Things to consider when installing a Verifire Camera

  1. Detection Range – It is the ideal position of the camera to detect fire or smoke considering Fire Size, Lens type and Distance.

  1. Detection Angle – It is the ideal angle to position the verifire camera with optimize fire and smoke detection.
Detection Angle

For example, the widest view angle of NC6960VD around 80-85 degree by 2.8mm setting.

Design suggestion:

1. Distance between Fire and IP Camera around 10M, Flame height around 68cm
2. Distance between Fire and IP Camera around 20M,
Flame height around 140cm
Suggestion: the effective distance for detection by 2.8mm setting is 20 M, because flame height over 150cm is higher risk.

Suggestion: the effective distance for detection by 2.8mm setting is 20 M, because flame height over 150cm is higher risk.

 

  1. False Alarm Prevention – it’s a process of adjusting some settings of either the camera or the NVR to prevent false alarm occurrences.
