This manual offers reference material and general information about the basic operation, maintenance, and troubleshooting of the Dahua Multi-Sensor Panoramic Camera. Read, follow, and retain the following safety instructions. Heed all warning on the unit and in the operating instructions before operating the unit.
Ensure a service technician uses replacement parts specified by the manufacturer, or that have the same characteristics as the original parts. Unauthorized parts may cause fire, electrical shock, or other hazards. Dahua is not liable for any damage or harm caused by unauthorized modifications or repairs.
• Dahua recommends the use of a thunder-proof device in concert with the unit. • Do not touch the CCD or the CMOS optic sensor. Use a blower to clean dust or dirt on the lens surface.
• Video loss is inherent to all digital surveillance and recording devices; therefore Dahua cannot be held liable for any damage that results from missing video information. To minimize the occurrence of lost digital information, Dahua recommends multiple, redundant recording systems, and adoption of backup procedure for all data.
2 Unpacking This equipment should be unpacked and handled with care. If an item appears to have sustained damage during shipping, notify the shipper immediately. Verify that all the parts listed below are included. If an item is missing, contact customer support or your local representative.
3 Installation and Configuration 3.1 Framework and Dimensions The following figures show the dimensions of the device in mm (in.). These images are intended as a reference only. Figure 3-1 3.2 Wiring The dome camera includes: Wire Color Connection Power 24 VAC Yellow/Green Earth Ground...
3.3 Alarm Setup Certain devices support alarm inputs and outputs, check your specific device for alarm capability. Alarm Input Refer to Figure 3-3 for alarm input configuration. The device collects that status of the alarm input port when the input signal is idle or grounded. If the input signal is connected to the 3.3 V or it is idle then the device receives the alarm input signal.
Alarm Output – Switch Application The alarm output drives the external circuit, with a maximum current of 30 mA and a maximum voltage of 5 V. It is recommended to add a relay if the circuit exceeds the maximum values. Figure 3-4...
A readily accessible 2-pole disconnect device with a contact separation of at least 3 mm must be incorporated. Note: Dahua recommends attaching a “drip loop” (flex or hard conduit) during installation to ensure condensation does not form in the mount or the conduit.
3. Use the hex key to remove the three screws that secure the dome bubble to the camera housing. 4. Remove the packing material around the camera. 5. Replace the bubble. Transmission distance results verified by real-scene testing in Dahua's test laboratory. Actual transmission distances may vary due to external influences, cable quality, and wiring structures.
4.3 Mounting the Camera into a Ceiling 1. Determine the placement of the camera, then affix the ceiling installation template to the location to mark the location. 2. Cut a hole in the ceiling according to the template. 3. Connect the composite cables from the camera to the external cabling and then carefully push the cable through the hole and into plenum.
