFi connected devices can give live view and playback problems.

These screen shots are settings of my LED light, video and image night schedule and give me excellent body face pictures (4m) and car reg plates (8m headlights on).

Image day settings are HLC off and exposure 1/250.

The brighter screenshot is HLC off.

Great thank you. What does the Image day settings are HLC off and exposure 1/250 mean sorry? Your screenshot says 1/100 and HLC is on?

So night is selected but the time is from 7am to 6pm?
Sorry for the confusion. Night timing is 18:00 to 07:00 and Day times 07:00 to 18:00. When you click on the Day or Night buttons you can adjust the image settings for each. During the night timings HLC is on and exposure increased, day time HLC is off and exposure reduced.

Great thank you David. I noticed you have h.265+ enabled. How has that been for you?

5 of my cameras use h265+ and I’ve never noticed any problems.

if you use image day and night schedules you my have to adjust the schedule times as the daylight gets longer/shorter.
