Introduction to Dahua Home Cameras

Dahua home cameras, such as the WizSense and WizMind series, are IP-based devices known for their high-quality images, intelligent analytics, and user-friendly interfaces. These cameras support features such as motion detection, AI-based analysis (e.g. human/vehicle classification), and remote viewing via mobile apps or PCs. Key models include fixed lens cameras, pan-tilt-zoom (PTZ) cameras, and Wi-Fi enabled options to meet various home surveillance needs.

To effectively use a Dahua camera, you need to understand three key aspects:

  • Image Settings: Adjust resolution, compression, and other parameters for optimal video quality.
  • Storage: Configure local, network, or cloud storage for video recordings.
  • Remote access: Set up secure access to live feeds and recordings from anywhere.

Configuring Image Settings

Image settings determine the clarity, size, and quality of video streams. Proper configuration ensures clear images while optimizing bandwidth and storage usage. Below are the main settings that can be adjusted via the camera’s web interface or Dahua’s SmartPSS software.

Accessing the Web Interface

  • Connect the camera to your network using an Ethernet cable or Wi-Fi.
  • Find the camera’s IP address using Dahua’s ConfigTool or by checking your router’s device list.
  • Open a browser (preferably Internet Explorer for full compatibility) and enter the IP address of the camera (e.g. 192.168.1.108).
  • Log in using the default credentials (user name: admin, password: set during initialization). Change the password immediately for security reasons.

Key Image Settings

  • Resolution: Determines the clarity of the image. Common options include 1080p (2 megapixels), 4 megapixels, or 4K (8 megapixels). Higher resolutions provide more detail, but require more storage and bandwidth. For home use, 1080p or 4MP is often sufficient.
  • Compression: Dahua cameras support H.264, H.265 or MJPEG. H.265 provides better compression, reducing file size up to 50% compared to H.264, ideal for long-term storage.
  • Frame rate (FPS): Typically set between 15-30 FPS. Higher FPS (e.g. 30) captures smoother motion but increases file size. For static scenes, 15 FPS is sufficient.
  • Bitrate: Controls the data rate for video streams. Options include CBR (constant bit rate) or VBR (variable bit rate). CBR ensures consistent file sizes, while VBR adjusts quality based on scene complexity. Set to 2048-4096 kbps for 1080p.
  • Main vs. Extra Stream: The main stream is used for recording (high quality), while the extra stream is used for remote viewing (lower quality to save bandwidth). For example, set the main stream to 1080p at 15 FPS and the extra stream to 720p at 10 FPS.
  • Image adjustments: Adjust brightness, contrast, saturation, and sharpness to improve visibility. Enable Wide Dynamic Range (WDR) for high-contrast scenes (such as doorways with bright sunlight).

Motion Detection and AI Features

  • Enable motion detection to trigger recordings only when motion is detected, saving storage space.
  • Configure sensitivity and detection zones to reduce false alarms (e.g., ignore tree movement).
  • WizSense cameras offer AI-based features such as human/vehicle detection to reduce false alarms. Enable these in the Intelligent Video System (IVS) settings for smarter alerts.

Storage Options for Dahua Cameras

Dahua cameras support multiple storage methods to ensure video footage is stored securely. Choose based on your needs for accessibility, capacity and redundancy.

Local storage

  • MicroSD card: Many Dahua cameras have a microSD slot (up to 256GB). Go to the camera’s web interface, navigate to Storage > Destination > SD Card, and enable recording. Format the card first to ensure compatibility.
  • HDD via NVR: Connect the cameras to a Dahua Network Video Recorder (NVR) with an internal hard disk (up to 10TB). In the NVR interface, go to Storage > Schedule to set the recording modes (continuous, motion-based or alarm-triggered).
  • PC-based storage: Use SmartPSS software to store recordings on your PC’s hard drive. Configure under Storage > Local Storage.

Network Storage

  • NAS (Network Attached Storage): Dahua cameras support the NFS protocol for NAS storage. In the camera web interface, go to Storage > Destination > NAS, enter the IP address of the NAS server and the path of the shared folder (for example, /home/nas/recordings), and enable recording. No NAS password is required for NFS.
  • FTP Server: Configure the camera to upload snapshots or clips to an FTP server. Navigate to Storage > Destination > FTP, enter server details and schedule uploads.

Cloud Storage

  • Dahua cameras can integrate with third-party cloud services via FTP or SMTP servers. For example, CameraFTP provides cloud storage compatible with Dahua devices. Configure in Storage > Destination > FTP/SMTP.
  • Some Dahua NVRs support cloud storage subscriptions for offsite backup, which can be accessed through the DMSS application. Please check the Dahua website for supported providers.

Recording Schedule

  • Set a recording schedule in Storage > Schedule. Options include
    • Continuous: Records 24/7, ideal for critical areas, but uses more storage.
    • Motion detection: Records only when motion is detected, saving space.
    • Alarm/IVS: Records when specific events (e.g., tripwire, intrusion) are triggered.
  • Copy settings to multiple cameras to streamline configuration.

Setting Up Remote Access

Remote access allows you to monitor live feeds and review recordings from anywhere using a smartphone, tablet or PC. Dahua’s DMSS app and SmartPSS software are the main tools for this.

Requirements

  • A Dahua camera or NVR connected to a router with Internet access.
  • A smartphone with DMSS application (available for iOS/Android).
  • A PC running SmartPSS software (optional for advanced management).
  • A stable Internet connection (at least 3 Mbps upload for smooth streaming).

Configuring P2P for Remote Access

P2P (peer-to-peer) is the simplest method for remote viewing and does not require port forwarding. Follow these steps:

  • Enable P2P on the device:
    • Access the web interface of the camera or NVR.
    • Navigate to  Setup > Network > P2P.
    • Enable P2P and check that the status shows “Online”. Make a note of the QR code or serial number (SN).
  • Set up the DMSS app:
    • Download DMSS from the Google Play Store or the iOS App Store. Avoid older applications such as iDMSS or gDMSS.
    • Open DMSS, tap the “+” icon, and select “SN/Scan”.
    • Scan the P2P QR code displayed on the device or enter the SN manually.
    • Enter the device’s user name and password (for example, admin and your custom password).
    • Save the settings to add the device. You can now remotely view live feeds and recordings.
  • Enable Notifications:
    • In DMSS, go to Device Details > Notifications.
    • Enable notifications for motion detection, IVS events (such as tripwire), or AI analytics.
    • Select channels to receive notifications for specific cameras.

Alternative: Port forwarding

For advanced users, port forwarding allows direct access using the camera’s IP address. This requires

  • A static IP or DDNS (Dynamic Domain Name System) for your network.
  • Router configuration to forward ports (for example, 80 for HTTP, 37777 for TCP).
  • Security measures such as VPN or HTTPS to protect against unauthorized access.

Note: P2P is safer and easier for most home users because port forwarding exposes devices to the Internet.

Viewing on PC

  • Install SmartPSS from Dahua website.
  • Add the camera or NVR by its IP address or P2P SN.
  • Configure remote access by enabling DDNS or port forwarding in your router.
  • Access live feeds, playback recordings, and manage settings from the SmartPSS interface.

Security Best Practices

  • Change default passwords to strong, unique passwords.
  • Enable two-factor authentication (2FA) in DMSS if available.
  • Update camera and NVR firmware regularly to patch vulnerabilities.
  • Avoid exposing devices directly to the Internet without VPN or secure tunneling.
