Spectre RDD™ Mk IV and Mk IV + from the industry leader: Stealth Microsystems Pty Ltd. Introduction: The Spectre RDD (radar detector detector) is a sophisticated, high performance RF receiver tuned specifically to detect radar detectors. It listens for the faint microwave emissions generated by a modern radar detector and delivers an audible and visual response. The Spectre Mk IV and IV + are electronically identical but the later model is optimized for use by Commercial Vehicle Enforcement (CVE) units in regions where radar detectors are legal for passenger vehicles. Inexpensive, poorly designed radar detectors are commonly encountered in these areas. Many have poorly shielded local oscillators- the component used to generate a reference signal- and emit a powerful signal. The Spectres' extreme sensitivity enables it to detect such radar detectors at very long range, often one mile or more. This can lead to frequent, long duration alerts, often at ranges where positive target identification is impossible to establish. More expensive radar detectors typically are better engineered and have lower emissions, making them more difficult to detect. The Spectre IV + is designed to automatically reduce detection range when encountering cheap, high polluting detectors. Yet it accomplishes this with out affecting its ability to detect the higher end, low polluting models. Another attribute of the Mk IV and IV + is its enhanced ability to limit false alerts caused by the microwave signals common to urban areas. These include microwave automatic door sensors, intrusion alarms and other devices operating on the same frequencies occupied by radar detector local oscillators. Other important improvements featured on all IV and IV + models: One touch audio mute button to silence audio alerts and then restore audio volume automatically 5 seconds after the signal is last detected.
Automatic LED dimming for discrete night operation.
A high volume audible alert, easily heard over the background noise from other mobile electronics found in today's patrol vehicles.
A temperature compensated front local oscillator for improved accuracy in detecting known radar detector bands. Standard features from previous model Spectres' are carried over to the IV and IV + : Simplicity of Operation
