ZZ Marts’ Wireless Burglar Alarm System category stocks complete perimeter and building security setups — dual-beam infrared outdoor perimeter sensors (50m, 100m, and 250m range, IP55 rated), an 8-zone PSTN telephone-line alarm control panel, a GSM wireless alarm control panel with keypad, and a high-decibel wired siren for an audible alert. These work together to cover both the boundary of a property and individual doors or rooms, with GSM models able to send alerts directly to your phone.
