This network consists of a number of camera stations in Germany and neighbour countries.
The Network Status tab presents the location and status of the camera stations. Click on the icons for details about each station. The Equipment tab provides details about the cameras used in the network. In the Live View tab you can see a live image of the cameras which is updated every five minutes. The Fireball Archive tab shows a selection of the most spectacular fireballs recorded by our network.
Each system contains seven highly sensitive NetSurveillance NVT cameras with the SONY STARVIS IMX291 CMOS Sensor and a 4 mm f/1.0 lens. Five of them are horizonally oriented at an altitude of about 25°, camera six and seven point in northern and southern direction at an altitude of about 70° All together they cover the full sky down to the horizon.
Each camera has a field of view of about 45x80°. The cameras are recording at 25 fps and reach a limiting magnitude of about 4 mag. Maximum resolution is 25°/pixel.
Beside the cameras, the dome contains a power supply and an ethernet switch for each camera. Each camera has a black paper baffle. The dome is painted from the inside with two color layers - silver outside and pale black inside. That reduces internal reflections and the thermal influx.
Power is supplied via Power-over-Ethernet (PoE), so that the whole system needs just one CAT-6 Ethernet cable to connect it to base computer. The computer is a barebone Mini PC running Ubuntu and the AllSky7 software by Mike Hankey, which is continuously improved. Each camera provides an SD (640x480 pixel) and HD (1920x1080 pixel) video stream which are recorded by the Mini PC and analysed asynchronously.
The camera is recording meteors and fireballs 24/7, but at the moment only the nighttime recordings are automatically analysed. About 5.000 meteors are recorded per year under typical central European conditions.
