How far can I run a video cable?

[jtaylor]

There a bird house on the end of the dock about 100 ft away from the
cottage. I have a teeny-weeny video camera that'll run on 5volts and has a
standard video output, the sort you'd plug it a VCR.

If I run a cable out to the camera mounted inside the bird house will I get
a usable picture?

100ft is no problem, 300ft and you would loose a bit of quality.

But you should use good quality 75 ohm coaxial cable

Guess which has occurred.

Probably, you would have to use the right impedance coax, (75 Ohm).

Level and high frequencies will drop a bit, but for the birds... probably OK.

That could be a 75 ohm F connector or a baseband RCA jack. The
latter truly gets *plugged into*, but I'm assuming the former is
what the OP has.

Only if you can get an artist or photographer to draw/shoot you
running with cable

100ft is no problem, 300ft and you would loose a bit of quality.

Since *you're* definitely talking RF, you really can't make that
kind of generalization. RG-59 (~2 dB/100 ft., ch 3, 68 F), RG-6
(~1.6 dB), RG-11(~1 dB), and up to 1.25(~.25 dB) in hardline all
have different attenuations. Throw in a dB or so for f'd up
connectorization

If the OP knows his his output level...
