HID Mercury LP1502 Intelligent Controller (2 Readers, 8 Inputs, 4 Outputs)

The new Authentic Mercury LP Series Intelligent Controllers are Mercury Security’s next generation advanced access control platform that runs on embedded Linux. The enhanced platform offers an improved processor and increased memory, plus feature an embedded crypto memory chip that provides a secured layer of encryption to onboard sensitive data. Built on the Authentic Mercury open platform, LP Series controllers provide the necessary flexibility for OEMs, channel partners and end customers to choose the controller configuration that best fits their needs.

The multi-port LP1502 is a dual card reader panel for controlling two connected doors and managing up to 64 doors/openings. Built on the Authentic Mercury platform, the intelligent controller uses on-board Ethernet port to connect to cloud or server based access control hosts. The intelligent controller performs access control, alarm management and scheduled operations -- all in single package.

With native connectivity, the high-performance LP1502 functions independently of the host for performing numerous access control applications and supports OSDP, OSDP Secure Channel, keypads, biometric readers, Wiegand, clock and data, magnetic stripe, F/2F and supervised F/2F reader technologies. System configuration and setup are provided through Mercury OEM partner software applications.

For partners seeking a comprehensive and open access control platform, and a reliable hardware platform running in a secure environment, the LP1502 is the clear solution. It delivers a complete security and access control solution as well as innovative application extensions, interoperability and data security.

  • Open Architecture: High performance, reliable platform enables use of hardware with Mercury OEM partners’ software solutions
  • Enhanced Security: Embedded crypto memory chip and data at rest encryption provides secured layer of protection of sensitive data
  • OSDP Protocol: Secure channel communications for reader connectivity
  • Versatile Interoperability: Same reliable interface and identical footprint as the EP controllers, enabling seamless upgrades for existing deployments
