It uses digital signal processing to detect human infrared energy while filtering out common false alarm sources such as air vents, radio interference, and insects. The pet-immunity feature ignores animals weighing up to 60 pounds, making it a practical choice for homes with pets. Operating on 433 MHz RF technology with a low-power PCB antenna, the sensor delivers consistent detection across a wide temperature range without signal degradation from amplification or noise. Licensed security technicians and qualified installers are the primary end users.\u003c\/p\u003e\n\u003cp\u003eThe ws4904p is suited for corner or wall-mount installation in residential spaces where pet traffic would otherwise trigger false alarms. Its hybrid installation classification means it can be deployed by professional installers or by knowledgeable end users following manufacturer guidelines. The sensor adapts to changing environmental conditions by adjusting internal detection parameters automatically, maintaining reliable catch performance across varying temperature ranges. Where wireless zoning is preferred over hardwired runs, this detector integrates into compatible DSC wireless receiver systems.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003ePet immunity rated for animals up to 60 pounds, reducing nuisance alarms in occupied residences\u003c\/li\u003e\n  \u003cli\u003eDigital signal processing analyzes IR data in software, eliminating degradation from analog amplification or noise\u003c\/li\u003e\n  \u003cli\u003e433 MHz low-power RF technology extends battery life without sacrificing range or sensitivity\u003c\/li\u003e\n  \u003cli\u003ePCB antenna design provides consistent RF coverage and sensitivity across the detection zone\u003c\/li\u003e\n  \u003cli\u003eAdaptive detection parameters automatically adjust to environmental temperature changes\u003c\/li\u003e\n  \u003cli\u003eCorner and wall mount options allow flexible placement to maximize coverage area\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style wireless PIR sensor for use with compatible DSC wireless receiver systems that support 433 MHz RF devices.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed alarm technician or a qualified installer familiar with low-voltage security system wiring and local codes. Power down or disarm the security panel before enrolling or replacing wireless sensors. Mount the sensor at the manufacturer-recommended height for the coverage pattern, using corner or wall placement as the layout requires. Do not install near heat sources, HVAC vents, or windows with direct sunlight exposure, as these can affect PIR detection reliability.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConnectivity\u003c\/strong\u003e: Wireless, 433 MHz RF\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSensor Type\u003c\/strong\u003e: Passive Infrared (PIR)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePet Immunity\u003c\/strong\u003e: Up to 60 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 4.30 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 2.50 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDepth\u003c\/strong\u003e: 2.00 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMount Type\u003c\/strong\u003e: Corner Mount, Wall Mount\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInstallation Type\u003c\/strong\u003e: Hybrid (DIY and Professional)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCountry of Origin\u003c\/strong\u003e: MX\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: DSC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: ws4904p\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"DSC","offers":[{"title":"Default Title","offer_id":51524511695154,"sku":"WS4904P","price":108.87,"currency_code":"USD","in_stock":true}],"url":"https:\/\/voomisupply.com\/products\/dsc-ws4904p-wireless-pet-immune-pir-motion-sensor","provider":"Voomi Supply","version":"1.0","type":"link"}
