The Halo SiteGuard GSM wireless security system has 4 sensor boxes which can be installed around your premises or home. It will alert you or a monitoring company by text message if you have an intruder. A key feature of the security system is that it is battery powered (1 year battery life guaranteed) and as a result can be easily installed and moved as required. It has a build-in 7 day timer that allows it to switch off during working hours and on again at evenings and weekends.
