Recommendations on characteristics for choosing the cameras:
- Minimal resolution is 2 MP.
- Minimal matrix size is 1/2.8".
- The more light sensitive will be the matrix - the better. FTC cameras are good option.
- RWDR 120 dB (camera hardware WDR), better 140 dB.
- Onvif-compliance (at least S).
Recommendations on camera settings:
- Camera bitrate has to be sufficient for required resolution, FPS an motion intensity. The camera picture has to be stable, without noise and glitches.
- Codec has to be H.264.
- Disable OSD text on camera if possible.
- Consider using only RWDR from image enhancements if WDR is required.
Factors other than camera characteristics and settings, affecting the Neural Fire and Smoke Detector performance:
- The lighting in the scene of detection should be sufficient and equal. Use visors or other protective elements to prevent glare from the sun.
- Mounting Height: Cameras should be installed at a height that provides optimal coverage of the area, but not too high to avoid glare from the sun or other light sources. The recommended height is about 2.5~3 meters. But the camera should be aimed downwards to minimize glare and provide a clear image.
- It is advisable to use cameras with a wide viewing angle (up to 90° or wider) to cover the maximum area. Focus on Critical Areas: The lens should be aimed at areas with a high fire hazard, such as electrical equipment or flammable material storage areas.
- Plan the set up considering that distance for the detection will not exceed 50 meters.
