The technical starting position
A meter cabinet is often logical for cables, but can be hot or difficult to reach. An open living room cabinet is more accessible, but also makes the recorder visible.
A recorder location should not only be out of sight; maintenance, heat and the route of camera and network cables also play an equally important role.

Check space, ventilation, power, network, physical security and the possibility to reach a disk or cable. Also determine who may have access to the recorder.
Choose a dry, accessible place with stable power and sufficient air circulation. Consider physical shelter when a location is easily accessible to unauthorized individuals.
Check temperature, recording and network after a normal usage period. Test whether a manager can safely reach the recorder without blocking cables or ventilation.
Only if heat dissipation and accessibility are sufficient.
