en | System Overview
Power-over-Ethernet (PoE) allows to use the Ethernet cabling for data transmission and for
supplying power to the network device in the same cable. It is possible to realize long cable
lengths in a PoE network system. The standard power supply for the video-based fire
detection is Power-over-Ethernet. Alternatively, a 12 VDC power connector is available as
accessory.
Power-over-Ethernet can be connected at the same time as a 12 VDC power supply. If auxiliary
power (12 VDC) and PoE is applied simultaneously, the camera selects PoE and shuts off the
auxiliary input.

Uninterruptible Power Supply
An uninterruptible power supply allows electronic devices to keep running for a short period
of time when the primary power source is lost. In case of an electrical power outage, the
video-based fire detection cameras will be supplied by the uninterruptible power supply.

Algorithm
The intelligent smoke and flame algorithm analyzes video frames by means of characteristic
and predefined patterns and variables. The fast detection algorithm is based on a real-time
image processing on the camera firmware.
There are factors that can influence this kind of visual fire detection. It is important to avoid
obstructions in the field of view. Sometimes obstructions cannot be prevented, e.g. building
construction factors or huge machine parts. In this case it is necessary to analyze whether
there is any need for further video-based fire detection cameras.
