Physical security barriers from the start, including door locks, alarms and other measures, as a result of these barriers can only delay the invasion, but could not prevent the invasion, so the building with the security systems in order to reduce the protection of human, more vulnerable to reinforce barriers , or are unable or not suitable for the installation of barriers on the region, under the protective net cloth to detect and warn of illegal intruders.

The top floor of the existing building did not have access control or the preservation of alarm systems, building security, therefore a serious threat. In Singapore, for example, building towers on the top floor was unknown because of damage to water quality, water quality affecting the residents, and thus pose a threat to life and general market, however, if the installation of alarm systems, not only in each building to connect to wired network, power consumption time-consuming work, lines are also vulnerable to damage; In addition, the preservation of the general alarm system equipment range, relatively high cost, and easy to use Keypad password cracking, security and real-time are inadequate.

In this case, the top floor in each building install MA8-2 system and terminal equipment, such as Reed, alarm, electric door lock and LED warning lights through the TTL and MA8-2 link, the user control through the mobile phone alert state, the mobile phone number as a personal ID, MA8-2 will identify whether the authorized user to control the alert staff that there is any movement will immediately MA8-2 through the Internet via the GPRS network automatically returns the control center and at the same time in a newsletter First time to notify the relevant emergency management personnel to deal with. The system without the traditional Alarm Panel, Keypad, Alarm Receiver, and many other devices, and can be completed in a very short period of time to build, it is for the best solution for integrators.
