Chapter 1 Overview
1.1 Brief Description
Thermal & Optical Bi-spectrum network camera equipped with built-in GPU which supports
intelligent behavior analysis algorithm, can realize high-precision VCA detection and real-time
alarm. It is applied to perimeter defense and fire-prevention purposes in critical infrastructures
such as community, villa, construction site, factory, 4S stores, and so on. The pre-alarm system
helps you discover unexpected events immediately and protects your property.
1.2 Function
This section introduces main functions of the device.
Note
Not all models support the configurations below, take the actual product for reference.
Fire Detection
Device can detect the dynamic fire source in the scene and output pre-alarm and alarm to protect
the property.
Temperature Measurement
Device can measure the actual temperature of the spot being monitored. The device alarms when
temperature exceeds the temperature threshold value.
VCA
Device can do behavior analysis. Multiple rules can be configured for different requirements.
Smoking Detection
Device can detect the smoking behavior and alarm.
Power Consumption Mode
Device supports low power consumption mode and sleep schedule to reduce the power
consumption when the device works.

Chapter 3 Temperature Measurement
When you enable this function, the device measures the actual temperature of the scene. It
alarms when temperature exceeds the temperature threshold value.
3.1 Notice
This part introduces the notices of configuring temperature measurement function.
●The target surface should be as vertical to the optical axis as possible. It is recommended that
the angle of oblique image plane should be less than 45°.
●The target image pixels should be more than 5 × 5.
●Please select line thermography or area thermography for a certain area temperature
measurement. The point thermography is not recommended in case of deviation occurred
during device movement to affect the accuracy of temperature measurement.
