Fire alert systems
These types of systems are extremely necessary (combined with theft/specialized alarms) when one’s immobile assets are left unsupervised for long periods of time (vacation houses, warehouses) or when high fire risk equipment is being used.
It is better to prevent than to treat.
A fire alarm doesn’t sleep, it works 24/7, it doesn’t demand paid vacations or promotions, it can detect smoke before any human and it can see fire even without a flame ( temperature variations in the area), it doesn’t think twice about calling in the fire (it just does it), reaction times are much shorter than those of guards, it surveys the entire area simultaneously, it can announce us of any fire ( cell phone, PC)
The costs for such a system are far less pricey than those caused by a real problem.
