Dahua NVR Australia – 4K Network Video Recorders

Storage requirements depend on camera resolution, frame rate, and retention period. As a general guide: 8 cameras at 1080p recording 24/7 with H.265 compression use approximately 8TB for 30 days. For 4K cameras, double that estimate. We recommend starting with a 4TB drive for small systems and scaling up. Use surveillance-rated drives (WD Purple or Seagate SkyHawk) designed for constant write operations.

Yes, Dahua NVRs support ONVIF and RTSP protocols for third-party camera compatibility. However, AI features like SMD Plus and perimeter protection require Dahua cameras. For the most reliable performance and full feature access, we recommend pairing Dahua NVRs exclusively with Dahua cameras.

H.265 (HEVC) compresses video approximately 50% more efficiently than H.264 while maintaining equivalent quality. This means you can store twice as much footage on the same hard drive or use half the network bandwidth for remote viewing. All current Dahua NVRs support H.265+ smart compression, which further reduces storage by dynamically adjusting bitrate based on scene complexity.

Download the free DMSS app from the App Store or Google Play. Connect your NVR to your router via Ethernet, enable P2P in Network settings, then scan the QR code displayed on-screen to add the device to your app. For enhanced security, we recommend disabling P2P and configuring VPN access through your router instead.

PoE (Power over Ethernet) delivers electrical power alongside data through a single network cable. This eliminates the need for separate power supplies at each camera location, simplifying installation and reducing points of failure. PoE NVRs include built-in switches that power cameras directly. For larger installations or cameras located far from the NVR, you can add external PoE switches.

Yes. Recording and local viewing continue normally without internet connectivity. The NVR records footage to its internal hard drive regardless of internet status. You will temporarily lose remote mobile access during outages. Additionally, Dahua cameras with SD card slots support ANR (Automatic Network Replenishment), which records locally on the camera if the NVR connection drops, then backfills missing footage when reconnected.

Storage duration varies by configuration. Example calculation: 4 cameras × 4K resolution × 6Mbps bitrate × 24 hours = approximately 260GB per day. A 4TB drive stores roughly 15 days; an 8TB drive stores 30 days. Factors reducing storage time: higher resolution, more cameras, higher frame rates. Factors extending storage time: H.265+ compression, motion-only recording, lower frame rates at night.

WizSense is Dahua's AI technology suite that uses deep learning to detect humans and vehicles while filtering false triggers from animals, vehicles headlights, and environmental movement. If your cameras cover outdoor areas where trees move, pets roam, or headlights sweep across the scene, WizSense dramatically reduces nuisance alerts. For indoor-only installations in controlled environments, standard motion detection may suffice.

Yes. Select an NVR with more channels than your initial camera count. An 8-channel NVR allows starting with 4 cameras and adding 4 more later. For storage expansion, choose models with 2+ HDD bays. You can add a second hard drive without replacing the existing one. Some Pro series NVRs support external eSATA storage for additional capacity.

All Dahua NVRs from SMarket include a 3-year Australian manufacturer warranty. Technical support is available through Dahua Oceania. For installation assistance, we recommend engaging a licensed security installer. Firmware updates are released regularly and can be applied through the NVR interface or web GUI.
