Paradox Security Systems 29
From outdoor and pet-friendly digital motion detectors to analog motion detectors, the Paradox series of motion detectors combine
advanced features and patented technologies to provide a high level of detection and false alarm prevention.
The Digigard (DG55, DG65, DG75 and DG85W), Digital Vision (525D) and Paradome DG466 line of motion detectors offer patented
digital motion detection. Developed for high-security applications, this advanced circuit design performs direct analog to digital
conversion of the PIR sensor’s signal using a powerful, high-speed microprocessor-based digital IC. Completely software-driven, true
digital motion detection converts, amplifies and processes the sensor’s low-level signal in the digital domain without any analog circuitry
(no saturation, no loss of data and no noise). This unique technology provides increased accuracy, reliability and superior false alarm
immunity.
The Digigard series includes a DG85W Outdoor Digital Dual-Optic High-Performance PIR (40kg/90lb True Pet Immunity) that combines
a special weatherproof design and the proven technology of our DG75 Digital Dual-Optic High-Performance PIR (40kg/90lb True Pet
Immunity) to provide the same reliable protection—outdoors. With its patented optics and digital processing technologies, the world-
renown Digigard DG75 is a reliable false-alarm free motion detector with unmatched pet immunity.
Our patented Auto Pulse Signal Processing transforms the signal energy to a pulse output to determine if the progression of the detected
occurrence corresponds to an alarm condition. Energy from the signals are measured and stored in memory until a minimum level is
reached. The processor then rejects signals that do not meet its required specifications for generating an alarm.
Whatever the application, there’s a Paradox motion detector that will suit your needs and surpass your expectations.
