Following technical equipment is used by a visual meteor detection amateur network CEMeNt.

The lens has to be sufficiently wide angled and luminous - conditions so far best met by Tokina 3-8.2 mm F0.98 (IR).

KPF 131HR cammera is originally designed for building surveillance and thus requires several technical changes in order to make is suitable for usage.

The most essential change of the camera is the removal of the IR cut filter. Proceed as follows:

At the back of the camera you find a continuously shining LED, that might cause reflections from the front cover glass at night. It is therefore recommended to disconnect it during the IR filter removal.

PRC correction? Dark frame?

Before usage the camera has to be set as follows:

• exposition 1/50 s
• aperture control DC
• BW regime
• AGC to middle
• brightness ca. 75

The manual uses DFK 72AUC02 camera.

1. https://github.com/TheImagingSource/tiscamera/wiki/Getting%20Started%20with%20USB%20cameras

upgrade of the camera firmware was done according to instructions with 2 exceptions:

1. git clone https://github.com/TheImagingSource/tiscamera.git
2. sudo ./euvccam-fw -u ../../data/firmware/usb2/dmk72uc02_129.euvc

Now it is possible to see the camera in /dev/video0

2. Further it is necessary to instal ucview exactly according to instructions and then to install libunicapgtk2 from Ubuntu repository.

sudo apt-get install git autoconf libtool libgettextpo0 gettext gtk-doc-tools libraw1394-dev libpango1.0-dev libgstreamer0.10-dev libxv-dev  libgtk2.0-dev libgconf2-dev libglade2-dev libglade2.0 libglademm-2.4-dev libgstreamer-ocaml-dev libgstreamer-plugins-base0.10-dev

git clone https://github.com/unicap/unicap.git ; cd unicap
cd libunicap
./autogen.sh ; ./configure ; make ; sudo make install
cd ../libucil
./autogen.sh ;  ./configure; make; sudo make install
cd ../libunicapgtk/
./autogen.sh ;  ./configure; make; sudo make install

Compile the ucview.

git clone https://github.com/kaklik/ucview ; cd ucview/trunk
cd ucview
./autogen.sh;  ./configure; make; sudo make install
cd ../ucview-plugins/
./autogen.sh; ./configure; make; sudo make install

make; sudo make install

To test if everything got compiled fine run

ucview

Note: On some system you may need root privileges while running ucview to get your camera working.

• Signal transmission is not possible over longer distances (in orders of meters). This means, that computer has to be very close to the cameras usually under often problematic weather conditions.
• Small angular resolution of camera
• Small dynamic range

• Software for synthesized all sky camera.

Camera placed in a way that it has direct view to the ecliptic has to be protected against direct sunshine that may damage the CCD chip.

It is customary to use a timer, that would close a camera shutter during a day by means of cutting off the power source. time protection of camera from the direct sunlight

This method is not very advantageous because of the additional timer, that could be replaced by the station's computer. Moreover, the situation could be addressed using the same method as in MRAKOMĚRu4.

MetRec is a freeware software that uses its own Matrox Meteor II card (has to be purchased) to grab the signal.

UFOCapture is a proprietary software for Windows. It works with any grabbing hardware.

HandyAVI

The drawbacks of the currently used programmes for automatic detection of meteor trails could be addressed by a new OpenSource software. It is so far still just a concept - comments are found here: Redmine.

A final version of detection software should use an OPSA01A based camera as an visual data input.

Celohoblohovy kamerovy system (celooblohova kamera slozena z vice kamer) do snimaneho obrazu rovnou kreslit souradnicovou sit. Podle aktualniho casu. (Vyuzit mozna automaticke identifikace vyznamnych objektu v obrazu)

Síť Bolidozor se jistě bude snažit o využití pozorovaných dat pro detekci bolidů a jejich následné vyhledávání.

Protože kamery této stanice by měly být směrovány tak, aby zabíraly oblohu, tak pozorovaná data lze také teoreticky využít pro meteorologické aplikace. Neboť oblačnost sledovaná zespodu z menší vzdálenosti může poskytovat cenné informace o výskytu stoupavých proudů, parametrech bouřek, nebo o postupu front.

Fotometricky může být také měřena výška základny oblačnosti, nebo její tloušťka, úroveň pokrytí.

Dalším užitečným výstupem může být koncentrace prachu a aerosolů v atmosféře.
