There are thousands of different video surveillance products on the market that work reasonably well as independent systems for people with video surveillance expertise.  However, they are difficult to use for most and cost of ownership is high.  Eyecast overcomes the drawbacks of existing video surveillance products with its cloud based video surveillance service. What is cloud based video surveillance?

Video encoders format the analog camera images into digital images that can be sent over the Internet.  There are 4 common formats or encoding techniques used for the digital images; Motion JPEG, MPEG-4, H.264, and Motion JPEG2000. Most encoders use Motion JPEG and MPEG-4.  JPEG2000 is the most efficient of the 4 encoding techniques for slow frame rate video applications (slower than full motion video which requires about 30 frames per second) like surveillance.  Video surveillance applications generally run at 1, 2, or 3 frames per second.  JPEG2000 is the most efficient of the 4 encoding techniques for video surveillance because of the algorithms it uses.

Eyecast T-400 encoder can connect up to 4 analog video cameras using BNC connectors.  The T-400 encoders take the analog video signals and encode them into digital images using the JPEG 2000 encoding technique.  The encoders mark each image with a timestamp and a digital signature that can only be deciphered by the Eyecast storage vaults.  The digitized video is transmitted from the T-400 at the customer premise over the high speed Internet connection and deposited into the video storage vault. 

Technical Detail of JPEG2000. JPEG2000 uses Wavelet transforms instead of Fourier transforms (specifically, Discrete Cosine Transforms or “DCT”) used for the other encoding techniques. Consequently, JPEG2000 is about 2 times as efficient for the same graphic image quality.  This is important when transmitting across expensive network resources and storage of large volumes of video images

Eyecast T-400

4 Port JPEG 2000 encoder for residential and business customers.

This supports upto 4 analog video surveillance cameras of any type.
There are 2 categories of cameras used for video surveillance applications; analog cameras and IP cameras.  Analog cameras are usually connected using coax cables similar to what is used for cable TV and the standard video signal generated from an analog camera is NTSC (for US) or PAL (for Europe). Since the obsolescence of the time-lapse VCR for video surveillance, all analog camera signals are converted into digital format before they are recorded or transmitted.  The process of converting the analog signal to digital is called encoding and the devices that do this are called video encoders.

Eyecast Analog Cameras. The Eyecast service works with any analog camera. As a courtesy to its customers that need to purchase analog cameras, Eyecast sells its own line of standard analog cameras. The Eyecast service is based on analog cameras and JPEG2000 encoders; the T-410, T-420, and future T-430.  There are not many JPEG2000 encoders on the market, and except for the Eyecast products, the JPEG2000 encoders that are available today are extremely expensive.

IP Cameras. IP Cameras have encoders built into the camera electronics.  Compared to analog cameras, IP cameras are very expensive.  Good quality IP cameras generally cost between $200-$900 each whereas the equivalent image quality analog cameras cost between $50-$300 each.  There are very few IP cameras that support JPEG2000. The few that are on the market cost well over $500 each.
