Ghosting blurred motion footage at night

I'm experiencing poor nighttime footage on my hik 5mp cameras. The footage of people looks ghosted and blurred. Overall extremly poor my settings are

2560x1920 resolution at 12.5fps
Shutter speed 1/50
Colour vu light on auto and brightness is 50
Wdr set at 15
H265+ encoding max bitrate 3000kbps, max average bitrate 2000 kbps
Contrast and color all default values of 50

I have attached a video which hopefully shows the issue. Is there any settings that can improve this please?

are you using NVR/SD card or blueiris?
modelnumber of cam ?
why are u using wdr in such a scene?
is 12.5 the maximum fps what is possible ?


can you post settings screenshots ?


all in all: 5MP colorvu... sounds like 1/3" ... which will end in this

I will answer this the same way I did previously. A shutter speed of 1/50 is too slow for blur free video. The slowest at night is 1/60 and 1/100 will result in even better video. If increasing the shutter speed produces too dark an image you can play with gain and exposure compensation as well as brightness and contrast. If that doesn't work the only other solution is to add light, either visible if you're trying to maintain color at night, of IR if you're working with black and white at night.

Every camera needs light to "see" just as humans do. The sensor size is critical to produce good night time video. A 5MP camera will need relatively large sensor. Look at the chart below. This is the best combination of resolution and sensor size available today. What size sensor is you 5MP camera?

1/3" = .333" 720P
1/2.8" = .357" (think a .38 caliber bullet) 2MP
1/1.8" = .555" (bigger than a .50 caliber bullet or ball) 4MP
1/1.2" = .833" (bigger than a 20mm chain gun round) 8MP

Hi I am using an nvr. I can increase the frame rate to 20fps but that means reducing the resolution to 4mp

Should I turn wdr off? Sorry I am a complete novice here

The sensors is 1/2.7" Progressive Scan CMOS. Is this too small?
 
For a 5MP camera a 1/2.7" sensor is too small. That sensor is ~.370" in diameter, slightly bigger than the right size sensor for a 2MP camera. You're 5MP has to and a half times the number of pixels on the sensor. The result is that it needs almost two and a half times the amount of light to "see" at night than a 2MP with the 1/2.8" sensor. A 5MP camera would need a sensor of 1/1.x or so to produce the same video in the same light conditions.

Changing frames per second, resolution or bit rates will not solve your problem.

Thanks for that much appreciated. They are color vu cameras so not sure of that will help with light
 
can you please post model number and settings from cam interface , not nvr

They are hilook ipc-t259h 5mp cameras with colour vu

The only settings I have changed are exposure time to 1/50 wdr to 15 everything else is default.

Reading some of the other replies I think I should have gone for proper hikvision cameras. These hilook ones are aimed at domestic users as opposed to professional installers
 
its hard to help you, we all have no clue of possible menu settings, we dont have the cam.

i just can say that @sebastiantombs is right for sure, but i have some dahua 8MP 1/2,7" , which have better picture in same light condition than the first pictures...

FPS / BITRATE / SHUTTER / GAIN / etc. .. can help... but it will not give you near good picture than with any bigger sensor camera...


maybe better to buy new/better cam instead of wasting any time on it

Thanks for the help much appreciated. I think I'm going to bite the bullet and just the profession hik g2 cameras
 
Keep in mind that ColorVue, FullColor, Starlight, Starlight+ are all nothing more than marketing terms designed to sell a product. There is no "standard" for any of those terms and they can be applied to an 8MP camera on a 1/3" sensor which will be basically blind at night. You're best served with using know, good, brands and only paying once rather than buying an hyped, by the manufacturer, camera that won't perform or allow proper setting of all parameters. As looney2ns says "buy once, cry once".

Also i suggest you to buy a IR camera, there is more options to get better picture with IR mode when having not much light than with white light..


colorvu with 4mp 1/1,8"

DS-2CD2347G2
DS-2CD2T47G2
DS-2CD2047G2

hikvision has no ir model with 1,8" and 4 MP (or i dont know about it) ... so you have to buy dahua... but if you like colorvu at night, you can buy them... (but you can also set forced color on any dahua... maybe you will have a bit better picture with hikvision, read reviews about it)

What fps and bitrate do you use on your 8k dahua please
 
I was going to guess that given the amount of light in the scene at 1/50 on a 5MP a 4MP on a 1/1.8" would be able to stay in color at night. user8963 gave you the Hikvision models. The Dahua 5442 series, turret and bullet styles, are the equivalent. Dahua also has just released an 8MP on a 1/1.2" sensor that has IR for low light.

Thanks for the reply the light in those scenes seems overly bright as the colour lite is enabled. Without the light the only lighting comes from some street lights that are beyond the field of view

i have one at lower megapixel with 20fps and another with 15fps ...

the problem with my 8mp cameras is, they cannot run everything ... because the cpu is so crappy... so you have to decide between fps, smart codec, ivs ... otherwise you will have to much dropped frames. i am fine to run it at 15fps , no problem... with fast shutter you should get at least 1 identify picture/frame.... but just try it... it has no effect on light...

night settings are not helpful for you, because it is a IR -camera ... so i can run it in bw mode with ir light at lower shutter speeds... but the nightview is awful comparing to 4mp 1,8" (but not much motion blurr as reolink, so you can identify somehow). they are used as indoor cameras.

also first try without wdr/blc/...

also what you can try... do not use smartcodec... you might get a better picture without it...
