Sentry Card Access Control Systems


Need help with motion sensor action units?

Sentry's motion detection units use infra-red to detect movement, then perform a defined action, such as locking, unlocking, or sounding an alarm.
These systems are very important for high-security situations - if you need help ensuring you've found the right thing, speak to Darrel, our technical expert - he can assist you!
