Select Camera

This item selects the camera to apply the changed configuration. The configurations of multiple cameras can be set by clicking check box which is in first column of each row. The changed configurations are applied to all of the cameras simultaneously when the check box of the first row which contains titles of each column is clicked. Untouched configuration items are not applied to all of the cameras.

Record Property

  • Resolution

    This item selects a video resolution to use in the recording and streaming.

  • Codec

    This item selects a video codec to use in the recording and the streaming. It is selectable between H.264 and MPEG4 codec. H.264 codec has better quality while H.264 consumes more cpu resources on using the same size of the data.

  • Frame Rate

    This item decides the number of the frames per one second to use. The bigger its value is, the softer motion is. But the quality is getting worse proportionally when higher frame is used in the same bit rate.

  • Quality

    This item selects a predefined bit rate and a key frame interval. 1 is the best quality and the bigger value is, the worse quality is. Even the same level of the quality is selected, the real quality can be different on the type of the IP camera, and selectable ranges of the quality are different.

  • Bitrate

    This item decides the quality of the video to record. The quality is specified by bit rate(bits per second). The higher bit rates are, the bigger needed disk space is. The lower bit rates are, the lower quality of video is. But the quality of the recording will not be much better above certain level.

    Bit rate should be adjusted with considering the installed place or the quality of the connected IP camera. Noisy and dynamic screens need bigger bit rate than other ones to get a similar quality to them at least.

    For reference, the quality of a common video CD is about 1400 Kbps, and the quality of an internet streaming averages 100K ~ 500K.

  • Key Frame Interval

    This item decides the interval of key frames which can be replayed with lossless in recording. Key frame needs ten to hundred times size of other frames. The larger interval of key frame is, the bigger space other frames can use, so the overall quality will be better. Conversely, the smaller interval is, the less space other frames can use, so the overall quality will be worse.

    Bigger interval of key frames makes better quality, but the delay time for seeing the next frame will be longer when the network transmission is delayed or unstable and the program have to wait next frame as some middle frames are lost. Conversely, smaller interval makes worse quality, but the delay time will be reduced.

    Also bigger interval makes the seek time longer because the playable video can be obtained when the decoding from the key frame to the desirous of frame is done on searching and playing random position. Conversely, smaller interval makes the seek time shorter.

    For reference, the key frame is used with the interval of one second for common video, of about five to thirty seconds for the internet streaming.

  • Pre-Event

    This item configures when the recording will be begun before the event in seconds.

    The real start time of the recording can be earlier than the configured one. Because correct MPEG4 video can be obtained when recording is begun from key frame, but the location of key frame may not be matched exactly. In this case, recording will be begun from the previous key frame because more recording is better than less one as the characteristics of the NVR device.

    For reference, the smaller interval of key frames is, the less error occurred.

  • Post-Event

    This item configures when the recording will be finished after the event in seconds.

  • OSD Location

    This item specifies the content and the location of OSD to display. Content can be of one of name or time. Location can be one of Top or Bottom. You can select one of pattern like Bottom [name,time].

  • OSD Date Format

    This item specifies date format of OSD to display. It is consists of combinations with four digit of year (YYYY), each two digit of month (MM) and day (DD), and sperators (-, /).

  • OSD Color

    This item picks a color of OSD to display.

  • Privacy Zone

    Privacy Zone Configuration Screen

    Figure 3.14. Privacy Zone Configuration Screen

    Sensitive area can be hidden by configuration of privacy zone.

[Note] Note
Configurations for OSD and privacy zone are enabled only in the system with capture card.

Always record cameras

This item decides whether records camera always regardless of the recording schedule or the event recording. The recording schedule should be configured and is able to adjust by clicking Schedule... button per hour when it is not checked.

Always record cameras Screen

The recording schedule can be adjusted for each camera. Recording will be done regardless of event recording in hours applied recording schedule.


Schedule Configuration Screen

Figure 3.16. Schedule Configuration Screen

The schedule manages two information. One is about date, the other is about hours. Each row above configuration screen, is one schedule. A schedule can be added, modified, removed in specified date through this configuration.

One of the created schedule applied to any devices using the schedule. For example, if a schedule applying on 1st of every month is created, all of the configuration for recording, motion detection, sensor are enabled on 1st of every month. And not just adding but also removing will applied to other devices using the schedule, so you should be cautious when you remove a schedule with the use of other device.
