hi everybody ! first, sorry for my bad english, i'm french and i do what i can i have a problem with a cheap CCTV configuration in my house. i have installed 6 CCTV cameras with rj45 cable and balluns, a dedicated power supply 12V 150W and a digital recorder for CCTV with a lan access and a 2To hard drive... when i have installed all of that, that was perfect ! good captures and no parasites. but after 6 months.... argh ! can you help me to solve this problem ?

i have does the test with a new power supply only for the dvr... it appears better. i'll look during a week if it's constant.

but when i plug them on a tv, no parasites... if it's the power supply, they should be here (the tv, for the test, is near to the vcr in a special 19" bay without sector parasites, same as all cables and 12v power supply for cameras and vcr)

i have ettempt many test today: change pal to nstc => the screen jump change quality while desactivate many cameras and level up quality and framerate on only one camera => no change remove the fan inside the vcr (maybe it cause parasites) => no change remove the hdd (power supply + sata) => no change plug only one camera => no change when i plug a playstation 1 to the vcr, nothing appears (maybe too high resolution...) when i plug a camera to a little 36cm TV, camera appears with a great quality ! my problem appears to be the recorder... but 100€ in the wind ... argh !

on the vcr ?
