The outdoor devices LANCOM OAP-3G and LANCOM OAP-321-3Gare highly suitable for installing temporary networks, because their 3G connectivity provides an Internet connection at any site even without a cabled connection. If there is no power outlet in the area, a mobile power supplysuch as a battery pack can be connected via the device's universal power adapter.
Being able
to
to monitor the charge status of the batteryis a major help in ensuring that the OAP functions reliably and does not unexpectedly fail. The administrator can easily monitor the power supply remotely with the "Digital Voltmeter" in LANmonitor. Administrators using Syslog additionally receive alerts about low battery levels.
This document describes how you
can
can monitor a mobile power supply with LANmonitor and configure Syslog alerts.
In order for the remote access via LANmonitorto be conducted via a secured connection, we recommend that you use a VPN connection to the LANCOM OAP-3G or OAP-321-3G. You can find out how to set up a VPN connection via UMTS/3Gin
A company would like to monitor their outdoor premises by video camera. This is to be implemented with a LANCOM OAP-3G router in combination with an Ethernet-enabled video camera.
Since
the
the outdoor premises have no power sockets and because thevideo surveillance is to be flexible, a mobile power supply (e.g. a 12 V car battery) is to be used as the power source.
Thecharge state of the car battery is to be monitored from the company building by means of LANmonitor. As soon as the charge reaches the lower limit of 10 volts, a Syslog alert is to be issued.
