7.2.4 Management
Through the management interface of the software, users can make various configurations of video images, set up
and manage various parameters, such as recording schedule and event trigger conditions.
7.3 Advanced Features
7.3.1 E-map
The E-map functionality gives users an overview of the system and helps them quickly locate each camera. When
an incident occurs, the related camera will be marked and the user can immediately switch to the images of that
camera (Figure 7.9).
7.3.2 Auto-backup
Auto-backup enables users to back up data regularly and automatically, providing a more reliable IP surveillance
system.
7.3.3 Failure Report
Failure reports that display a history of system errors can help users solve problems more efficiently.
7.4 Digital I/O Devices
Digital input and output ports connect network cameras to external security devices such as alarms and sensors,
strengthening the surveillance system’s detection and alerting capability.
7.4.1 Digital Input Devices
● Glass break sensor:
the device can detect specific frequency of sounds and vibration, for example, glass
breaking. It is usually installed by the window to detect glass window breaking caused by burglary.
●
Active infrared sensor:
the device emits infrared light to detect intruding objects. When the infrared beam is
blocked, alerting signals will be sent. It is usually used for outdoor applications.
●
Smoke sensor:
the device can detect dust concentration in the air. Mainly used for fire detection, the sensor
sends out alerting signals when the concentration of the dusts exceeds a given value.
●
PIR (passive infrared sensor):
the device can detect object movement by the infrared light emitted from the
object caused by its temperature.It is ideal for indoor use.
