Re: Running wire for security cameras, and tips on fishing wire?

["Bob Worthy" <securinc@xxxxxxxxxxxxx>]

The camera biz is starting to get diluted with wantabe's much like other
parts of the industry. The locksmiths, the gate fabricators, the audio
people are all in the market and the internet purchases make it simple with
no real training. I am just finishing a residential system that has (had) a
16 camera system. It is now a 15 camera system. The tele entry people resold
the owner on a little, I don't know what, camera at the gate. They
eliminated a small dome with telemetry zoom. The owner still wants me to
hook it up to the DVR. It is about 600' to the gate and they ran regular RG6
CATV
(aluminum braid) wire out there and with no power. I have two dedicated
power supplies for the camera system in the control room. The company plans
(until I talk with the owner) to power the camera at the gate operator. When
will people learn?
