Video meteor observations
We operate two light-sensitive CCD video cameras at distant locations that point at the same volume of atmosphere at a height of about 90 km. Simultaneous meteor detections are thus possible, which enables us to compute the atmospheric path of the meteor as well as the orbital elements of the meteoroid.

Video meteor system setup for METKA:
Mintron 12V6-EX video camera
8-mm f/0.8 lens
Celeron 700
Matrox Meteor II frame grabber
First attempts in video recording the meteor activity was made on November 17/18, 2002 at our Leonid expedition in French Alps. METKA is regularly observing from Kostanjevec, Slovenia since August 12, 2003 and is operated by Javor Kac. Until May 26, 2007 the camera employed was Mintron 12V1.

Video meteor system setup for REZIKA:
Mintron 12V6-EX video camera
6-mm f/0.8 lens
Celeron 733
Matrox Meteor II frame grabber
REZIKA achieved its first light on September 7, 2005. It started with regular observations on January 23, 2006. Until March 21, 2006 it operated with a Watec 120N video camera. It is permanently mounted at Rezman Observatory and is operated by Javor Kac.

Video meteor system setup for STEFKA:
Mintron 12V1-EX video camera
3.8-mm f/0.8 lens
Celeron 850
Matrox Meteor II frame grabber
STEFKA operated under UFOCAPTURE for a few years. On September 9, 2008, the recognition software was changed to MetRec. The camera is permanently mounted at Rezman Observatory and is operated by Javor Kac.

Automatic meteor detection, position measurements and radiant associations are done with MetRec 4.0 software on both cameras. Additionally, we are using UFOCapture V2 with SMETKA, our spectroscopic video meteor camera prototype.
Multi station observations are now possible between METKA (Kostanjevec) and REZIKA (Rezman Obs). Another video station SRAKA is stationed in Velenje and is operated by Mihaela Triglav.
In 2007 March, Croatian astronomers launched a video meteor network (Hrvatska meteorska mreza) that also offers the possibility of multi station meteor observations.
Stationary video meteor stations in Slovenia (from west): Rezika, Sraka, and Metka with their respective fields of view at the height of deep-penetrating fireballs (30 km). A separate map was prepared showing coverage at 90 km altitude.
