Record: Mainstream. Swann 1080P 8CH X4 CAMERA DVR 1TB KIT, SWDVK-846804SL-EU

Record: Mainstream

The functions available here allow you to change the resolution, frame rate and bitrate for each camera connected. By default the recording resolution is automatically selected to fit in with the capabilities of the provided cameras.

· Don’t forget to click “Save” to apply settings.

· Use the “Copy” function to apply all settings to the other cameras.

· Click the “Default” button to revert back to default settings.

· Click the “Close” button to exit the Main Menu.

Channel: Select a camera that you would like to edit.

Resolution: By default the recording resolution is automatically selected to match the capabilities of the provided cameras. If you have an older analogue camera connected, lower the resolution to “960 x 480” for NTSC and “960 x

576” for PAL, to match the camera’s recording capability.

FPS: The number of frames per second (fps) that your DVR will record. The default is 15fps, however you can change this if needed. In the HomeSafe

View app, you can select “Mainstream” in Live mode to view your cameras.

Lower the frame rate if you’re having issues streaming to your mobile device

(lowering the frame rate to 7fps for example, will reduce the bandwidth required without sacrificing image quality).

Bitrate Control: CBR (Constant Bitrate) utilises a fixed bitrate and bandwidth to record video. This means your DVR will use the same number of bits throughout the entire recording, regardless of what is happening on-screen.

VBR (Variable Bitrate) utilises a bitrate and bandwidth that changes when your DVR is recording. The bitrate will increase or decrease depending on how complex the scene is.

Which method should I choose?

Scene complexity can vary significantly over several hours of recorded video, and the bitrate you select for recording will have an effect on image quality, bandwidth consumption, and storage. A complex scene with moving action, such as traffic on a city street, or a scene with a lot of contrasting colors, will affect image quality and bandwidth consumption more than a less complex scene with little action or movement.

As MicroSD cards have limited storage capacity when compared to a hard drive, the maximum bitrate that can be selected is 2048Kbps. If a hard drive has been connected, the maximum bitrate available is 6144Kbps.

· Use the “Copy” function to apply all settings to the other cameras.

· Click the “Default” button to revert back to default settings.

CBR: This is the default method of control that your DVR will use to record video. If you have cameras placed in high traffic areas, CBR is the recommended control method. As the bitrate is fixed, the image quality will be consistent throughout the entire recording. This will assist when identifying people or objects.

VBR: If you have cameras placed in low traffic areas, VBR is the recommended control method. As the bitrate is variable, your DVR can use a lower bitrate if there is little to no movement detected. This will result in a lower recording size as well as a lower bandwidth requirement.

When choosing VBR, you can select the recording quality that will define the variable bitrate used. You can select from lowest to highest.

Bitrate Mode: You have the choice of selecting a predefined or user-defined bitrate. For most instances, the default selection will be suitable.

Bitrate: The amount of data that your DVR will use to record video. The higher the bitrate, the more space each recording will consume. The default bitrate is 1536Kbps (4096Kbps when recording to a hard drive). Change the bitrate if you’re having issues streaming to your mobile device via the HomeSafe View app (when selecting “Mainstream” in Live mode to view your cameras). Decreasing this will consume less bandwidth when streaming.

Audio: Click the checkbox if you have an audio source connected to the DVR’s audio input(s) (for 8 channel models, this option is on camera input 1 only).

Please note: Selecting the appropriate recording settings is dependent on camera location, lighting conditions and the level of quality required.

Some experimentation is recommended to select the best settings.
