At United Technologies, we have a motion sensing wireless video camera (called PIRCAM) that is used in residential environments as a security sensor for Burglar Alarm or Intrusion applications. If the system is “armed”, an intrusion event (burglary) will trigger the motion sensors, which then records videos and images directly on the camera. These files can then be sent to the homeowner's mobile phone, or to a third party central station where a representative can verify whether police need to be dispatched to the location.
The current product operates at 2 different frequencies, 868MHz for Alarm data and 2.4GHz for video. In order to optimize cost, we would like to make this product operate at a single frequency, 433MHz and meet European Radio requirements as defined in the European Norms specifications EN300 220. This requires that the product be adapted to operate in a constrained environment with limited bandwidth. EN 300 220 regulates the amount of transmission bandwidth needed to transmit data, and the European market has different regulations for the frequency levels that are acceptable for residential devices like our security camera.
The current operating parameters for the camera are as follows:
VGA resolution images compressed down to 27-30Kbyte file sizes with JPEG compressions.
Operates at 2 different frequencies; 868MHz for Alarm data and 2.4GHz for video.
European regulations stipulate that a device like our camera can only transmit at a 10% duty cycle at 433MHz. To send a VGA quality image at that duty cycle would take about 2 mins. We are hoping to get that value down to 20 seconds or less.
1) How do we compress the images produced by our camera to an even smaller file size?
2) How do we get these files to end users without violating the rules set by EN 300 220 regulations Europe? (keep the 10% duty cycle in mind).
3) Convert the camera to make it operate at 433MHz frequency that is suitable for the European market standards.
4) Include any mockups, research, tests, or other data you produced to come to your solution
Criteria: We can provide a working camera that can be adjusted and re-engineered as you work toward a solution
