NVRs & Video Recorders

Professional Network Video Recorders for 24/7 Surveillance

NVRs store, manage, and play back IP camera footage for round-the-clock surveillance recording, remote monitoring, and forensic review. The lineup from Hikvision, Ubiquiti, and InVid spans 8-channel compact units to 16+ channel rack-mount systems with built-in PoE ports, deep-learning analytics, and multi-drive bays for extended retention, all part of the security and surveillance catalog.

NVRs for Every Environment

• Small retail and offices — 8-channel NVRs with built-in PoE ports powering and recording up to 8 cameras from a single compact unit
• Warehouses and commercial properties — 16-channel recorders with dual SATA bays for extended footage retention across large facilities
• Multi-building campuses — rack-mount NVRs with hot-swappable drive bays providing weeks or months of continuous recording for organizations with dozens of cameras
• Quick-deploy installations — NVR and camera kits bundling matched hardware for turnkey surveillance without sourcing individual components
• UniFi ecosystem integrations — Ubiquiti ENVR and CloudKey+ units that unify surveillance recording with network management in a single dashboard

Choosing the Right NVR

Four factors drive NVR selection: channel count, storage capacity, PoE port availability, and analytics. Channel count determines how many cameras the NVR records simultaneously. An 8-channel unit suits small retail or residential sites, while 16-channel recorders accommodate larger commercial properties. Plan for 20 to 30 percent headroom above your current camera count for future expansion. Hikvision AcuSense NVRs include deep-learning analytics for human and vehicle detection filtering. Ubiquiti's ENVR integrates with UniFi Protect cameras and the broader UniFi platform. InVid kits package matched NVRs with compatible cameras for simplified procurement.

Storage Capacity and Retention

Storage requirements depend on camera count, resolution, frame rate, codec, and retention period. A single 4K camera recording continuously at 15fps with H.265 compression generates roughly 1TB every 14 to 20 days. A 16-camera system at that rate consumes 12TB or more per month. Determine your retention window (most commercial installations target 30 to 90 days) and select an NVR with enough drive bays to hold the required capacity. Multi-bay NVRs accept drives up to 18TB each for maximum retention.
