  1. Surveillance Web Camera David Luis W.M. Keck Observatory Akamai Internship Program Mentor: Craig Nance, Chase Reed Home Institution: University of Hawaii at Manoa

  2. Snow Build UpProblem • Dome shutter accumulation • Primary mirror • Instrument damage • Access road drift • Prevents access • Staff stranded on summit

  3. Solution Webcamera to provide quick and accurate assessment and action Solution

  4. Project Overview • Select a camera system • Set up infrastructure • Assemble, test, and install system • Test and verify camera performance

  5. Selecting a Camera System

  6. Operation Parameters in Enclosure • Temperature • 9 to 35 Celsius • Humidity • Based off humidity range of UKIRTs Sony Camera • 20-80% • Light Intensity • (50 microlux – 85klx)

  7. Camera Research • Searching the Internet • Use two cameras • Color camera for day viewing • Monochrome camera for low-light viewing • Auto-iris needed • Final Decision • Sony SNC-CS3N digital color camera for day time viewing and color information • Super Circuits PC164C Micro Super Low-light monochrome camera for low-light viewing • Moxa Vport 2110 IP converter • Sola brand power supply

  8. Camera Infrastructure

  9. Camera Infrastructure • Conduits and flex • Distribution box • Ethernet lines • Power lines

  10. Assemble, Test and Install System

  11. Camera Installation • Device testing • Tested each • Tested all at once • Device placement • Hardware mounting • Ethernet connectors and testing • Power up!

  12. Testing and Verification

  13. Testing and Verification of Performance • morning sunlight mitigation • Sunlight on both cameras • spacer between cameras and move enclosure left • night viewing • viewed twinkling stars • what it is doing now • viewing dome and small part of road • future • automatic light detecting circuit with armature
