Guardus G3's basic idea for guard tour control is to affix the iButton at the various sites the patrol officer should check. The patrol officer then touches each iButton with Guardus G3; in doing so Guardus G3 registers the identification of the iButton which has been read, and also the date and time of the reading. Later the information stored may be downloaded into a computer, where you can generate comprehensive reports.

Guardus G3 represents a great leap from what had recently been available in the market in electronic guard tour control, being that all equipment would simply store the data and would do all processing in a computer, running a heavyload software. Guardus G3 has its own portable database. All data processing takes place inside the wand itself, therefore the software is very lightweight, due to the fact that the data processing takes place in the various wands in use.
