As public transportation is becoming more popular in North America, following successful models used in foreign transportation systems can help guide our decisions and processes concerning public safety initiatives.
Adding surveillance to improve the safety of public transportation is one such example. A European bus company was looking for an industrial Power over Ethernet (PoE) switch to connect critical components of its mobile security system.
Installations on the bus included six security cameras, a network video recorder (NVR) and a Wi-Fi router, that all required communication and power. Devices used in transportation surveillance systems such as on buses or trains have a unique set of requirements and specifications that are crucial to their operability and efficiency. Devices must be compact and rugged to maximize available space, reduce crowding and survive extreme temperature conditions and harsh environments.
Comtrol’s RocketLinx ES7110-VB (voltage boost) switch is used in this security configuration to ensure quality system performance and to meet the system specifications. As cameras send data and video to the NVR, it is transferred wirelessly from the bus to a remote monitoring room via the Wi-Fi router. The RocketLinx ES7110-VB has eight 10/100BASE-TX PoE injector ports for directly powering remote equipment and reducing wiring and installation costs, and two Gigabit uplink ports for megapixel video transmission and high-quality streaming data and video. Additionally, the switch provides a 12/24VDC power input boost to 48VDC, eliminating the need for a separate power supply or voltage converter to conserve space and cost.
Featuring a DIN rail mount and measuring less than two inches in width, the ES7110-VB works well with limited space and other equipment placement in a surveillance system. Dual redundant independent power inputs for potential power loss enables a backup power supply to compensate for loss of main power and maintain camera operation. The rugged IP30 enclosure protects the switch from vibration and shock, while the -25° to +60°C operating temperature allows for installation in a variety of environments.
Comtrol’s RocketLinx Power over Ethernet switches are engineered for industrial applications such as IP video surveillance or wireless broadband, where the power source is not conveniently located. With rugged, drip-proof housings, redundant power inputs and performance command-line interfaces, these PoE switches provide reliable networking solutions.
With both managed and unmanaged models available, the RocketLinx ES series of switches provide cost-effective networking solutions delivering the industry’s best rugged Ethernet switch technologies.
