Yes, these cameras work alright in the
cold. But if the plastic cover which is
over the lens gets wet or snow-covered you
will not be able to see a clear image.
Either you will have to make a shield to
cover the lens or place the camera under
the eaves or something. The cables on the
wired cameras are very thin and
unshielded. they are susceptible to rf and
other electrical interferance. The end of
the wire also has a phone jack connector,
which is susceptible to humidity and
oxidation. I snipped off the connector and
hard wired my cameras through terminal
blocks near the security computers. Then
ran RCA cables from the terminal blocks to
the DVR cards on the computers. As I said
on other threads, I also threw away the
garbage 12volt x10 power supplies and use a
computer at-style power supply to power the
cameras.
The x10 cameras are the crappiest cameras
out there, but they are alright for general
surveillance situations where large objects
like cars need to be tracked. For high
resolution situations, go elsewhere. These
things are very low-resolution CMOS
cameras. There are much better cameras for
not much more money out there.
