Dahua CCTV System Builder
Take the guesswork out of home and business security with the Dahua CCTV System Builder. Whether you need a simple 2-camera home setup or a comprehensive 16-camera commercial network, our interactive tool allows you to hand-pick every component to ensure your system meets your exact requirements.
How It Works
- Step 1: Choose Your NVR: Select the "brain" of your system based on how many cameras you need.
- Step 2: Select Your Cameras: Combine best-selling adjustable turret cameras with TiOC models to customise coverage across your property.
- Step 3: Pick Your Accessories: Add cables, wall-mount brackets, and junction boxes to complete a professional-grade installation. Wall-mount brackets are used to extend and angle the camera away from the wall for better positioning, while junction boxes provide a clean, weather-protected space to house cable connections. Additional brackets are not required for eave mounting, as they are already included.
- Step 4: Add Storage: Select 2TB–12TB of surveillance-grade storage for weeks of retention. Based on 15fps, H.265, and 14-day recording settings.
- Step 5: Add a UPS: Protect your system with a UPS to keep your NVR and cameras running during outages and prevent damage from shutdowns or surges.
Why Build a Custom Dahua System?
- Tailored to Your Space: Don't settle for pre-packaged kits with cameras you don't need. Get the exact lens and features for every corner.
- WizSense AI Ready: Our builder includes the latest AI cameras featuring Human and Vehicle detection to reduce false alarms.
- Guaranteed Compatibility: Every component in our system builder is vetted by our experts to ensure seamless integration.
- Cost-Effective: Only pay for the hardware you actually use.
Guru Tip: When building your system, always account for future expansion. Selecting an 8-channel NVR even if you only start with 4 cameras allows you to add more security later without replacing your recorder!
