what types are there
What types are there…
  • JPEG - Joint Photographic Experts Group
    • Still image compression, intraframe picture technology
    • Motion JPEG (MJPEG) is sequence of images coded with JPEG
  • MPEG - Moving Picture Experts Group
    • Defined by ISO/IEC, several standards MPEG1, MPEG2, MPEG4 and now MPEG4-10/H.264
  • H.261/H.263/H.263+ - Videophone/conferencing
    • Low to medium bit rate, quality.
  • Ionit:
    • Intelligent foreground and background algorithm utilizing DSP chip technology.
    • Designed for video surveillance
frame to frame technology

Compressed (50)(22 KB, 12:1)

Uncompressed(262 KB)

Compressed (1)(6 KB, 43:1)

Frame to frame technology

Each frame taken as a whole, and stripping out the “less important information”, letting your eye fill in the details.

Results: “Boxy effect”

what is dynamic
What is Dynamic?
  • Non Dynamic Compression: complete scene

The 1st frame is 3 Kbytes; the 2nd Frame is 3 Kbytes; the 3" Frame is 3 Kbytes This stores a total of 9 Kbytes

  • Dynamic Compression: what’s changing

The 1st frame is 3 Kbytes; the 2nd is only 0.6 Kbytes; the 3rd is only 0.6 Kbytes.3Kb + 0.6 KB + 0.6KB = 4.2 Kbytes, important for storage, streaming & processing

no compression big problems
No Compression = Big problems

Problem: How to store 11,520 hours of video

16 cameras 24/7 recording 15 fps for 30+ days

Large file sizes = Increased system & network failure

Clearly the need to compress video!

superior compression
Superior Compression

Compression is needed to do the following

  • Increase System stability

Less data= less work

  • Increase video storage
  • Lower bandwidth usage & protect the network.
  • Faster search & retrieval: files are smaller/less taxing on the system




Real solutions for your customers.

Not problems.

Compression Ratio

why ionit
Why Ionit?
  • STORAGE: MINIMUM of 30 days of 24/7 recording at 640x480 and 240 ips, GUARANTEED!
    • Why record 24/7? It’s just as important to prove nothing happened as it is to prove something did.
  • STREAMING: send video over I.T.'s bandwidth, they don’t mind.
  • STABILITY: less processing, less hardware, less heat = less failure, period.
  • SERVICE: 3 Year advanced parts warranty.
  • DVR’s
    • Embedded solution
    • Windows Based solution
    • Cameras: PTZ’s
    • Accessories, enclosures, UPS’s...
