What is Motion Jpeg (a.k.a MJpeg / M-JPEG)?

Motion JPEG (M-JPEG) is a video codec where each video field is separately compressed into a JPEG image . It is also commonly used by IP based video cameras via HTTP streamsMozilla based browsers like Netscape and Firefox have native support for viewing these streams whereas Internet Explorer does not.

What is H.264?

H.264 , MPEG-4 Part 10 , or AVC , for Advanced Video Coding, is a digital video codec standard which is noted for achieving very high data compression . The intent of the H.264/AVC project was to create a standard that would be capable of providing good video quality at bit rates that are substantially lower (e.g., half or less) than what previous standards would need (e.g., relative to MPEG-2 , H.263 , or MPEG-4 Part 2 ), and to do so without so much of an increase in complexity as to make the design impractical (excessively expensive) to implement.

What is an mBox?

An mBox is a small device measuring 145x120x85mm, that is capable of receiving video input from an analogue video source and compressing the video into mJpeg format which is then streamed back to the mVision server.

Additional accessories include an all-weather casing and a vehicle-compatible power adapters, which are available upon request.

The mBox is currently compatible with GSM/GPRS and CDMA 1X networks only.

Why is a GSM/GPRS modem required?

A GSM/GPRS modem is required to for the mVision (mBox) configuration. The primary role of the modem is to send a "Wake Up" trigger to the mBox, this will instruct the mBox to dialup and connect to the internet. Once online, the mBox receives it's instructions via the IP layer. The modem's secondary role is to send SMS/MMS alerts as and when triggered.

What kind of mobile devices is can be used to view video streams?

In order to support the mVision Mobile Client, the mobile device has be Java enabled with MIDP 2.0. An alternative, for devices that do not support MIDP 2.0, would be to deploy a WAP gateway for a more friendly access to view video streams on the go.

Hence viewing is not limited to only mobile phones, devices such as a PDA with Internet connection can be used as well.
