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.
