1.4.2 VEGA WIRELESS CAMERA GPRS CONNECTED TO AN ADSL ROUTER
In this scenario, the Vega Wireless Camera GPRS uses a faster means of transport: the ADSL line. An
ADSL Router was connected to the camera LAN port in order to monitor the real status and the alarm-
relevant images by a remote station. This process is much faster if compared to the use of a GPRS network.
As for the previously described application, the Vega Wireless Camera GPRS captures and saves the
images to an internal volatile memory: when the memory limit is reached, older images are overwritten by the
most recent ones.
A presence detector, the Sensor, is connected to one of the Vega Wireless Camera’s GPRS digital inputs.
When an alarm is detected, the images preceding and following the alarm event are saved to the camera
flash memory (non volatile memory). At this point the Vega Wireless Camera GPRS activates an Internet
connection by using the GPRS network and sends a SMS to the users who were added during the
configuration process to alert them on the intrusion.
The images saved by the camera can be accessed by a remote station via any device provided with a web
browser (e.g. Internet Explorer, Firefox, Safari, Opera): a computer, Macintosh, PDA or advanced mobile
phone connected to the Internet.
