Bad video on brand new CCTV, why?

[sz00gun]

Hi, I bought this CCTV:

• 4 Hikvision Turbo CCTV DVR 1080p HDTVI Mobile HD Video Recorder *NEW*
• HIKVISION Full HDTVI 1080p 2MP CCTV CAMERA SECURITY Outdoor 20M DS-2CE56D1T-IRM
• BNC RCA Cable Wire DC Video Power For CCTV Security Camera DVR 10M
  
• DC 12V 5A Power Supply Adapter For CCTV Camera + 4/8 Way Power Splitter Cable
  

At this moment I have all default setting, I'm working on 1024 Full HD, however 720p resolution makes the same problem.

This is a sample video: https://www.dropbox.com/s/xpfj9ptrpj69ry1/192.168.0.13_01_20160428221951491.mp4?dl=0
Another bad video: https://www.dropbox.com/s/n8g8cytlob8l2w1/192.168.0.13_01_2016043014144241.mp4?dl=0

why I can see these artefacts/pixels?

Any idea?

Maybe it's just me but your video link doesn't work. And bare in mind you don't really have a high end setup. So video quality will be lacking no matter what

Thanks @badmannen, video links are working. Please have a look again. Maybe this is no the best hardware, however some videos with the same CCTV on youtube are much better than mine... So thinking where is the problem?

 

[badmannen]

Can you decrease gain? And increase digital noise reduction? ( not sure if you got those settings with your hardware)

I would try a different cable...often low quality premade cables cause issues..also if your cable is rolled up for testing, try laying it out straight, it may be causing interference with itself..

Thanks badmannen and fenderman, settings I have: http://s32.postimg.org/ovzd0nmkz/vid.png

so you both think there are more cables issue than hardware/settings?

I try buy better quality cables, but there aren't on ebay... all looks the same, the seller never had that problem before - this what he said...

 

[badmannen]

Just try moving the cable and twist it a bit. If the image is changing while you do that it means one thing. It's a shitty cable ... Or even worse could be lose connection at the camera side... Anyway.. Hardware problem if this is the case

Moving/touching cables doesn't help with my issue... For some reason sometimes is better sometimes is not... weird..

 

[badmannen]

No I didn't mean that would fix the problem. It would at least get you closer to where the problem is

HDTVI cameras require high quality rg59 copper cable, not cheap pre-mades. I have these cameras and tried with cheaper cable, image quality was terrible but not same issue as yours. Not 100% certain it is your problem but most likely, different cables create different problems. That seller certainly tested the cables on low resolution analog cctv cameras, not HD TVI. These cables are not suitable for TVI.

The best way to do it is to buy your own 100% copper cable/connectors but its not easy. There are also better quality pre-mades such as http://www.ebay.co.uk/itm/PRO-COPPER-RG59-BNC-Video-SECURITY-POWER-SHOTGUN-CCTV-CABLE-10-20-30-40-50-200m-/371465614067?var=640522947817&hash=item567d1372f3:m:mewUJVvqzBkUgzUp2uboiEg These are likely not 100% copper but rather copper clad steel(ccs) but will be good enough for a high quality picture with minimum anomalies.

Thank all, I just bought the cables mentioned before, hopefully be better now I will let you know later

Don't know about the power supply since you did not provice the right link, but those cables are sure crap...

Curious, why would you buy TVI over IP system?
