Record: Mainstream (5MP Camera)
The functions available allow you to change the resolution, frame rate and bitrate for each camera connected. By default the recording resolution, frame rate and bitrate are automatically selected to fit in with the capabilities of the provided cameras, however you can change them if required.
· Don’t forget to click “Save” to apply settings.
· Use the “Copy” function to apply all settings to the other cameras.
· 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. Lower resolutions are available to select if required.
FPS: The number of frames per second (fps) that your NVR 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).
Video Encode Type: Your NVR utilizes two encoding methods to record video. The default method of compression is H.265. This will result in less hard drive space used when recording (before older videos are automatically overwritten) and will consume less bandwidth when using the remote playback feature in the HomeSafe View app. The second method of compression is
H.264. This is a commonly used format for recording and compressing video and is used in Blu-ray players and to broadcast TV signals. If visual quality is of importance, change this to H.264, otherwise leave the default selection.
Bitrate Control: CBR (Constant Bitrate) utilises a fixed bitrate and bandwidth to record video. This means your NVR will use the same number of bits throughout the entire recording, regardless of what is happening on-screen.
VBR (Variable Bitrate) utilises a bitrate that will increase or decrease, depending on how complex the scene is, to record video.

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 hard drive 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.
CBR: This is the default method of control that your NVR 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.
VBR: If you have cameras placed in low traffic areas, VBR is the recommended control method. As the bitrate is variable, your NVR 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 NVR will use to record video. The higher the bitrate, the more space each recording will consume on the hard drive.
The default bitrate is 4096Kbps. 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: By default, your NVR will record audio using the camera’s built-in microphone. If this is not required, click the checkbox to disable.
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.
