System Integration for a Network Surveillance Camera

 

 
The challenge
The challenge was to develop end-to-end solution on a multi-processor environment for the Network Camera and provide the client with enhanced feature set and time to market advantage.
 
The solution
Wipro approached the solution as follows:
A dedicated team of Wipro engineers studied network camera and other similar products already available in the market to understand the features offered by competitors and came up with a comprehensive list of “features” for the product to be developed. This information was shared with the client and thereby enhanced the features for the product.
Further, the Wipro team made value added propositions to the client based on the results of the study and Wipro’s accumulated expertise. All this resulted in a robust design incorporating the “enhanced features” of the product.
Wipro’s reusable building blocks of MPEG-4 video encoder, RTP and RTSP were used to provide “live MPEG4 streaming” solution. This cut the development cycle and the time gained was used in further customizing the solution.
Wipro provided support for electromechanical sensor, motion detection, mailing and FTP of alarm images and various other features for remote monitoring.
Wipro provided software workarounds for issues/problems in the client supplied hardware.
Wipro provided solutions to circumvent bugs in the third party OS used.
 
The Components
The building blocks of a typical Network Camera are shown below:
Wipro’s MPEG-4 Video streaming solution interoperable with QuickTime 6 players includes the following components, which helped the client reduce development cycle time:
MPEG-4 video encoder ported on TMS320DSC24
Networking protocols like RTSP and RTP to stream to standard MPEG-4 player like QuickTime
RTP packetization as per RFC 3016
MPEG-4 Video decoder for playback ported on TMS320DSC24
Support for Video packetized MPEG-4 bit stream
MPEG-4 Systems layer
