3The camera’s external INPUT interface allows you to connect a device (such as sensors, motion detectors, etc.) that can be used to trigger the camera’s imagebuffering and transferring features (see Section 2 Using Triggers to Buffer and Transfer Images in the Operating Instructions on the CD-ROM).The external INPUT interface has 2 terminals.Mounting the CameraImportant Information Regarding Camera MountingPlease read the following information before mounting the camera. Consult anauthorized dealer for mounting.Caution• Make sure you attach the safety wire when mounting the camera on aceiling to prevent the camera from falling.Note• The camera is intended for indoor use only and should not be mountedoutdoors.• The included screws are for use with wooden ceilings only.• Use screws that are appropriate for the material of ceiling.• If the ceiling or wall material is mortar or concrete, see page 4 “Whenmounting the camera on a concrete or mortar ceiling”.• Do not drive the screws into a soft material. Drive the screws into a secure,25 mm (1 inch) thick area of the ceiling or wall, such as a crossbeam,otherwise the camera may fall. If there is no crossbeam, place a board onthe other side of the ceiling or wall to make sure the camera is securelymounted.• The pull-out strength of the installation area must be at least 294 N (30 kgf)per screw.• Mount the camera to a flat horizontal ceiling surface or vertical wall. (Thecamera cannot be used on surfaces that have more than a 15° slant.)• The camera cover must be removed in order to insert or remove the SDmemory card.• The camera’s MAC address and serial number are printed on the bottom ofthe camera and are needed in order for camera configuration andmaintenance. Make a note of both of them before mounting the camera.• Mounting and cabling instructions described in this document followgenerally accepted guidelines suitable for residential installations. In someareas, commercial and industrial installations are regulated by local or stateordinances. For such installations, contact your local building department orbuilding inspector for more details.• Camera images can be viewed in relatively dark areas, however, imagequality decreases when viewing dark images. We recommend usingsupplemental lighting for best results.• Prolonged exposure to direct sunlight or halogen light may damage thecamera’s image sensor. Mount the camera appropriately.• Do not directly touch the lens cover. Clean the lens cover with a dry and softcloth if necessary.• When mounting the camera, make sure to wrap the AC adaptor cord (ifused) around the hooks as shown to ensure secure connections.• Adjust the installation location and the direction the camera is facing whilewatching the actual camera image being displayed on a computer screen.Mounting the CameraWiring without making a hole for cables in the ceiling or wall1. Open the screw covers, loosen the screws, and remove the cameracover. (For BB-HCM701CE/BB-HCM705CE: When loosening thescrews, use the included bit.)2. Secure the safety wire to the camera using screw B (included) andwasher B (included).• Make sure you attach the safety wire when mounting the camera on aceiling to prevent the camera from falling. (Recommended torque0.6 N·m {6.1 kgf·cm})3. Connect all necessary cables (AC adaptor, LAN, etc.).4. Secure the camera to the ceiling or wall using screws A (included).• Do not drive the screws into a soft material. Drive the screws into asecure, 25 mm (1 inch) thick area of the ceiling or wall, such as acrossbeam, otherwise the camera may fall. If there is no crossbeam,place a board on the other side of the ceiling or wall to make sure thecamera is securely mounted.Connecting External SensorsNote• Do not push strongly on the external INPUT interface with the pointedobject. The external INPUT interface may get stuck into the unit, and youmay not be able to use it.Terminal Description1 External sensor input. The camera can be triggered by either an opencircuit or a GND short-circuit.2 GND terminal.Caution• The external INPUT interface is not capable of connecting directly todevices that require large amounts of current. In some cases, a custominterface circuit (customer-provided) may have to be used. Seriousdamage to the camera may result if a device that exceeds its electricalcapability is connected to the external INPUT interface.• Low voltage/current circuits and high voltage/current circuits are used inthe camera circuit. All wiring should be performed by a qualified electrician.Incorrect wiring could damage the camera and cause a fatal electric shock.External INPUT interfaceDoor Sensor (Alarm)CameraCircuit Diagram Example12Cable hookN Ceiling N WallScrew covers (3 places)Safety wire holeScrew B(Length: 10 mm [3/8 inches],Body diameter: 2.6 mm [1/8 inches])Washer B(Inside diameter: 2.6 mm [1/8 inches]) Safety wireScrews A (3 pcs.)(Length: 20 mm [13/16 inches],Body diameter: 4.0 mm [3/16 inches])MicrophoneIndicatorFront MicrophoneIndicatorScrews A (3 pcs.)(Length: 20 mm [13/16 inches],Body diameter: 4.0 mm [3/16 inches])Up
