Seamless integration with most wireless alarm systems (compatible with 433MHz receivers). Compact wall-mount design (12.5×8.5×3.2cm) blends into homes/offices/warehouses. DIY installation with screw-free adhesive backing or pre-drilled mounting holes.
Energy-efficient operation: 3×AA batteries (not included) last 12+ months. Tamper-proof casing triggers anti-sabotage alarm when opened. Ideal for backdoors, hallways, retail displays, or storage units.
Bulk pricing available for property managers and security distributors. FCC/CE/RoHS certified.
