Security System Builder
Build your own alarm system.
Choose an alarm panel, add the sensors your space needs, then a repeater and extras. Live prices, all added to your cart together.
Choose your alarm panel.
The panel is the brain. It sounds the siren and calls or messages you when a sensor is triggered.
Tell us about your space.
We suggest a starting set of sensors. You can change every number below.
Add sensors.
All sensors here are 433 MHz wireless, the same type sold with ACJ-400, 402, 405 and 407 kits. No wiring to the panel.
Repeater.
Boosts the wireless signal when sensors are far from the panel, behind several walls or on another floor.
Add-ons.
Fire safety and cameras to round off the setup.
Questions, answered.
Which panel should I choose?
ACJ-400 has a keypad with Wi‑Fi and GSM auto-dial. ACJ-402 works with the Smart Life app and supports up to 100 wireless zones. ACJ-405 has a 2.4-inch touch keypad and dials up to 5 numbers. ACJ-407 has a 4.3-inch colour touch screen. For warehouses, factories and large premises, ACJ-1008 adds TCP/IP plus 4G and supports up to 64 wireless sensors.
Do I need a SIM card?
For calls and SMS alerts, yes. The GSM panels need a SIM card in the panel. App alerts work over Wi‑Fi.
When do I need a repeater?
When a sensor is far from the panel or separated by several walls or floors. The REP5H-43 repeater receives sensor signals from about 100 m in open ground and forwards them to the panel.
Which sensors work with ACJ-1008?
Use the ACJ-1008 door sensor and PIR motion sensor listed in the builder. For other sensors, message us and we will confirm compatibility first.
