I am working as a supervisor in a home renovation. We were availing security service from a firm. But we came to know that many security guards working there are not qualified. We need well-trained security guards. Our company needs security people who can handle an emergency situation caused due to hazardous material. And someone who can monitor the mechanical equipment. It will great if someone helps me with the criterion that I should check before selecting the security guard. My friend suggested a industrial security system vendors that can help us. We thought of including Real Time License Plate Alert Systems. Gun Shot Detection, Wrong Way Detection, Facial Recognition & Human Congregation Detection. It will be great if someone can help with the average expenditure for this service.
