Description
【Advanced Digital Signal Processing for Accurate Glass Break Detection】Powered by an 8/12-bit microprocessor (8MHz), this sensor uses sophisticated digital signal processing to analyze sound frequencies. It specifically identifies the unique frequency pattern of breaking glass while filtering out ambient noises, ensuring reliable detection when it matters most.
【Exceptional False Alarm Immunity - Ignores Pets & Common Household Sounds】Engineered with 7 frequency digital filters, digital amplifier gain control, and frequency fluctuation assessment, this detector intelligently distinguishes glass break sounds from routine disturbances. It won't be triggered by pets, loud music, dropped items, or other non-threat sounds, providing peace of mind without nuisance alerts.
【Adjustable Sensitivity with Extensive Coverage Area (Up to 30ft)】Versatile protection for any room. When set to high sensitivity and properly positioned (ceiling or wall near windows), the sensor covers up to 9 meters (30 feet). For more targeted protection, low sensitivity setting covers 4.5 meters (15 feet). This flexibility allows you to optimize coverage based on your specific space and security needs.
【Easy Integration with Existing Wired Alarm Systems】Designed as a reliable component for professional security setups. This wired detector operates on 12V DC (7.5-15V range) with low 17mA current draw. It features Normally Closed alarm output (DC28V 0.15A) and a built-in tamper switch that triggers when the cover is removed, ensuring comprehensive perimeter protection.
【Professional-Grade Construction with RFI/EMI Immunity】Built to perform in challenging environments. The sensor features high immunity to radio frequency interference and electromagnetic interference, ensuring stable operation even near other electronic devices. Housed in durable ABS plastic, it operates reliably in temperatures from -20°C to 50°C and up to 95% humidity, making it suitable for diverse installation locations.

Common questions about buying open-box and refurbished.
Why buy refurbished or open-box?
Refurbished and open-box products offer the same performance as new at a fraction of the price. You're already saving $14 on this listing. They've been inspected, tested, and are ready to use — the only difference is the price tag. Buying refurbished also reduces electronic waste, extending product life cycles and keeping functional devices out of landfills.
What's the difference between open-box and refurbished?
Open-box products are customer returns that have been inspected and confirmed functional. They may show little to no use — often the item was returned simply because the buyer changed their mind. Refurbished products have been professionally repaired or restored by technicians, tested to meet or exceed manufacturer specifications, and sometimes come with a warranty. Both are a smart alternative to buying new.
Why use OpenBoxFox?
Finding refurbished deals is time-consuming — you'd have to check Amazon Warehouse, Reebelo, Dyson Outlet, and others separately for HEEPDD products. OpenBoxFox aggregates these listings in one place, so you can compare and find the best deal without the legwork. We update pricing daily so you always see current availability and real savings.
Is it safe to buy refurbished?
Yes. Products listed on OpenBoxFox come from established retailers like Amazon, Reebelo, and Dyson — not unknown third-party sellers. Each retailer has buyer protection policies, return windows, and in some cases warranties. You get the price advantage of used goods with the purchase security of a known retailer.
