A wireless motion sensor alarm using acoustic sensor technology. It can distinguish between the noise of an animal and the noise from a chainsaw by analysing the sound’s intensity and duration. When a suspicious activity is detected, the alarm at the guard station will go off, prompting the guards to take action.
