Mouse, Audio Input, Output and Bidirectional

Mouse

The included USB mouse will only operate if connected to the DVR through the USB port on the rear of the DVR (Item number 8 in Picture 2-2). The USB port on the side of the DVR’s screen is only for external USB storage devices.

Audio Input, Output and Bidirectional

Audio input and output is also handled through the BNC dongle. Each channel, including the output channel, is labeled on the lead itself. To receive audio signals, you must have a camera with built-in microphone or a separate microphone located near the camera.

Cameras

Conventional CCD or CMOS cameras are connected to the DVR through the Audio/ Video port (Item number 7 in Picture

2-2) via the A/V dongle included with the system. The dongle shown in Picture 2-3has eight Video In plugs (black) for cameras and four audio input plugs (yellow). The extra black and yellow plugs are Video Out and Audio Out respectively. The dongle that comes with your DVR may differ in the number of plugs depending on your DVR’s features.

Normal output through the BNC audio out channel is usually over 200mv 1KΩ. It can directly connect to an active sound box or amplified speaker. There is also an earphone jack on the right side of the unit above the USB port which allows you to listen to any audio feeds without additional equipment.

The cameras will also need to be connected to a power supply – whether the power supply included with the cameras or a power distribution panel. For best results, both the DVR and the camera power supply(ies) should share the same electrical grounding.

For cable runs longer than 200 feet, cable runs within walls, or in areas where there is electromagnetic interference, you should use high-quality shielded RG59 cable. RG6 cable should be used for runs exceeding 800 feet and fiber optic cable should be used when distances exceed 1,800 feet. In circumstances requiring cameras to be positioned over 200 feet from the DVR, the camera’s power supply should be located closer to the camera.

Video Output

This DVR supports video output to two external monitors simultaneously through the HDMI port (Item number 9 in Picture 2-2) along with the Video Out cable on the dongle. Use of the HDMI output requires an HDMI cable (not included) along with a monitor or television capable of processing 720i high-definition signals. The BNC Video Out lead on the dongle is labeled as such. For output through the dongle, you will need to use a signal converter box to connect to a VGA monitor or a television with VGA inputs.

The audio out lead can alternately be used to allow you to communicate with someone near one of your cameras. This will require placing a powered speaker in the same location as that camera. There also needs to be a microphone co-located with that camera if not built into the camera itself. You will also need to connect a microphone to the microphone port on the side of the DVR and use the headphone/speaker port to hear the audio feed.

Using the DVR as a Computer Monitor

The DVR’s LCD screen can be used as a computer monitor by plugging in a VGA monitor cable from a computer into the VGA In port (Item number 6 in Picture 2-2) on the back of the system as you would with any regular computer monitor. This can be useful in the short term when setting up network access of the DVR, or it can be a long-term solution such as saving space or to hide the purpose of the DVR. You will not be able to use the screen to view input from the computer and the cameras at the same time. External video input from a computer will override the DVR’s video. You will need to install a monitor switch box between the computer and the DVR to manually “turn off” the computer’s video feed, allowing the system to display normally.
