Remote Cameras Tested - July 13, 2006
The Border Fence Project has made significant progress after purchasing 4 cameras and testing three of them for our southern border surveillance fence. We purchased our second D-Link DCS-5300G PTZ (pan-tilt-zoom) wireless IP camera, the first mounted near Paliminas, AZ, and the second near Campo, CA, along with a Wiseman wired infrared camera and a newly purchased Linksys WVC200. The main focus now is obtaining long range night vision - the D-Link camera has proven to be very high in resolution with outstanding optics and easy-to-control robotic pan-tilt-zoom, but may need help with its 1 lux low-light sensitivity with headlights of the mobile vehicles we will place them in, or industrial motion lights on stationary positions. The Linksys WVC200 has an infrared sensor, but non-optical infrared lamps will probably be required.
The Arizona model will upload video to the Internet by Sunday, and there will be video and audio feed for the other cameras by Saturday near the California-Mexico border. Some of the snapshots from the D-Link DCS-5300G, time-lapsed during sunset in the San Bernardino Mountains, reveal the following:
Exposure at 8:20 PM, just after sunset, show some detail from 100 yards away in the background.
Exposure at 8:26 PM, with some sunlight illumination but little detail.
Exposure at 8:41 PM, pitch black with no artificial illumination or infrared sensor, only the brake light of a passing car. No infrared emitted from the heat of the car engine, only the WVC200 and Wiseman will have infrared sensing at sub-1 lux illumination.
Exposure at 5:56 AM, well after dawn. While field of view only extends 100 yards, depth of field is great and high resolution and focus expected for human subjects up to 1/2 mile away (remember zoom, and 640x480 pixel map capabilities).
