There is a need for very wide-field monitoring of the sky in several branches of astronomy and astrophysics, ranging from meteor research to monitoring of optical transients and counterparts to gamma ray burst sources. The photographic very wide-field monitoring of the sky is run at the Ondřejov Observatory and other stations of the Czech Meteor Network and is sensitive enough to record stars up to 11 mag on 3–4 h exposures or 1-s flashes up to 3.0 mag over a field-of-view of 180 deg. diameter.

... A CCD device for very wide-field monitoring is also in development with sensitivity of 5.0 mag for 1-s flashes (and 10 mag for stars with 100 s exposure) over a field-of-view of 50 × 60 degrees. Both systems are briefly described and discussed.
