The cost of this system
is around $175 on eBay with microphone, a couple mounts, battery holder and
microphone.

Addition
note: these cams have 3x digital zoom and variable brightness via
optional plug in remote control.
At first glance you
might say these specs look just like the Viosport… maybe so but not all
cam’s (or CCD firmware) are created equal – read on.
The good:
-
Low cost.
-
Reasonable video
quality.
-
Optional remote
can adjust for bright or dark situations.
-
Excellent audio.
-
Excellent indoor
video quality.
-
Packaging is
minimal, an environmental plus.
The Interesting:
The Bad
-
The color of the
image is “flat” or “gray/blue” outdoors – not vivid, like one would prefer.
-
Complicated/messy
wire harness with multiple adapter plugs/wires makes it bulky.
-
1/4x20 thread
mount on back of cam instead of top or bottom.
The Ugly
CONCLUSION:
**UPDATE: January 6, 2007: I was sent a
couple "gel" (plastic) balancing filters by the nice folks at QVC video,
essentially these were neutral density balancing filters - they tone
down the image in bright conditions. They did just that but did not help
the color saturation or contrast issues, so my below opinion stands.
VIDEO: Really
if they could adjust the image color balance for OUTDOORS instead of
indoors this would be a sweet deal for the cost. Well, being primarily a
security camera I guess you would expect this. That is probably why the
outside video is blue/gray and the indoor balance is excellent. Clarity
is good, so I give this cam a 6+ or 7 for outdoor video and 9+ for
indoor.
AUDIO: The mic
on this system is on a separate line allowing you to place it just about
anywhere you like. The quality is EXCELLENT but with two complaints.
First is that the mic is just plugged into the end via a small
electronic terminal connector, you need to shrink wrap it or tape it on…
or you will lose it! Second the wire harness, made for the security
industry, has many bulky adapters and wires to get you to your recording
device. (RCA to composite 3.5mm plug for example).
IN
THE SHORTS:
If you are on a budget
this system is OK. It will certainly get you some OK video, the color
balance is the biggest issue. You can do some color correction in the
post video editing, but that will only get you so far. This system: A
fair value.
WHAT
I WOULD CHANGE:
-
Color correction
for OUTSIDE light conditions.
-
If these “generic”
systems insist on having RCA plugs, include a very short RCA to
3.5mm composite adapter cable. I ended up soldering my own together.
-
Include plastic
spiral cable wrap to configure/clean up your cables.
