A megapixel image covers a wider area than D1 for the same level of details.
A megapixel image provides a higher level of details for the same size of image.
We are unable to illustrate the above 2 points with photos due to limitation of the website software and storage. We can email you some photos for illustration if you ask

IP Video Surveillance provides a higher level of fitness for purposes, lower cost of ownership and operating, and more user functions than an analogue or DVR based system.
1. Clearer captured images
- Some IP cameras produce images in Megapixel resolutions (1280 x 1024). These images are more than 3 times clearer than the best analogue cameras.
- IP cameras employ progressive technique to display each frame on the monitor screen whereas analogue cameras employ interlaced technique (odd lines and even lines updated alternately). The difference will be more visible for moving objects.
- IP camera images stay as digital and do not degrade over time or distance. Analogue camera images degrade each time it is converted.
2. IP camera footage can be retrieved much faster than analogue
3. IP system provides more user functions for monitoring such as coordinating all camera live displays on a map and patrolling several sites on one screen
4. IP is the modern approach for implementing video surveillance system. Being a modern approach, it provides the benefit of future proofing to customers. That is, installed systems will get technical support and enjoy ease of upgrading and maintenacne. This situation implies that analogue equipment for video surveillance is on the way out. We will find that no more research and development effort will be spent on analogue equipment. That is, any improvements in capabilities, flexibility and scalability will happen on IP equipment only.
5. Analogue cameras are linked to the monitoring system by point-to-point cables. IP cameras do not need point-to-point cabling, and can use any standard Ethernet cable network if one exists. This is a big cost saving as well as more organized use of space for cabling.
6. DVR systems are proprietary. Once we have installed a specific brand of DVR, we wil have to use its components for expansion or maintenance. IP NVR systems are based on open PC standards. An example of benefits is the storage size and lower pricing. Storage can be tens of Terabyte, something DVR cannot do.
7. Most DVR's are designed for a max of 16 cameras. Customer will need a second DVR for installing the 17th camera. IP is scalable.

Compucon launched an iSPY workstation some 5 years ago and the product was not considered successful in terms of market acceptance. This is because the iSPY workstation was not a complete video surveillance solution and we did not provide information (assistance) on other parts of the video surveillance system such as camera and video transmission.
Five years later, we have found that IP technologies are ready for an end to end implementation of video surveillance and we are able to help with the design and implementation of a complete solution. This seminar is intended as a review of the evolution of IP video surveillance. The scope is on the infrastructure (hardware and protocols) and we will cover video management software in a future session. This session points at a blue ocean for our channel members.
