Set Event Video Parameters

Event video refers to the video cached when specific events occur. You can configure parameters (video channel, stream type, resolution, etc.) for the event video of the security control panel.

On the device list page, tap the security control panel and then log in to the device to enter the control panel page.

Tap > Event Video Settings to enter the page, and then configure the following parameters.

Video Channel

Set the channel for caching video.

Note:

Make sure you have added network cameras to the security control panel. For details about adding network camera, see Add Network Camera Channel to Security Control Panel.

Stream Type

Main Stream

Used in recording and HD preview, it provides higher resolution, code rate and image quality.

Sub-Stream

Used to transmit network and preview pictures as a video streaming with features of lower resolution, bit rate and image quality.

Bitrate Type

Constant

A constant bitrate (hence the bandwidth) is used for the video regardless of the complexity of the video scenes. Increased activities in the video scenes will result in a poorer image quality because the restricted constant bitrate doesn't reach the level to maintain sound image quality.

You can use constant bitrate when only limited network bandwidth is available.

Variable

A changeable bitrate (hence the bandwidth) is used for the video. The variability of bitrates allows videos to be recorded at a lower bitrate when there's no motion in the video scene, and at a higher bitrate when there are a lot of activities.

It is recommended that you use variable bitrates when the network bandwidth is not limited and there is a need for high quality videos. Variable bitrates provide better image quality at the expense of a higher video storage requirements as the bitrate changes with the complexity of the video scenes.

Resolution

Set the resolution for the video.

Bitrate

The higher the value is, the higher the video quality at the expense of higher bandwidth requirements.

Before Alarm

Set the time point before the alarm to start caching video.

After Alarm

Set the time point after the alarm to stop caching video.
