Camera Installation & Tips
The following provides general guidelines for configuring stationary and Pan Tilt Zoom (PTZ)
cameras.
•
The ioiboxes only support analog signal and the Video Input of the TRK
unit white balance signal should be 1V p/p
•
Connected video should be live when the TRK-unit is powered on.
•
If the camera model supports Onscreen Displays, these displays should be
disabled.
•
Analog PTZ cameras must have auto-focus. Assure that the camera auto
focus (AF) is enabled and manual focus (MF) disabled.
•
For PTZ cameras, if the camera model has an automatic backlighting
feature (BLC), disabled it.
•
Position the camera as best possible to avoid scenes that directly view the
sun at periods of the day.
•
On cameras that have extendable sun shields, extend them as far as
possible – this increases the possibility of the sunshield protecting from
effects of the sun and the lens from dust and weather.
•
If the camera model has image stabilizer functionality, it should be enable.
•
If the camera has built-in motion detection, disable it
•
If the PTZ camera model supports privacy masking features, all privacy
masks should be disabled.
•
If the PTZ camera model has proportional pan and tilt, it must be disabled.
•
If the camera has OSD, they should be disabled.
•
If the camera model has a shutter speed setting that is automatically
reduced during night, disable this functionality.
•
The camera should be adjusted for clarity of the objects and not
necessarily the best aesthetics. Adjust the sharpness, brightness, and gain
(on the camera itself) should be optimally set to this effect.
•
Adjust the focus as follows:
o
For all cameras, adjust the focus during the day to best view of the area
of interest. Final focusing always during the night
o
For day night cameras that have two camera, adjust each camera for it
day or night application to best view of the area of interest
•
For the lens of the camera:
o
Many standard cameras lenses automatically filter out infrared during the
daytime. If you are using a camera working with infrared illumination that
is a “night” camera, select a lens that doesn’t filter out infrared. Use a lens
that compensates for daytime infrared but supports infrared at night.
o
Choose a lens that provides sufficient field of view magnification, so that
the intruders can be detected at the depths required for the site. Note the
greater the magnification the less width in the field of view.
