This compact, high-performance wireless indoor motion detector from Paradox delivers reliable human detection with excellent pet immunity, minimizing false alarms in pet-friendly homes or offices. The PMD75 (PA-3704) uses patented digital processing and dual-optic technology for superior accuracy—ideal for living rooms, hallways, or entry areas when integrated with Paradox Magellan MG or Spectra SP wireless systems.

Key Features:

• Dual-Optic Digital Detection — Two dual-opposed element sensors with patented Digital Motion Detection and Digital Dual Opposed Detection for precise, stable performance
• True Pet Immunity — Immune to animals/pets weighing up to 40kg (90lb); allows large pets or multiple smaller ones to move freely without triggering alarms
• Digital Shield Algorithm — Adjustable sensitivity (Normal/High Shield modes) for enhanced false-alarm rejection in challenging environments
• Wide Coverage — 11m × 11m (35ft × 35ft) area with 90° viewing angle; center beams up to 15m (49ft)
• Automatic Temperature Compensation — Consistent detection across temperature variations
• Single/Dual Edge Processing — Selectable modes for optimal balance between detection and interference rejection
• Supervised Wireless — 2-way communication, low-battery/tamper supervision, easy enrollment
• Energy Efficient — 3-minute power-save mode after multiple detections; long battery life (up to 3 years typical on 3 × AAA alkaline batteries)
• LED Indicator — Programmable alarm LED (enabled/disabled) for visual feedback
• Mounting Flexibility — Wall or corner mount; compatible with swivel brackets for precise aiming
