Portable Sprite Observation System based on IP-Camera Leonid V. Sorokin Peoples’ Friendship University of Russia,
2
The mobile Sprite observation system is based on the IP-camera VNC748 E2 (Sony ICX-429ALL) The main purpose of making this system is the mobile decision for field observation.

MAIN FEATURES Max. exposition time - 16 sec Min. exposition time - 300 nanosec Sensitivity 0,005 Lux (F0,8) CCD SONY ICX429ALL passive cooling Auto-detecting of the lens type. (It is necessary only to plug in the lens and the camera would detect it’s type - manual iris lens, direct drive or video drive) Black level automatic regulation Gamma-correction in a range of 1.0 – 0.2 Amplification +24 dB
4
DIGITAL MODES OF SIGNAL PROCESSING AND DIGITAL OUTPUT: 10 bit ADC Digital zoom – x2 and x4 Night mode Freeze frame series mode (built-in 2Mb RAM) Titles and on-screen menu IP interface
5
IP-camera The IP-camera VNC748 E2 has the LAN 100 Base-T interface. It is possible to connect upto four cameras to one Notebook computer using the 1GB Router. In the current configuration the two cameras can be in use simultaneously.
6
Camera Driver The software provides access to all camera- settings and video capture parameters. This mobile Sprite observation system can be used for registration of TLE events –in the field, –at the open air, –during the expedition –in the conditions of the strict weight limitation.
