3.5. OSD (On Screen Display) Menu
An OSD menu is provided to display the status of the camera and to configure the functions
interactively.
The information such as Camera ID, Pan/Tilt Angle, Alarm I/O and Preset can be displayed
on screen.
3.6. Alarm I/O Functions
4 alarm sensor inputs and 2 alarm output relays are available.
To reject external electric noise and shock, the alarm sensor input is decoupled with a photo
coupler and the relay is used for alarm output.
The signal range of the sensor input is from 5.0 DC to 12.0 volts. The maximum load of the
relay contact is 250VAC/3A or 28VDC/3A.
If an external sensor is activated, a camera can be set to move to the corresponding preset
position. Meanwhile, the output relay can be matched to some specific preset positions to do
counteractions such as turning on a light or sounding an alarm.
3.7. Reserved Presets for Special Purposes
Most camera characteristics can be set easily and directly with a reserved preset, not
entering into the OSD menu. For more information, refer to "Reserved Preset" in this
manual (section 4.4).
3.8. Environmental Compatibility
Fans and heaters are built into the camera for cold and hot temperature environments. The
mechanical design protects the camera from water and dust. (IP 66).
