School Doorway Security

Scalable Security

With the availability of so many access control options, education facilities can address the specific level of protection needed for each opening. Whether combining multiple credentials, leveraging existing network infrastructure, integrating discrete components, or adding decision making capability, modern technology allows a much broader set of products. This allows for the selection of the right product to provide the right level of security within a given budget. In other words, more security for your dollar.


The most basic level of protection is a typical mechanical cylinder with a legacy key system. This can be enhanced with:

  • A patented key system, which protects against unauthorized duplication of that key
  • Geographic exclusivity, which further restricts how that key can be duplicated
  • Small format interchangeable core - a type of cylinder can be quickly removed to simplify re-keying



Keypad locks can be re-keyed electronically. If there are concerns about who has access to a building, codes can be quickly changed at any time. This provides a basic and convenient form of security. Options include:

  • Digital touchscreen lock that combines a robust cylindrical lockset with a digital touchscreen
  • Narrow stile keypads that are compatible with narrow stile aluminum, steel or wood doors



Offline locks add another element of security by incorporating audit trail features into the locking device. This feature enables an end-user to interrogate the lock and determine who opened a door and at what time - a useful tool for inventory control in areas such as maintenance/housekeeping closets or pharmacy storage rooms. Locking options include:

  • eCylinders - unlike traditional offline locks, all the smarts are located in the cylinder, making retrofitting into existing hardware quick and easy
  • Hybrid locks - features a key with two credentials: a traditional mechanical key and and RFID transponder inside the head of the key



Wireless locks record audit trail histories and use a standard WiFi connection to interact with a centralized access control system. Unlike an offline lock, a wireless lock can periodically transmit this data back to the control system and receive programming instructions as well. Features to look for in a wireless lock include:

  • Connectivity using a standard, off-the-shelf WiFi system - no need for an expensive, proprietary system
  • Compatibility with existing software and panel-based access control system
  • Real-time transactions back to the host software solution



Online locks connect directly into a building's centralized control system, giving end-users the ability to monitor and issue commands in real time.  A cost effective manner to implement online access control is to select hardware devices that are compatible with existing building control systems and do not require proprietary software. Available online access control technologies include:

  • Power-over-Ethernet - utilizes existing CAT-5 or CAT-6 network infrastructure, with intelligence built into the lock for local decision making
  • Integrated Wiegand - features open architecture platform to work with leading access control software


Hi-O Technology

Each Hi-O (Highly Intelligent Opening) device has a built-in processor that gives each doorway component intelligence as well as the ability to communicate with each other over a CANBus network. When a Hi-O device is connected, it is instantly recognized by the building control system, similar to when a USB device is connected to a computer. The benefits of Hi-O include:

  • Self-diagnostic abilities - components identify maintenance issues (similar to a check engine light on a car)
  • Standardized installation - every device has the same number of wires
  • Synchronized performance - every device understands its function and the order in which it operates
