The near UV background level at the atmosphere has several sources. In order to evaluate the possibility to detect ultra high energy cosmic ray fluorescence signals, it is necessary to measure and monitor this UV background level. Study of space-time development of UV background level and events presented is suggested by Garipov-Khrenov in 1994-1995. By that, we construct a new fast imaging detector, a pinhole camera with the multi anode photomultiplier tuve MaPMT. In this work we present the design and construction of the pinhole camera prototype to be installed in a mountain. Also present the calibration and characterization of the MaPMT procedures used. The electronic design includes an automatic gain control to protect the MaPMT of very bright events. Finally, we present some results of events recorded in the Sierra Negra Volcano near Puebla, Mexico, located at 4300 meters above sea level.
