In-Vehicle Networking
NEXCOM has released two fanless in-vehicle PoE switches to simplify the installation of in-vehicle technology to address the growing need for onboard video surveillance and internet connectivity.
VES30-4S

VES30-4S mobile PoE switch is designed for telematics applications in harsh environments with fanless enclosure. It provides 5 Giga bit Fast Ethernet ports including 4 IEEE 802.3af compliance PoE ports to transfer large amounts of video streaming, voice and critical data across Ethernet network smoothly and quickly.
As the power source from a vehicle is unstable by nature, the mobile PoE switches support a wide voltage input range of 9VDC to 36VDC and provide smart power management with low battery voltage protection, power-on and power-off delay timer, and auto ignition power on/off functions. These unique features can secure reliable operation and prevent premature failure of both the PoE switches and vehicle.
VES30-4S is encased in a fanless dustproof enclosure and can operate under shock, vibration, and temperature extremes from -30 to 70°C. The mobile PoE switches are also small in size and support din rail mounting for ease of installation with PD devices such as IP cameras and Wi-Fi access points.
