Unlike standard desktop drives, this unit is built to handle the high write loads generated by multi-channel video surveillance systems operating around the clock. It is designed for installation in digital video recorders, network video recorders, and standalone surveillance appliances where sustained sequential write performance and long-term reliability are the primary requirements. Security integrators, IT technicians, and professional AV installers are the typical end users for this class of drive.\u003c\/p\u003e\u003cp\u003eThis drive is suited for residential and commercial surveillance deployments where storage reliability under constant operation is critical. It fits single-drive DVR and NVR enclosures as well as small multi-bay surveillance arrays. Systems recording from multiple IP cameras or analog channels simultaneously benefit from a drive rated for this type of sustained workload. It is not intended as a general-purpose desktop or NAS drive, and should be installed only in surveillance-optimized enclosures or recorders.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e4TB storage capacity optimized for continuous surveillance recording workloads\u003c\/li\u003e\n\u003cli\u003eDesigned for always-on DVR and NVR environments with high sustained write duty cycles\u003c\/li\u003e\n\u003cli\u003eSurveillance-class firmware tuned to reduce frame loss during multi-stream recording\u003c\/li\u003e\n\u003cli\u003eStandard 3.5-inch hard drive form factor for broad enclosure compatibility\u003c\/li\u003e\n\u003cli\u003eSold as a single unit (each)\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or upgrade drive for surveillance recorders and NVR or DVR systems requiring a 3.5-inch SATA hard disk drive with surveillance-optimized firmware.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified technician familiar with data storage hardware and the specific recorder or enclosure manufacturer guidelines. Power down and disconnect the recording device fully before removing or installing any storage drive. Handle the drive by its edges and avoid contact with the circuit board to prevent electrostatic discharge damage. Follow the enclosure manufacturer mounting instructions and ensure all SATA data and power connections are fully seated before powering the system back on.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCapacity\u003c\/strong\u003e: 4TB\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrive Class\u003c\/strong\u003e: Surveillance HDD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUnit of Measure\u003c\/strong\u003e: Each\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eQuantity Per Unit\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: WESTERN DIGITAL\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: WD43PURZ\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"WESTERN DIGITAL","offers":[{"title":"Default Title","offer_id":51561815474482,"sku":"WD43PURZ","price":455.88,"currency_code":"USD","in_stock":true}],"url":"https:\/\/voomisupply.com\/products\/western-digital-wd43purz-4tb-surveillance-hard-drive","provider":"Voomi Supply","version":"1.0","type":"link"}
