This Tilt-Sensor Switch from Quantum Instruments is a sensor to be used with the TriggerSmart camera triggering system. Along with the sound, light, and infra-red sensors included in the TriggerSmart Kit, this is a fourth, separately purchased, optional sensor that detects tilting and triggers your camera to shoot when a tilt of at least 5º is detected. By using the TriggerSmart Controller the sensitivity of the Tilt-Sensor Switch can be adjusted. The Tilt-Sensor Switch is used primarily when photographing wildlife with a tilt platform but can be used for a variety of purposes and in conjunction with the Infra-Red or other sensors.
