- Each image formed from two interlace fields
- Blurriness from capturing moving objects even when connected to a DVR
- Entire Image captured at one time
- Crystal Clear Images even with a high degree of motion in the scene
2. Ease of Installation
• 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
• 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
• 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
• 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
• 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
• 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
• With every conversion, image quality is lost
• Only one video stream available
- Images digitalised once
- No image degradation
- Multiple and simultaneous video streams
