When specifying the maximum monitoring range, the environmental parameters must be observed. Since thieves rarely come in the daytime and in sunshine, the indication of the area under worst possible parameters such as darkness and heavy snowfall / rainfall must be made. Our systems reliably detect up to 80m away, even under unfavorable conditions, covering a surveillance range of up to 170 °. This information has been verified by our insurance and confirmed by objective measurements of independent third parties.
