Using PoE Switches to Enable
Homeland Security Surveillance Systems
Leveraging Existing Infrastructure and Flexibility With homeland security a national priority since 9/11, deploying a city-wide security surveillance system has become particularly important to safeguard citizens, critical public facilities (e.g. power substations and water/wastewater treatment plants), as well as key border crossings (e.g. airports and highway checkpoints). As a result, surveillance cameras are appearing more and more in critical public venues. Security cameras are typically installed at remote or outdoor settings where it would be inconvenient or infeasible to provide a separate power source. In response to the challenge of supporting this rapidly growing security infrastructure with flexible and affordable solutions, PoE technology delivers electrical power to security devices over the same Ethernet cable, dramatically reducing overall installation and maintenance costs. In addition to surveillance cameras, the demand for intercom systems, access systems, wireless access points, RFID tracking, VoIP phones for emergencies, and other security equipment requiring high-bandwidth networks to operate continues to expand.

Application Description
Public security systems are often built in areas with limited real estate. PoE enabled managed switches (the EDS-P510) feature four 10/100BaseT(X) PoE ports to power networked devices including IP cameras, wireless PDAs, VoIP phones for emergencies, and other IEEE 802.3af compliant security devices.
IP surveillance cameras adopted for homeland security are now compliant with PoE IEEE 802.3af standards. The EDS-P510 is used to leverage existing network infrastructure while enjoying the flexibility of future expansion.
Higher bandwidth networksare required to enable real-time monitoring and emergency response in homeland security applications. The EDS-P510 supports up to three Gigabit SFP ports. Two of which form a Gigabit fiber ring backbone, which connect many different security sub-systems for seamless communication and reliable video, voice, and data transmission as well. The third Gigabit fiber port is activated to uplink to the remote monitoring center.
Additionally, Ethernet with fiber cabling benefits public security by offering great EMI immunity, high bandwidth, long haul transmission, and cost advantages.
Network redundancy is the primary factor in ensuring continuous operation for security systems. The EDS-P510 particularly supports Gigabit Turbo Ring with faster fault recovery that helps critical security networks operate continuously and reliably.
Securitysystems are often installed in remote locations and exposed to harsh conditions. An extended temperature range of -40 to 75°C is essential to withstandingsuch extreme weather variations.
In public security systems, Active Ethernet I/O devices, such as the ioLogik E2214,can trigger streetlights. PLCs are deployed for a range of public tasks includingtraffic information systems and traffic signal controls.
VoIP phonesare a preferred solution for emergency communications between public areas and the control center.
Moxa Solutions
PoE enabled solutions:
The EDS-P510 packs four 10/100 PoE ports to power IEEE 802.3af compliant devices. Up to three Gigabit ports can be used to form a Gigabit ring backbone and uplink.
The unique design of SFP/copper combo ports allow flexible configurations for fiber and copper connections based on network architecture needs.
Faster fault recovery with Gigabit Turbo Ring technology, an extended temperature range of -40 to 75°C, dual redundant power inputs, and other rugged features bring you peace of mind when constructing a safe public security system.
The PoE injector is connected to supply power to PoE devices if current PoE ports are insufficient to deliver power in existing Ethernet networks.
Managed or unmanaged PoE switches may be chosen based on whether or not a redundant layout is required.
IP cameras (VPort 25) with vandal-proof, IP66-rated and day-and-night CCD camera lenses are specially designed for public security surveillance. The unique combination includes redundant power inputs with direct power connection (12/24 VDC and 24 VAC) and PoE (IEEE 802.3af) capability.
Full D1 video encoders (VPort 351) are ideal for digitizing CCTV surveillance systems for IP-based platforms. A -40 to 75°C operating temperature range promises long-term durability under outdoor environments.
Industrial Ethernet I/O devices (ioLogik E2214) allow flexible digital input and relay output configuration to suit your application needs.
