Protech SDI-77-D Indoor Pyramid Dual, 100'x10'

Deliver consistent, low-false-alarm intrusion detection across commercial indoor environments with the Protech SDI-77-D Pyramid Dual PIR motion sensor. This dual-tech motion sensor combines Stereo Doppler Microwave and dual-element Passive Infrared sensing so both technologies must trigger before an alarm is generated—dramatically reducing nuisance alerts while maintaining reliable detection. With up to 100'x10' coverage, hardwired connectivity and flexible pole or wall mounting, the SDI-77-D is engineered for critical security and surveillance applications such as warehouses, retail backrooms, loading docks and equipment rooms. Microprocessor control, balanced temperature compensation and rugged RFI/EMI protection keep monitoring stable across changing indoor conditions, while on-face LED indicators simplify installation and diagnostics. Designed for integrators and facility managers who demand dependable intrusion monitoring, the Protech SDI-77-D integrates easily into wired security systems and access control networks.
