ELECTRIC CONNECTORS AND RESTORING FACTORY DEFAULTS
4.2 PIR function
Passive infrared (PIR) detectors are widely used, including in alarm systems for motion detection. The
operation of the sensor is based on the precise measurement of the temperature of objects in a specific
area, and each change of this temperature is interpreted as motion by integrated electronics. The task of
the PIR detector in the camera is to limit the number of false motion detection alarms.
The PIR detector, working in conjunction with the motion detection function, detects moving objects
with a temperature higher than the ambient temperature. It is only the simultaneous detection of motion
by the PIR detector and the motion detection function that generates an alarm event. In this way, the
PIR sensor significantly reduces the number of false motion detection alarms related to light flashes,
snowfall, insects or day / night switching.
5. ELECTRIC CONNECTORS
5.1. Connecting power supply to the camera.
Camera can be supplied using external power supply unit corresponding with the camera parameters or
by using RJ45 network socket and PoE (802.3af) power supply unit.
Information:
Power supply adapter is not included. Please use power adapter with parameters specified in user
’
s
manual.
WARNING!
It is forbidden to use –
as the camera power source –
PoE equipment (adapters, etc.) not
compatible with IEEE 802.3af standard (items called
“
passive PoE power supply
”).
Damages that
results from the usage of improper power supply source are not covered by the warranty.
WARNING!
In order to provide protection against voltage surges/lightning strikes, usage of appropriate surge
protectors is advised. Any damages resulting from surges are not eligible for service repairs.
6. RESTORING FACTORY DEFAULTS
6.1. Restoring factory defaults
Camera allows to reset its settings to the factory values. To restore the camera settings to the default, go
to the
"Load Default"
tab (Remote Setting
-
> Advanced
-
> Load Default). Then select options and
functions of the camera whose settings are to be reset and press the
"Save"
button. After about 30
seconds, you can re
-
connect to the camera (at the current IP address, as long as it was not reset network
settings or on the default IP address).
