D-Link DWM-311-TP 4G LTE Industrial M2M PoE Modem
PRODUCT DESCRIPTION
D-Link DWM-311-TP 4G LTE Industrial M2M PoE Modem (DWM-311-TP) - 3 Years Local Warranty
4G Connectivity and Power on One Cable
The D-Link DWM-311-TP is a 4G LTE Cat.4 M2M modem whose single Fast Ethernet LAN port also supplies IEEE 802.3af/at PoE. One cable delivers both data and power to an IP camera, access point or sensor — no separate power run at the device.
Smart PoE Control
PoE power control, automatic ON/OFF by network checking and scheduled ON/OFF let you remotely reboot a hung powered device or save energy out of hours.
Harsh-Environment Design
An industrial-grade metal casing, -30 to 70 °C operating range and included DIN-rail kit suit traffic cabinets, small shops, surveillance poles and autonomous mobile robots.
VPN and Cloud Management
An OpenVPN client and IPS firewall protect traffic; Web UI, SSH, SMS event management and D-Link D-ECS2 give remote control of deployed units.
