Monitor every luminous point in your city, highways or roads

Rererence: SKYLIGHT_US

SKY LIGHT™ is a simple, reliable and low cost system used to monitor, at night, single and multiple city streets and highways lights.
Each lamp post is fitted with a "marker" which continuously monitors the light source and the condenser for correct operation.

At the lighting power sub-station, a Central Processing Unit is connected to the power network and monitors and checks information coming from each marker.
One central processing unit can monitor a feeder with up to 30 lighting points per phase.
An optional GSM, Modem or Radio interface can call preprogrammed telephone numbers to send warning SMS's.

The communication technique, between the markers and the CPU using the energy network like medium,
is unique in the world and is the subject of a patent.
