Configure the Recording Mode „ Continuous Recording Settings 1 Click [Continuous Recording] in the recording mode list and select the check box. 2 Configure the video recording settings. (1) (2) (3) (4) (5) (6) (7) (1) [Aspect Ratio] Specify the aspect ratio ([4:3] or [16:9 (4:3)]). If you select [Not specified], the camera's aspect ratio setting is used for recording. (2) [Resolution] Specify the resolution when [Aspect Ratio] is set to [4:3] or [16:9 (4:3)]. If you select [Not Specified] for the [Resolution], the camera's resolution setting is used for recording. (3) [Video Format] Specify the video format ([JPEG], [MPEG-4] or [H.264]). The available formats depend on the camera model. (4) [Maximum Frame Rate] Specify the maximum frame rate (number of frames recorded in one second) in the range from 0.1 to 30 frames per second (fps). (5) [Record audio if available] Select this check box if you want to record audio together with the video. (6) [Advanced] Displays the [Advanced Recording Settings] dialog box. For details, see "Configure the Advanced Recording Settings" (p. 88). (7) [Use the recording-mode stream] Enable the recording stream function. With this function, the camera temporarily stores the video in its own memory before sending it to the Storage Server. This can help reduce the effects of non-uniform network traffic (jitter). Important • The three video receive sizes in each set, for example [480x270 (320x180 / 320x240)], in the [Video Receive Size] submenu are sizes that correspond to the category [1080p category (720p category / 4:3 category)], respectively. Which of the three sizes that is used is determined by the size set in [Video Size Set] for the camera. • The video size is set to "480x270" when [480x270 (320x180 / 320x240)] is selected in [Video Receive Size]. To set "320x240," select [4:3] in [Aspect Ratio] and select [320x240] in [Video Receive Size]. • You can save JPEG images of the recorded stream to an SD memory card in the camera using [Use the recording mode stream] if the stream could not be distributed due to a network failure. Images are saved at a frame rate of 1 fps. For details, see the camera manual. • The size of the recording data increases as the resolution and frame rate become higher. Make sure there is sufficient hard disk space available before specifying a higher resolution and frame rate. • If you select [MPEG-4] or [H.264], the [Storage Server] option in [Detect Motion Using] cannot be selected. • Even if the [Record audio if available] check box is selected, audio will not be recorded if the audio sending function has not been activated on the camera. If you schedule a recording, make sure the audio sending function on the camera has been set to [Enable]. Note • If you select [MPEG-4] or [H.264] for the [Video Format] setting, the [Aspect Ratio] and [Maximum Frame Rate] settings cannot be changed. The settings on the camera are used for recording. Only supports [JPEG] for the [Video Format]. • It may not be possible to record at the specified frame rate or recording may pause intermittently, depending on the load on the Storage Server CPU or the hard disk. • Recording may be performed at lower than the specified frame rate, depending on the number of Viewers that are accessing the camera, the load on the camera and Storage Server, variation in network traffic, and the environment at the time of recording. • The maximum frame rate is 5 fps. • Audio recording is enabled when the recording mode is selected. You cannot schedule audio-only recording. • If [MPEG-4] or [H.264] recording format is used, the recorded audio will not be in sync with the recorded video. If [JPEG] recording format is used, the recorded audio will be in sync with the recorded video for the most part, however it is not guaranteed that it will be completely in sync. 82
