Key reasons to choose Dahua include:

• High-definition and 4K camera options
  
  

• Night vision with infrared and full-color technology
  
  

• AI features like motion detection and facial recognition
  
  

• Weatherproof and vandal-resistant designs
  
  

• Seamless integration with DVRs, NVRs, and mobile monitoring apps
  
  

Step 1: Identify Your Surveillance Goals

Before choosing a camera, ask yourself:

• Are you monitoring indoor or outdoor areas?
  
  

• How many cameras do you need?
  
  

• Do you need video only, or video with audio?
  
  

• Is night-time monitoring a priority?
  
  

Your answers will help determine which camera model, resolution, and features are best for you.

Step 2: Choose the Right Camera Type

Bullet Cameras

• Long and narrow design, ideal for outdoor use
  
  

• Better for covering hallways, fences, gates, or parking lots
  
  

• Weatherproof and highly visible (acts as a deterrent)
  
  

Dome Cameras

• Compact and discreet, suitable for indoor use
  
  

• Wide-angle view makes them great for shops and offices
  
  

• Often vandal-resistant and tamper-proof
  
  

PTZ (Pan-Tilt-Zoom) Cameras

• Used in large areas that need flexible, remote-controlled viewing
  
  

• Ideal for commercial complexes, malls, and institutions
  
  

Step 3: Pick the Right Resolution

• 2MP (1080p): Great for general monitoring at homes or small offices
  
  

• 4MP–5MP: Offers higher clarity for identifying faces, plates, or fine details
  
  

• 4K (8MP): Best for large areas or high-security zones needing ultra-clear footage
  
  

The higher the resolution, the more details you’ll capture—but it also requires more storage and bandwidth.

Step 4: Consider Night Vision Requirements

Dahua offers several night vision options:

• IR Night Vision: Standard black-and-white night footage using infrared
  
  

• Full-Color Night Vision: Uses LED light to capture color footage even in darkness
  
  

• Smart Dual-Light: Switches between IR and color based on movement or lighting
  
  

Choose based on how critical clear nighttime footage is for your location.

Step 5: Look for Smart Features

Modern Dahua CCTV Cameras come with advanced features like:

• Motion detection with push alerts
  
  

• Audio recording (on select models)
  
  

• Face detection and AI-based analytics
  
  

• Remote access via Dahua DMSS mobile app
  
  

These features enhance monitoring and give you more control over your security system.

Step 6: Verify Installation Environment

• Indoor areas: Use dome cameras with wide-angle lenses
  
  

• Outdoor areas: Go for bullet or turret cameras with IP66/IP67 weatherproof ratings
  
  

• Low-light zones: Choose models with high IR range or color night vision
  
  

Always ensure compatibility with your existing DVR or NVR.
