Event Driven Surveillance
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. This process preserves the chain of custody for evidence collected by the ASP.
- Image Transmission: A low-resolution version of the image is transmitted as an email attachment via cellular connection. This approach reduces the 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 with their corresponding latitude and longitude coordinates on a map interface.
- Image Evaluation: One or more viewers evaluate each image and, based on their assessment, either send 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 possess the capability to function as excellent surveillance assets in many situations.
Key Advantages
- Event-Driven Operation: ASPs are designed to activate only when triggered, capturing and transmitting images solely when an event occurs. This eliminates the need for constant monitoring of the feed from ASP units.
- Cellular Infrastructure Utilization: The system leverages existing cellular phone infrastructure for image transmission. In areas with adequate cell coverage, this provides a low-cost communication solution. In regions with limited cellular coverage, long-range antennas can be deployed to improve transmission capabilities.
- Battery-Powered Design: ASPs are engineered for battery operation and include features that support external batteries for extended operational life.
- Weather-Resistant Construction: Since ASPs are derived from wildlife cameras designed to function in outdoor environments for extended periods, they typically require no additional modifications or weatherproofing.
- Cost-Effective Solution: ASPs are low-cost devices that continue to decrease in price while simultaneously adding new features and extending battery life.
