Commissioning DDF5(X)00HDV-DN-IM
NOTICE
The DDF5(X)00HDV-DN-IM is exclusively designed for indoor instal -
lations.
An outdoor installation is prohibited and may result in malfunction,
damage, data loss and loss of warranty.
Operation
• When using a separate power supply unit, interference caused by a ground
loop may occur in the analog video preview signal. In this case, use a video
signal transformer (balun) for galvanic (ground) isolation between the signal
source (camera) and the RG-59 cable.
• In order to prevent damage to the device, a galvanic isolator (balun) must be
installed if the BNC interface is permanently in use.
• If the device or the cables connected to the device are located near sources
with strong radiation, the video image may be distorted.
• The device is equipped with automatic gain control (AGC). In low-light condi -
tions the image may be altered (e.g. noise). This is not a malfunction.
• The quality of the video image depends on the lighting conditions and the used
monitor.
• The accuracy of the automatic white balance (AWB) algorithm depends on the
used lighting. Mixed light (consisting of artificial light and daylight) may cause
color distortions (inaccurate color reproduction).
• Poor lighting can lead to an incorrect white balance.
