|Compucon Seminar on IPVS Systems 2011|
Continuing Professional Development plays an important role in assisting Compucon channel peers to remain current and develop new competencies in information technology practices. Venue is Compucon House Albany. Date is 21 September 2011 Wed.
Video Surveillance Cameras
IP cameras have 26 attributes and not all cameras have all or the best of them. Whilst we want to install cameras that have high clarity under all sorts of scenarios, we will have to be prepared to pay a premium price to meet our needs. In practice, we do not need to pay the full price. We should pay for what we need and therefore we should learn about the range of IP camera features to prescribe our wish list. Specifications are not as straightforward as some of us perceive. For example, some vendors have released 10megapixel cameras but only a very small number is meant for video surveillance use. Why video surveillance does not have high megapixels? Besides megapixels, the difference between optical zoom and digital zoom is another area of confusion. Darkness is a main issue as it is a good condition for crimes to take place. Contrary to public belief, cameras claimed to have night visions have various levels of inadequacies and not all cameras perform the same. This session will start with some basic optical principles and will address all the issues mentioned above.
Monitoring & Recording Systems
IP is an open standard for data exchange interface. Is there another open standard for IP camera footage recording, searching, playing back, and production as evidence of crime? Yes and no. The PC industry has many de facto standards set by major vendors such as Microsoft and they have been well adopted. However, the video collection, recording and play back processes are mostly proprietary at present. Some recording software packages are more expensive than others. Why the difference? This session will address 4 categories of recording packages- NAS, low cost, medium cost and high cost. There must be good reasons to justify our investments on higher cost recorders.
Why would banks, prisons, casinos, and city councils spend up to a hundred thousand dollars for installing one camera as an average price? Like cameras and recorders, there is a spectrum of implementation approaches as well. This session is meant for explaining mid to high end implementations based on proper project management procedures and it will cover 4 projects spanning from 12 to 128 cameras and $50K to $500K of project price. Whilst project management skills take years to develop and cannot be covered in this session, we will attempt to high-light a few scenarios and describe how we dealt with them.
