FAQ's
Selecting the Right
Security Camera
Application. Ask yourself for what
purpose you intend to use a security camera or camera
system for: real-time viewing, store surveillance (which
means recording and storing video footage), one location
or several locations,
etc.
- Color vs. B&W. How important
is it to have camera images in color? Black-and-white
security cameras generally have greater sensitivity
at low light levels and thus are cheaper than an
equivalent color cameras.
- Indoor vs. Outdoor. If the camera is mounted outdoors,
be sure and get an appropriate enclosure for the environmental
conditions likely to be encountered. This can include
rain, snow, heat, cold, sun glare, humidity and corrosive
atmosphere.
- Fixed lens vs. zoom lens. Fixed-lens cameras are
much cheaper than zoom lenses. Ask yourself how important
it is to be able to remotely zoom in or out a scene.
- Fixed
mount vs. pan-tilt camera mount. Similar to the
lens issue, ask yourself how important it is to be
able to move the camera up, down, or side to side.
Note:
One pan-tilt-zoom (PTZ) camera can replace the
job of several fixed mount, fixed lens security cameras.
- Open
vs. hidden camera. Do you care if the security
camera is visible or is covert operation of the camera
important?
- Real-time vs. later viewing. Do you need
to be able to view camera images in real-time or
is storing images on a video recorder for later
viewing acceptable?
- Local viewing vs. remote
viewing. Do you want to be able to view images
from anywhere?
