Event-Driven Surveillance System Operation
System Operation
- Detection and Image Capture: The Autonomous Surveillance Platform (ASP) detects movement and/or heat signatures. During daylight hours, it captures images using a visible-light camera. At night, it employs an infrared flash and camera to capture images; the infrared flash operates outside the range of human vision.
- Data Storage: Captured images are stored as high-resolution files on a removable storage device within the ASP, preserving the chain of custody for all collected evidence.
- Image Transmission: A low-resolution version of each image is transmitted as an email attachment via cellular connection, reducing required bandwidth and transmission time.
- Server Processing: An application server receives the email and displays the image for evaluation using web-based software (Drawbridge).
- Geographic Display: Images are displayed alongside their corresponding latitude and longitude coordinates on a map interface.
- Image Evaluation: One or more reviewers evaluate each image and, based on their assessment, either issue a "hit" notification or remove the image from the display queue.
Why Choose ASP as a Surveillance Platform?
While ASP units are not the optimal solution for every surveillance requirement, they are highly effective assets across a wide range of situations.
Key Advantages
- Event-Driven Operation: ASPs activate only when triggered, capturing and transmitting images solely when an event occurs. This eliminates the need for continuous feed monitoring.
- Cellular Infrastructure Utilization: The system leverages existing cellular infrastructure for image transmission. Where coverage is adequate, this provides a low-cost communication solution. In areas with limited coverage, long-range antennas can be deployed to extend transmission capabilities.
- Battery-Powered Design: ASPs are engineered for battery operation and support external battery connections for extended operational life.
- Weather-Resistant Construction: Derived from wildlife cameras built for prolonged outdoor use, ASPs typically require no additional weatherproofing or environmental modifications.
- Cost-Effective Solution: ASPs are low-cost devices that continue to decline in price while simultaneously gaining new features and improved battery life.
