Contact Closure Sensor - OneVue Sense

Using paired magnetic strips, the OneVue Sense Contact Closure Sensor measures and records the opening and closing of doors, cabinets, windows, and refrigeration units.

When paired with OneVue software, these measurements can be logged and graphed from any browser. The sensor can also sound a local alarm, or send one through text, phone, or email.

With both WiFi and powered ethernet (PoE) networking options, these sensors can be deployed to remote and low-traffic areas to increase awareness of access and security.

A Unique Tool for Monitoring Access

When the expense and installation of a full alarm system is not warranted, but you still need to know when a door or cabinet is open, or want to monitor how often it’s accessed:

  • Blood bank or tissue bank doors
  • Server rooms
  • Cryogenic storage
  • Vaccine storage
  • Breastmilk storage
  • Low-traffic areas

Pair Sense Contact Closure Sensors with OneVue software alert features to tell you when an area or storage unit is being accessed, or you can use the logging functionality to measure the frequency of that access.
