e-alert is a single zone security system, that provides 24x7 round-the-clock security and can be used in smaller homes or shops. It can be interfaced with both wired and wireless sensors. It generates high volume siren and can be controlled through remote. It also has automatic power back-up with huge back-up time and is primarily targeted at rural areas where there is frequent power-cuts. It consumes very low power and has very low maintenance. A panic or emergency button is also provided in remote, which works whether the system is enabled or disabled.
