More about Sentry Custom Security

  1. Sentry produces their own product in North America! 
  2. Sentry has had very few backorder issues
  3. Sentry provides excellent customer service
  4. Sentry costs are the lowest in the industry
  5. Sentry products are all EM-, RF-, and RFID-compatible with your existing gates


Our staff loves the wand! It's light weight, easy to use and since it's cordless, it is very adaptable. lt saves a lot of time since you don't have to pick up every book individually; you can scan the whole stack or shelf of books at one time. We also appreciate that you don't need to remove CDs and DVDs from their envelopes in order to sensitize & de­sensitize them.

- Barb Kondrick, Adult Services Librarian, Columbia Heights Public Library

Our library just had a Sentry upgrade of our 3M 3500 library security systems with the WAM/MM-RT controller. We are especially pleased with the reporting feature that allows our staff to generate reports of gate count activity. Also, Sentry's ability to access the controllers remotely should provide improved efficiency with system maintenance and reduce maintenance costs.

- James Piccininni, Dean of Library, University of St. Thomas

For a limited time, receive a free pack of EM labels with every bookwand ordered, or with every updated system. Sentry has parts to service and upgrade 3M 3500 & 3900 systems.
