Installations/ConnectionsThis camera is designed to be installed on a ceiling.Before starting the installation/connection, prepare the required devices and cables.Before starting the connection, turn off the power of the devices including the camera and the PC or disconnect from the12 V DC power supply.InstallWhen installing the camera on a ceiling, there are two methods; wiring through a hole in the ceiling (☞ page 16) and wiringthrough a cable guide (unnecessary to make a hole in the ceiling) (☞ page 20).Important:• Procure 4 screws (M4 or M6) to secure the camera mount bracket (accessory) to the ceiling according to the materialof the installation area. In this case, wood screws and nails should not be used.When installing on concrete ceiling: Fix with anchor bolts (M6).(Recommended tightening torque: M4: 1.6 N·m {1.18 lbf·ft}, M6: 5.0 N·m {3.69 lbf·ft})• Required pull-out capacity of a single screw/bolt is 196 N {19.99 lbf} or more.• If a ceiling board such as plaster board is too weak to support the total weight, the area shall be sufficiently reinforcedor the ceiling mount bracket for the camera WV-Q105 (option), or the ceiling embedding bracket WV-Q155S/WV-Q155C (option), shall be used.• When using an outdoor housing to install the product on the ceiling, use the inner cover (provided with WV-Q157 orother optional mount brackets). That can avoid the shape of the camera from reflecting on images.• When using a mount bracket (option) or inner cover (provided with WV-Q157 or other optional mount brackets), referto the operating instructions of the bracket in use.• Remove the cover film from the transparent part of the dome cover after the installation is complete.• Be sure to install the safety wire to prevent a fall of the camera resulting in injury or accidents in case the mount brack-et (accessory) comes off.
