What is Slew to Cue?

Glossary Definition

“Slew to Cue” is a phrase that has its origins in military and defense systems but has now become a commonplace surveillance term. Slew to Cue tracking refers to the integration of a radar or other target detection device that tells an EO/IR surveillance PTZ camera where to point. The detection sensor, such as a radar, or PIDS (Perimeter Intrusion Detection System) is designed to detect the target and pinpoint its location, then transmit that information to the PTZ camera which in turn auto-tracks, identifies, and recognizes the target, day or night.

This is often the best solution as a radar can provide 360-degree coverage and can detect vehicle-sized targets up to 40km away for marine, ground or aerial targets day or night, even in bad weather conditions. The day/night PTZ surveillance cameras can then recognize and identify the targets that are detected, making slew to cue the ideal perimeter security solution for long 24/7 security and surveillance that is often applied critical infrastructure protection, and border control. Infiniti can provide both radar and cameras systems and customer builds solutions based on the application budget and mission objective.

Optional add-ons such as LRADs and long-range visible spotlights, laser dazzlers can achieve full color images at night, and serve as active deterrents as intruders feel as though they are being watched in real time due to the automated response making is the best solution for active security and surveillance.

Diagram showing how slew-to-cue works in four steps. Step 1: Radar is aware of an approaching object. Step 2: Object crosses virtual tripwire, the radar notes the location and sends coordinates to the PTZ camera. Step 3: The PTZ changes pan, tilt and zoom orientation and moves to match the coordinates given by the radar. An alert is given to the operator showing the video from the PTZ camera on the screen. Step 4: PTZ camera continues to follow the intruder using coordinates from the radar and/or analytics.
