Hi Everyone In CCTV Land. If Only These Kind Of Forums Were Around When I Was a Teen!
I Just Bought a 4 Cam System. I Installed All Of It Including Running Underground Conduit.
Hiding Cables, and Making Use Of Short Runs To Componets. Sealing All Opened Cavities
In Regaurds To Cable Runs. I Have Perfect Coverage, and Reception. The Problem I Have Is
With The 12" B/W Monitor. When Turned On I Have Serious Hardcore Interference On My
Home TV (Not HDTV), but Not On My Home PC Monitor.
What I Know: The 12" CCTV Monitor Is Transmitting Not Receiving Interference. (EMI)
When The Power Button Is Turned On. It Is Not a Ground Loop Problem.I Plugged The
Monitor Into Any, and All Different Receptacles On Different Circuits. No Change.
What I Did: Used The Same Receptacle My TV Uses, and With a 100 Ft Extension Cord,
With The 12" Monitor Walked Away From The Area. As I Walked Further Away The Interference
Dissipated. 75 Feet Out, There Was No Interference At All.
My Question: I Have Heard That Building An Enclosure Insulated With Tin Foil Will Fix This Problem.
Is This True? If So How Thick Of Tin Foil Am I Looking At. If Not What Should I Be Looking For To
Fix This Issue? Any Good Links Would Be Great For Me To Learn More About This. I'm Never Afraid
To Learn Somthing I Know Nothing About. ~Wake~
It Is a Brand New 12" B/W Monitor Standard CRT, Not Flatscreen 100-230VAC, 50/60HZ, 30W, 1000 Line Res.

Wow!! Those Were Nice Articles. I Definitely Learned Something Here.
The Kicker Is That I Knew The Logic Of The Split, but It Took Me To Read The Tech Notes To Get a Better Understanding Of It.
I Really Appreciate That Scorpion. I Have Put In a Order For The X10 Pro Filter. Hopefully In a Few Weeks I'll Get It, and I Will Post The Effectiveness. Thanks! Again ~Wake~

I love finding those "nuggets" of information!
It is amazing how you can be at a loss on a project then all of a sudden one sentence can pull back the dark clouds, and let the sunshine in!
I do not suggest anyone buy those testers the XPTT, and the XPTR as they are extremely expensive. Great for the Automation full timer, but not for a one up use.

QUESTION: Why is there always enough time to go back and fix it right a second time??

Again, Thank You For The Information. Got The X10 Filter. The Filter Did Filter Out About Half Of The Problem. With The X10 Filter, and a Cardboard Box Wrapped In Tin Foil All The Interference Is Gone.
