Q: What are the key benefits of using network cameras over traditional analog cameras?

A: Network cameras offer a multitude of advantages, including superior image quality, enhanced security features, greater versatility, and a future-proof solution for your security needs.

1. End to Interlace Problems

  • Each image formed from two interlace fields
  • Blurriness from capturing moving objects even when connected to a DVR
Progressive Scan Vs Interlaced ScanDigital - Progressive Scan
  • Entire Image captured at one time
  • Crystal Clear Images even with a high degree of motion in the scene

2. Ease of Installation

Analog Camera
• Power Over Ethernet Not Available

• Remote Setup and Verification Not Possible


  • IEEE 802.3af and IEEE 802at (PoE+) Industry Standards
  • One Cable for Video Data & Power
  • No Need for Power Outlet at Camera Location
  • Remote Zoom & Focus

3. Megapixel Resolution & HDTV Capabilities

Analog Camera

• Stuck with NTSC/PAL resolution
• 0.4 Megapixel at 4CIF and 0.1 at CIF
• Limited image details




  • Different aspect ratios
  • 1 megapixel is 3x the resolution of 4CIF, 2 megapixel is 6x!
  • Exceptional image quality


 4. Intelligence at the Camera Level

Analog Camera

• No Intelligence Available




  • Intelligent Video
  • Add functionality over time
  • Automatic analysis, detection & alerts
  • Initiates recording, alarms or other action

 5. Integrated audio and PTZ control

Analog Camera• Separate Cabling for PTZ Control for Video & Audio
• Costly & Cumbersome
• Only Possible with Separate Audio Lines to the DVR


  • PTZ control over the same network that transports the video
  • Audio captured at the camera
  • Synchronised with the video
  • Can be integrated into the same video stream

6. Secure Communication

Analog Camera


• No Encryption
• No Authentication
• Anyone can tap into the video or replace the signal


  • Video encryption
  • Authentication using encrypted certificates
  • Authorisation: to verify and approve the identity of the device
  • Privacy

7. Open and Easy to Scale

Analog Camera• Dedicated Cables with Specialised Function: Coax,Fibre & Wireless
• Adding Power, I/O & Audio Further Complicates this Situation
• Not Possible to Upgrade & Add More Functionality

  • IP standard, interoperable;
    Fixed and wireless
  • System scalability
  • ONE cable for video data,
  • audio, PTZ control and power
  • A single network wire = hundreds of simultaneous full frame rate video streams


• Dedicated Cables with Specialised Function
• One Cable only for One Video Stream
• Cable Length Affects Image Quality

  • IP standard cable with multiple functionalities
  • One cable for multiple video streams
  • No reduction in image quality

    8. True Digital Solution

Analog Camera

• With every conversion, image quality is lost
Only one video stream available

  • Images digitalised once
  • No image degradation
  • Multiple and simultaneous video streams
