Version 2.0

Mobile Observation Unit

  • Axis day and night camera and outdoor housing
  • Solar module and battery bank.
  • Enclosure
  • Network bridge and antenna
  • Small fan
  • Tripod Pole

We are developing a portable surveillance system that can be deployed at remote locations. The weight of the components and ease of assembly in the field are significant considerations when accessing remote sites in difficult terrain. The camera is designed for day and night imagery, and it will enable us to determine visitation times and activity patterns of animals at remote sites. The system is currently deployed at a small water hole near the lab buildings at Boyd Center. We are developing and testing the system in this location before we deploy it at a waterhole in Deep Canyon.

Images from the camera will be saved in an image database system. The camera can detect motion and notify a researcher that an event has occurred by emailing the researcher with the current image attached to the email. The surveillance system will be the prototype for portable units that can be deployed by other researchers to remotely monitor the behavior of animals, vegetative growth, and habitat changes over time.

Remote observation of wildlife allows researchers to observe animals without the disturbance of a human presence that can alter the normal behavior of an animal. Another beneficial aspect of remote surveillance systems is the savings of time and travel expenses to remote locations by reducing the need for frequent visits to collect data that can be obtained by remote sensing.

Version 1.0

Version 1 was constructed and installed near a water feature at the Boyd Dessert Research Station. It was in a very exposed area and we learned a lot from testing this configuration. The wind load on the tripod caused the camera to loose focus on the subject because the solar panel and camera were attached to the same pole. Although the night vision of the Axis Camera was superb the interface and motion detection was hard to program for the various conditions that occurred during the day and night. The same settings that worked during the day would not be optimal for night viewing. The 100 watt solar module was very large and we were concerned about the difficulty of transport since this system is designed to be mobile. The inferred light below the camera housing worked very well at illuminating the area at night.

 

Version 2.0

With Version 2.0 we moved the entire camera construction to the water hole inside the Deep Canyon drainage. The camera is at a location that would be protected from any flash flood event. We made a number of changes to the design. We changed the camera housing to one that would be able to dissipate heat better. We chose to use a Canon camera instead of the Axis camera due to it's scheduling ability. We also installed a 75 watt solar panel instead of a 100 Watt solar panel. We are experiencing problems with the solar power due to shorter days (i.e. daylight) during the winter months and the shadows that the gorge has on the camera. The solar panel is not able to keep up with the camera with all its equipment and charge the battery. We hope to resolve these issues in the near future.

Lessons learned: 1) The camera housing and battery box require additional shading and internal fans to reduce temperatures in the enclosures; 2) Tripod mounting of the solar panel is not a viable option in high wind locations because vibration from the panel interferes with camera focus; 3) The size of the solar panel can be reduced from 100 Watt to 75 Watt to reduce the wind loading area and weight of the system; 4) The battery and wireless bridge enclosure can be smaller and lighter; 5) Real world operational power requirements and battery storage capacity will be evaluated with an aim to reduce the size and weight of the storage battery.
