The requirements for cameras

when you work with

the Fire detection and

Smoke detection modules are

given in the following table.
It is recommended to use - We recommend using color cameras.

With - When you use black and white cameras, the recognition quality
|
may Resolution should - Resolution must be at least 640x360 pixels.
- Number of frames: the detection response rate
|
of the detection module - depends on the number of frames per second
|
, , it is 1 per every (, - it is enough to detect a fire/smoke that lasts more than

Object images | - The minimum area of fire/smoke in the frame depends on the neural network used. For a standard neural network (
|
see the should - must be at least 10% of the frame area.
|
In - In some cases, when the fire is well contained,
|
it may be sufficient for a detection tool that - the width/height of the fire zone
|
is - as 1-3% of the width/height of the frame
|
.- can be sufficient for the detector

If you specify the surveillance area of interest is specified on the video image, then the above requirements are relevant for it , and not for the entire frame (see see Configuring the Fire detection and Smoke detection modules). We don't guarantee the correct operation of fire and smoke detectors when you use the video stream and frames that were masked before they got to Axxon PSIM by the IP camera or similar means and methods. |
