Onssi on why IP surveillance makes sense

April 29, 2009

Remember when you purchased your first digital camera?  It was easy (sort of).  You could take as many pictures as you wanted.  And purge the crappy images later.  There was instant preview.  You could email the pics without a scanner or a trip to the photo store.  Pictures went from special occasions to daily occurrences.  This same thing is happening in surveillance.  As people transition from analog  video to digital video and IP technologies, a whole new world emerges.  Images are higher quality.  You can make out faces, nail polish color and name badges.  You can act, or react immediately based on the footage.  You can analyze the footage.  You can view the footage remotely:  from home, on your mobile, or when you are out and about.  Each of these features of digital video are opening up new opportnities for physical surveillance.

From Security World Magazine:

Why is everyone migrating to intelligent IP video surveillance?

Intelligent network-based video surveillance technology based on Internet Protocol (IP) can transform yesterday’s analog CCTV system into tomorrow’s feature-packed security management tool. And it is available today. The technology infuses the power of video into a company’s security infrastructure and delivers value not just to the security department, but potentially — through open architecture connectivity — to almost every part of a business and even to the bottom line. No wonder everyone is migrating to IP-based intelligent video surveillance. The economic benefits are as clear as the numbers on a ledger sheet — although these benefits are sometimes not clearly communicated to company management. This article will describe the basics of IP video surveillance — the technology and its security benefits — with an emphasis on its costs and its value to transform security.

Video tutorial on designing a video security system

April 14, 2009

Need some help designing a video security system?  Check out this video from GSP America.

Here are 6 questions from the video on what to look for and what to ask:

  1. What type of cameras should I use?
  2. How should I connect the cameras to the video management system?
  3. What type of video management system should I use?
  4. What sort of video analytics should I use?
  5. How should I view my surveillance video?
  6. How should I integrate video with my other systems?

I’d add the following questions to consider during the design phase.

  • How much analytics can your video management system process at once?
  • Does your system have enough bandwidth to support all of the simultaneous recording activity you expect?
  • How long do you need to keep your footage stored on a live system?  Do you also need to archive your footage to a secondary system later?
  • How can you ensure the system you buy today will support your needs tomorrow?
  • Are there any regulations or retention policies that impact how long you need to keep your footage?  How can you guarantee you are meeting these requirements, and ensure your video is safe and protected?

Bytes, Cameras, Action!

February 10, 2009

You just installed two dozen high resolution cameras in your surveillance system. You got your video management software, your video servers, and your storage. So what else do you need to consider?

Bytes: Define your storage requirements upfront. You don’t want to exceed storage space two months down the road. Here are some critical factors that impact storage decisions: data traffic, redundancy, archive time, and processing power and speed.

Cameras: Choose the right cameras for your project and make sure all the key components are compatible with each other. Also, determine if the management software supports what you need. The type of camera you use will impact the amount of storage you require, so consider these:

  • Image size
  • Frame per second (FPS)
  • Compression type
  • % of compression
  • Amount of motion
  • Event recording vs. continuous recording
  • # of recording hours per day

Action: Now put these pieces to work. The key to designing a flexible surveillance solution is to choose a system that is scalable and will grow as your needs grow. Don’t lock yourself into a proprietary system that will limit you from customizing and upgrading. Learn how to avoid these limitations with this video.

H264 or MPEG4 for Surveillance Applications?

January 27, 2009

I was looking in on the Surveillance Technology Group on LinkedIn and found this interesting discussion:

Frank Miko, Cheatham & Associates:

What are your thoughts on H264 as compared to MPEG4 or other compression formats?

Responses:

Craig Waltzer, Aventura Holdings

My company utilizes the H.264 algorithm because it utilizes significantly less bandwidth (better transport) and smaller file sizes (more storage capacity) than MPEG-4. … The picture quality comparison between MPEG-4 and H.264 is not distinguishable by the naked eye. … H.264 video can not effectively be played in reverse.

What’s your take, which compression do you prefer?  Have you uncovered a good way to add storage to your surveillance system, so storage capacity is irrelevant? Take the poll.

H264 compression is growing fast on the consumer side, and looks to replace the MPEG-4 encoding in the next couple of years.  More importantly, the upgrades in general purpose operating systems (Windows, OSX, Linux) and computer hardware will allow our computers to take advantage of the CPU power in the graphics cards, and offload this processing from the standard CPU.  Look for these features to trickle down into DVR systems soon, and eliminate the compatibility issues between H264 cameras and DVR systems.  With the growth in newer IP technologies overseas, we in the US don’t want to be left in the dust with low resolution digital video or analog CCTV systems.
