An intruder sensor housing for an intruder sensor comprising an integrally formed front cover and a lens. Advantageously, the lens of such a unitary structure relative to a separately formed conventional front cover and Fresnel lens can be made thinner for a given impact resistance requirement. Therefore, the attenuation of any signals passing through the lens is significantly reduced. At least one web is used to divide the housing into 2 chambers (210 and 212) separating the sensor (208) and electrical connections (214). |
