The Redwall 404 are PIR sensors specifically designed for external CCTV detection applications. Their small size, attractive appearance and accurate detection makes them ideal for the activation of video transmission systems and the positioning of pan and tilt or dome cameras. They can also be used on manned CCTV systems to alert an operators attention to movement in a specific area. These detectors are single ended devices and do not emit or transmit signals. They are safe for use in all applications.

125' x 30' Curtain

Detection is achieved by monitoring far infrared levels between an intruder and the background in the detectors multiple fields of view. These detectors use twin dual element sensors and twin electronic processors to achieve detection while maintaining operational stability. A precision optical array combining reflective and refractive lenses provide the sensors with a precise coverage pattern that can be accurately aligned using the LRP1020 Audio Walk Tester.

The Redwall 4010, 404 and 3020 are simple to install and maintain. The detachable mounting bracket allows the sensing head to be accurately adjusted to offer precise alignment. Setting up and walk testing is made easy with an LRP 1020 Audio Walktester. This uses a sweeping sound method to show exactly the position of the detection areas. The Redwall 4010 and 3020 come complete with comprehensive installation instructions, security key to lock the sensing head in position and fixing kit for mounting.

The Redwall 4010, 404 and 3020 sensing electronics are housed within a screened metal enclosure which, being located in the sensor's cast aluminium head, are thereby doubly protected against radio interference. Comprehensive decoupling of the electronics also adds to the sensor's ability to reject sources of electro-magnetic and electro-static interference.

The Redwall 4010, 404 and 3020 are ideally suited to all external applications. Typical installations include car compounds, retail warehouses, electrical substations, storage areas and building perimeters.

When used in conjunction with an LRP 105 Interswitch these sensors can be used to simultaneously control lighting thereby reducing both energy and maintenance costs while increasing site security
