The SIP-404 is part of the Redwall-V series which is a series of long range pir motion sensors designed for use in small and mid-sized outdoor areas. The SIP-404 is a hardwired model providing a detection range of 40x4m (LxW) ideal to protect long and narrow areas. The SIP 404 features an intelligent detection system that uses data on the ambient environment, such as temperature and illuminance conditions, to automatically adjust the sensitivity. Mechanisms for easy installation enable accurate adjustment of the detection area at setup, which results in more reliable operation. The optional AVF-1 Area View Finder allows the installer to visually identify the detection area. Designed to trigger CCTV systems The REDWALL SIP series is designed to be connected to PTZ or fixed cameras and trigger the CCTV system when an intrusion occurs. The SIP-404 has two independent detection zones, far and near zones, with independent sensitivity selection, that can trigger camera pre-set and provide the best view of the scene to local security staff or remote monitoring stations. Weather and vandal-resistant REDWALL SIP PIRs are designed to be used in harsh outdoor environment, their sensitivity are adjusted automatically to the ambient temperature and illuminance, they feature an IP65 rating for the main unit. The SIP series is vandal-resistant, all SIP products are built with polycarbonate housing, featuring an accelerometer to detect whether or not the sensor position has been tampered with.
