CCTV System (questions)

[buzzwhite7]

Hi,

I've just installed a new CCTV system using some ZXTECH cameras. I have powered the cameras using a Mini TP-Link POE switch and two power adapters. The cameras are as follows;

2x dome POE cameras

1x IP camera, not POE

2x small IP Cameras, not POE

The cable run to each camera is around 25 meters to 50 meters. The mini switch powers the two dome POE cameras fine. I have used a TP-Link power splitter to power one of the small none POE cameras (http://www.tp-link.com/en/products/details/cat-4794_TL-POE10R.html). And then two cheap passive power splitters from ebay with two power adapters to power the remaining two non POE cameras. This has all been connected using Philix CAT5e UTP cable from screw fix.

The problems/questions I have are:-

The two POE cameras work fine, but all the others flicker badly at night, Why is this?

Is it safe to power a non POE IP camera using the TP-Link power splitter?

Is it also safe using passive power splitters with the PSU adapters and then powering cameras outside the house, at the end of the garden on the garage wall. If a shortcut in the cable happened could this cause a fire or will the power adapters just blow.
The two adapters I brought are;

Power the none POE camera (40) meters night range

Power the small POE camera (20) meters night range

And finally, my last question - Is the cable I have used OK for use as POE cable or should I have used Plenum cable?

Any help or advise would be much appreciated.

Thanks in adavance

I'm looking to do the same but can these ip cams be set to record to a NAS like the more expensive Ycam.
Having already 2 NAS drives running I don't really want to purchase a DVR
