Abstract: A protective housing for surveillance video cameras has a tubular housing shell (1) which can be slid back and forth in a telescoping manner relative to an equipment carrier (2), which can be installed in a fixed position. The housing shell (1) and the equipment carrier (2) are connected by a sliding guide piece (4), which forms a pivot bearing (S-S) after the shell has been pulled out as far as it can go to allow the housing shell (1) to pivot around the end of the equipment carrier (2). To facilitate installation and to avoid corners from being cut off the viewing angle during installation and adjustment, both the housing shell (1) and the equipment carrier (2) are provided with guide grooves (11, 15), arranged in pairs; and the sliding guide piece (4) is guided by means of first and second projections (18, 19) so that it can slide relative to both the housing shell (1) and the equipment carrier (2) in their guide grooves (11, 15).
