How long can
a camera record for?
The amount of recording time is dictated
by your recording device. A standard VCR
can record for up to 10 hours if a T-200
tape is used. We also offer long play
recorders that will record for 24 to 960
hours on one tape.
What do
resolution & lux mean?
Resolution measures the cameras ability
to reproduce an image. The higher the
resolution, the better the picture
quality. Lux is the measure of light the
camera requires to reproduce an image.
The lower the number the less light the
camera requires to reproduce an image.
What does FPS mean?
FPS (frames per second) the number of still frames (pictures) that give the
illusion of motion, which appear in a single second of time. 30fps is considered
"Real Time". So for Real Time viewing of your cameras, you need at least 30fps
for each camera.
Can I zoom in
with a camera?
Yes, but you need a special camera (PTZ) with that functionality built
in. Compare to fixed cameras they are more expensive.
What camera lens size is the best for my
application?
It is recommended to use an auto-iris lens when light conditions
vary (EX: outdoor cameras).
Wide-angled lenses (EX: 3.6mm) are better for viewing a general
areas.
Narrow-angled lenses (EX: 6-8mm) are better for looking down
hallways or at cash registers.
What is CCD?
It is analog technology. The CCD camera has a little bit higher resolution
than CMOS. The camera also functions better in low light. A CCD camera drains a
little bit more power than the CMOS cameras. It uses 12v instead of 9v. CMOS
camera is smaller than a CCD camera and works longer with the 9v battery.
