The reason is simple: Often, those places are just too large to place smoke detectors and fire alarms in all the required spots to cover the entire area seamlessly.
Should a fire break out at some time, chances are it might happen in one of those spots where there is no fire or smoke detector nearby.
It will take time until flames and smoke reach a detector, if at all. Time in which there can already be significant harm and damage done.
So what is the best way to increase fire safety in such places?
Digital image processing has gone a long way. Today there exist fire detection cameras such as the spotfire camera (“f-cam”) that can detect fires quickly and efficiently. As compared to smoke detectors, fire detection cameras have many advantages.
For instance, distance to a flame and smoke doesn’t play a role any longer. While a smoke detector must be in vicinity to a flame or heat, the fire detection camera can be placed at a distance where it can have an overview over a vast area. When a flame is spotted, the camera can trigger an alarm right away without any delay. Alerting about a fire at the earliest possible time means that it can greatly help to reduce damage.
Another advantage of the f-cam spotfire camera is that it can be integrated into existing CCTV systems which almost any sports venue has already. This means maximum fire safety for minimal effort.
