LPN-SEC - LSL Security Processing Node v4.0

LSL has designed and developed a hardened Linux based embedded industrial class solution utilizing a robust distributed paradigm.   The system has many different applications. 

One of the first to see commercial success is the LPN-SEC security and tracking node.  Combined with LSL Enterprise software this system provides a complete multi-format access control solution for tracking people, assets, vehicles, and securing buildings with integrated billing/charge back capability for parking applications.

LSL provides a complete stack of software, hardware, and documentation for end to end implementation of a complete system.

LSL LPN-SEC Security Tracking Node

The LSL LPN-SEC is a hardware and software combination that provides a complete solution for access control, asset tracking, electronic door authorization, auditing, and logging.  It can be configured to utilize active RFID tags, passive RFID tags, magnetic card readers, HID ProxCards, numeric keypads and many other access control and asset tracking technologies.

This system allows the tracking, auditing, control, and immediate real-time cancellation of digital key cards.  Every RFID tag, swipe card, or ProxCard access is checked against the core security database.  If the card holder is authorized to access the area, the door mechanism is fired and opened.  A log entry for successful entry is made.  If access is denied the door is not opened and a security log is made.  This can optionally be used to notify and dispatch a security detail. 

LSL LPN-SEC can optionally support a VGA LCD panel for local key code entry or other touch screen applications.

The “LSL LPN-SEC” appliance is designed and built with off the shelf industrial grade single board computer components and the LSL Custom Linux OS.  These systems are already hardened, have extended temperature certifications, and are extremely reliable with no moving parts.

This provides stable, well supported hardware on a stable well supported Linux OS platform.  These embedded industrial computers are based on Intel Pentium III processors and have all the capabilities of a standard server appliance on a 4.5”x6.5” PCB.

The core design of the database, communication protocol, and LSL Enterprise API are completely modular.  This allows for the seamless integration of additional data types, multiple manufacturers, multiple reader or data acquisition systems to be integrated into a coherent API and protocol.  The “LSL LPN-SEC” appliance in this design paradigm becomes a distributed data acquisition node with local intelligence, processing,  decision making, data buffering and local control capability.

The product also incorporates extreme ease of use, seamless remote upgrades, and future growth.

LSL LPN-SEC Hardware Capabilities:

  • Pentium III or better class processing power.
  • 1GB DDR RAM
  • 2GB-32GB Flash Drive
  • Open COTS design allows support for any manufacturers readers, cards, device types. Simply changing the PC104 cards or USB add on's allows support for any communication or control protocol or interface.
  • Local control for each portal.  Does not rely on network for decision making or control of portals.  Highly redundant, fast and reliable control design.
  • Industrial class LPN-SEC extensible through PC104/PC104 Plus, or USB.
  • Standard class LPN-SEC extensible through PCI, PCIe, or USB.
  • Hardware watchdog timer
  • Keep alive notification to LSL Enterprise Server with Alarms.
  • Local SQL database for hardware config per channel, data type per channel, tag lookups, and local decision making and control.
  • Digital IO with relay and Opto22 capabilities, 12V 2A max std.
  • RS-232/RS-485/RS-422 on board.
  • High level API to communicate with LSL Enterprise Server and program “Tag Actions”
  • Analog to Digital, Digital to Analog boards available.
  • Distributed design allows for a single LSL LPN-SEC to serve an entire building or floor of swipe card readers.
  • Supports POE or local 12v power supply ( Control models require local power ).
  • Physical size similar to a wireless access point unit.  Depending on option boards may be slightly thicker.
  • TFT display capability, with touch screen for code entry applications.

LPN-SEC Software Specifications Version 4.0:

  • Firmware support for Advanced Paired tagging control algorithms
  • Open design allows support for any manufacturers readers, cards, device types.
  • LPN-SEC appliance capable of interfacing with Biometric ( fingerprint, iris, facial recognition ), active RFID, passive RFID, MagCard swipe, HID ProxCard, numeric keypad devices reader.
  • Track Location/Campus, Building, Room, Door, and User for each access attempt.
  • Highly resilient distributed design allows LSL LPN-SEC to function even with LES down or network non-functional.  Buffers data and allows use of LSL LPN-SEC’s to open doors and track access without central LES server being available.  When LES comes back online the LSL LPN-SEC uploads all processed buffered data.
  • LSL Enterprise Console provides a graphical user interface to all aspects of the system setup.  Includes editors for Location/Campus, Building, Room,  and User, Groups, Pairs, and authentication tables.  Setup and programming of the LSL LPN-SEC hardware units.  AES encryted secure connection to the LSL LPN-SEC hardware units.
  • LSL Enterprise Server database design specifically to support high performance, secure, multiple hardware devices, from multiple manufacturers, covering many different data types.  IE Swipe cards,  RFID tags, ProxCard, temperature, linear distance, quadrature, force, torque, etc.
  • LSL Linux OS settings configurable through LSL Server Manager
  • LSL ACS parameters, users, tags, etc. configurable through LSL Enterprise Server/Console.
  • Utilizes strong AES encryption on all network links/communications
  • Custom Linux OS distribution for LPN-SEC.
  • DHCP IP address assignment. Manual address assignment available through LSL Server Manager.
  • System software design is modular to integrate future communication capabilities such as force, torque, digital input, digital output, etc.
  • Remotely upgradeable firmware from the LSL Server Manager
  • Phase 2 Protocol LSL Enterprise API for communication with LPN-SEC through LSL Server Manager
    • Secure AES encrypted communication
    • Remote IP parameter configuration.
    • Time setting and retrieval.
    • Data retrieval from multiple access control reader units.
    • Local control configuration for remote setup of controls for door solenoids, auto openers, multiple door control with single reader, etc.
    • Status retrieval and updates of unit health and communications.
    • Protocol designed from inception to support multiple device types, multiple device manufacturers, and multiple data types.

Customer Responsibilities:
