A quick update on this issue.
I checked the day's footage last night and found that at almost every instance where a person moved across the scene, the image would break up and the person would have a "digital" trail for the entire width of the image.
It appears that lowering the bit rate did not resolve the problem.
I did find by accident that when I reviewed the same recorded footage on my Ipad using IVMS4500, there was no corruption.
Based on the image in the first post,
@flyinghack appears to be using IVMS4200 for playback which is exactly what I'd been trying.
Looks like the problem could actually be with IVMS4200 decoding the image rather than any issue with the camera or network.
Hi,
The ghosting / trailing is generally noise reduction, I run my G2 Acusense at 40% noise reduction because of this. Also If anyone else is having issue with image quality and the freezing on motion for this camera see my other post.

Also, disable WDR and set your exposure to 1/50 minimum. A General rule is, all the "digital" enhancements will ultimately make your image quality worse. Sometimes you need a little WDR or black area depending on the scene but if you can avoid using these settings please do.
Also people often mistake FPS for shutter speed, if you want sharp images you need to lower your exposure time. You could run 2 fps with 1/750 exposure and capture number plates all day.
Also please note that the "exposure" setting in the camera is a minimum. Because of this do your testing in bad lighting so it sits on the minimum set exposure so you can get an accurate result. Eg full day light may force the camera to 1/1000 which will yield tack sharp number plates but if it's cloudy and it falls back to the minimum you set "1/50" you may find you now get motion blur. Once it's really dark and the camera has to turn the ISO up you will now get noise in the image will further reduce the quality.
If you need to capture number plates at night you will need probably at least 12mm lens looking at the street ideally less than 20%. You will have to turn the shutter speed to at least 1/250 - 1/750 depending on the road speed.If you manually set your camera to "Night" or set a schedule for "night" you will now get the gain controls under the exposure section. For your camera do not go higher than 40 on gain. You will expect the image to be nearly pitch black at this point. You will get a sharp clear number plate in any weather condition with these settings. please see attached example photos.
If you need help getting number plates please PM me and I can explain further.
Example images are with following settings: Your camera will not be able to do this as it needs to be a tighter lens, say 12mm and also you will need longer IR range at your distance.
Mode: Night 24/7 (If have other cameras that can get the color if needed) IR mode is more forgiving during the day with shadows and light changes ETC.
Gain: 30
IR: 80M 100%
Exposure: 1/750
Noise Reduction: 30 (Removes Ghosting)
Digital Enhancments: Off
I Frame: 50 (They say match FPS but I leave mine at 50 because default)
BitRate Type: Constant
Res: 8MP do not go below 6144 bitrate, 8MP does need a fair amount of bandwidth
SpeedZone: 60 kmph (tested at 110 same settings)
