Answer

The EMV1200 HD / EMV800 HD / EMV400 HD series mobile DVRs supports multiple camera types including 1080p, 720p, 960H and D1 cameras. To connect different types of cameras to the mobile DVRs, there are some tips and restrictions. Please refer to the indications below:

Tips and restrictions when connecting cameras to the mobile DVR:
1. The mobile DVR can automatically configure itself as NTSC or PAL. To do this, connect a camera to any channel of the mobile DVR. The mobile DVR will detect the first connected    camera format (NTSC or PAL) and then automatically configure itself to the detected format from the first connected camera. For example, if the format of the first connected camera is    NTSC, the mobile DVR will configure itself to NTSC format.
2. All video inputs are compatible with all resolution types of cameras, such as 1080p, 720p, 960H and D1 cameras (HD-TVI / HD-CVI / HD-SDI cameras are not supported).
3. If you want to connect different types of camera (1080p, 720p, 960H or D1) to the mobile DVR, please follow the rules as below:

♦ Make sure the same type of cameras should be connected to the same pair of video inputs. For instance, pair A for 1080p cameras, pair B for 720p cameras, pair C for D1 cameras. The pairs of video inputs are set as: channel 1 and 2 as a pair; channel 3 and 4 as a pair; channel 5 and 6 as a pair; and so on.

Example: Connect the same type of cameras to the same pair of video inputs. So the camera live views will be displayed on the monitor as illustrated below.

Note: If you connect two 1080p cameras to a pair of video inputs (say CH1 and CH2), both of the maximum live resolution will be displayed as 1080p; however, the maximum recording resolutions on CH1 and CH2 will get lower down to 1080pH (960 x 1080).

♦ If you connect different types of cameras to the same pair of video inputs, it will only display the camera live view with the higher resolution. As to the channel of lower resolution camera, there will be no live view and a status icon will be displayed.

Example A: If you connect a 1080p camera to CH1 and either a 720p, 960H or D1 camera to CH2, only 1080p stream will be displayed, and CH2 will have no live view but a status icon  that indicates you to connect a 1080p camera to this channel instead.

Example B: If you connect either a 720p, 960H or D1 camera to CH1 and a 1080p camera to CH2, only 1080p camera live view will display, and CH1 will have no live view but a status icon  that indicates you to connect a 1080p camera to this channel instead.

Example C: If you connect a 720p camera to CH1 and either a 960H or D1 camera to CH2, only 720p camera live view will display, and CH2 will have no live view but a status icon  that indicates you to connect a 720p camera to this channel instead.

Example D: If you connect either a 960H or D1 camera to CH1 and a 720p camera to CH2, only 720p camera live view will display, and CH1 will have no live view but a status icon  that indicates you to connect a 720p camera to this channel instead.
