Many businesses are enhancing security operations by integrating physical security gateway control solutions with digital security surveillance (DSS) systems. These integrated DSS/gateway solutions provide real-time intelligence for live detection of safety and security events. They can be instrumental in automating secure entryways in buildings and parking lots that help safeguard employees and facilities, provide forensic evidence in the event of an intrusion, and optimize workforce management by tracking employees’ comings and goings. Increasingly, these solutions are also becoming part of the Internet of Things (IoT), enabling remote access to videos and data and connection to the cloud.


From an embedded computer perspective, an integrated DSS/gateway solution for a single building requires just two systems: a server and a client. Other common components include cameras, alarm panel and alarms, sensors, switch and mobile clients (Figure 1).

The server needs a rich I/O interface for connecting multiple devices such as IP cameras, security sensors, alarms, and control panels. It must be powerful enough to process and store all the incoming data, issue alerts, and respond quickly to requests for security video and data whether for actionable intelligence or evidence. The platform should also be powerful and scalable enough to handle video analytics applications. Such applications can identify suspicious actions (e.g., an intruder following a person with an entry card through a doorway) and other noteworthy events. They can then direct the corresponding video clips to storage and issue full HD video alerts to client and remote devices, such as a tablet or smart phone.


The client should be a compact box computer that delivers excellent graphics and media performance to one or two monitors. It should provide I/O and expansion capabilities for peripherals such as external hard drives. For security, a SIM card reader ensures only authorized personnel can use the client.


Lanner Electronics, an Associate member of the Intel® Internet of Things Solutions Alliance, recently put together such a solution for a customer looking for an integrated DSS/gateway system.


At the heart of the system is the Lanner LEC-2430 (Figure 2). This small form factor, fanless design makes an excellent, quiet choice for a tough integrated DSS/gateway server capable of efficiently handling video and entry control. To deliver the necessary performance, it offers a range of quad-core Intel® processors, including the 64-bit Intel® Atom™ processor E3845 and the Intel® Celeron® processors J1900 and N2930.

What’s more, the LEC-2430 is equipped with one mini-PCIe, one PCI and one PCI-E riser card, offering extremely flexible expandability. These expansion interfaces can be leveraged for adding additional I/O and communications ports, not only improving a system’s functionalities but also simplifying the complicated tasks faced by system integrators and developers. Addition features of the LEC-2430 are 1x USB 3.0, 4x USB 2.0 ports, 2x GbE,  a 2.5” SSD/HDD drive bay, SATA type II socket and up to 4GB DDR3L.


For the client, Lanner’s integrated DSS/gateway solution uses its LEC-7330 (Figure 3). This fanless and robust embedded box PC system offers a similar choice of processors – Intel Atom processor E3845 or Intel Celeron processors J1900 and N2930 – to deliver excellent graphics and media performance.

The LEC-7330 comes with not only a hot-swappable 2.5” or 3.5” bay for a SSD/HDD drive, but also support for VGA (1600x1200) and HDMI (1920x1080) at 60 frames per second to provide crisp, clean video footage, making the LEC-7330 a low-maintenance platform for setting up video-heavy industrial deployments. Other features include 1x USB 3.0, 2x USB 2.0, up to 4GB DDR3L, dual GbE ports and wireless capabilities (WiFi and 3G/GPS) via the mini-PCIe. The LEC-7330 can be secured in a number of settings via VESA and wall mounting kits.


Both box computers are designed to deliver in limited space the kind of stability and longevity required for surveillance analytics and physical security gateway control systems. Their fanless designs help ensure hardware uptime and availability, minimizing manpower and maintenance and repair costs.


The Processor

The selected Intel® Atom™ and Intel® Celeron® processors combine the requisite compute and media performance, connectivity, and security with the power budget to meet the needs of compact DSS and gateway control IoT systems. The processors use Intel’s Silvermont microarchitecture and 22nm process technology with 3-D Tri-Gate transistors to deliver significant performance improvements compared to the Intel® Atom™ processor N2000/D2000 family (Figure 4). This performance increase gives these processors the processing power to handle video analytics applications tracking everything from people moving in the wrong direction to license plate reading – applications crucial to setting up event-driven DSS solutions that relieve security staff from monotonous viewing of live video.

In terms of video performance, the selected processors include Gen 7 Intel® Graphics Technology. The included Intel® Quick Sync Video delivers hardware acceleration for video decoding for H.264, MVC, VPG8, JPEG/mJPEG, VC1/WMV9, and MPEG2 standards. Intel® HD Graphics 4000 technology provides up to five times the 3D graphics power and 80 percent higher decode performance over previous Intel Atom processor generations. These boosts enable dramatically improved DSS performance on small and large screens.


The processor family is capable of simultaneously decoding 11 camera streams of 1080p video. On clients, the processors improve user experiences with smooth HD 1080p video playback and dual-display support (HDMI 1.4a and DisplayPort 1.1).



Encryption is often a key requirement for integrated DSS/gateway solutions, particularly when employee information may be involved. Once only available in Intel® Core and Intel® Xeon® processors, the Intel® Advanced Encryption Standard New Instructions (AES-NI) included in these Intel Atom and Intel Celeron processors accelerates data encryption and decryption, helping secure video data and other information through transmission channels. Seven new instructions for cryptographic processes minimize processor loading, saving processor cycles for other actions. The result is secure customer data with less performance hit.


For additional security, the Intel Celeron processor and Intel® Atom processor E3800 product families support Secure Boot. This feature ensures that a platform boots into a known, verified state. The feature defines an interface between operating system and firmware/BIOS that when enabled and fully configured helps a computer resist attacks and infection from malware.


Intel® Atom™ or Intel® Celeron® Processors – Which Do I Want?

Aside from minor differences in processor base frequency, the primary difference between these 10 watt and under processor choices is that the Intel Atom processor E3845  offers an industrial temperature range (-40°C to 110°C). This can be a great reliability and data integrity feature when devices might be placed unheated areas such as warehouses, parking lots and garages. Otherwise, the processors are very similar in features and performance-per-watt benefits.
