Advanced
In the Advanced tab, you can configure the RTSP & RTP Setting, Codec Optimization and Multi-Stream Setting.
RTSP & RTP Setting
To configure how Surveillance Station connects to the camera:
- Select one of the following from the Transport protocol drop-down list:
- Auto: Surveillance Station will automatically try to establish the RTSP connection by using the protocols in the following order: UDP → TCP → HTTP. If the camera is disconnected, Surveillance Station will use the last protocol to resume the connection.
- UDP: UDP provides lower latency and higher transfer rate. However, this protocol may deliver lower video quality through lack of network bandwidth for not having a retransmission mechanism.
- TCP: TCP provides higher video quality. However, the retransmission mechanism of this protocol may consume more network bandwidth, and delivers higher latency through lack of network bandwidth.
- HTTP: HTTP is an extension of TCP. By using this protocol, video streaming over the Internet can avoid firewall restrictions.
- Click Save to save the changes.
To configure Surveillance Station's Keep-Alive method for RTSP/RTP connection:
- Select one of the following from the Keep-Alive method drop-down list:
- Off: Surveillance Station will not transmit any RTSP commands to notify the camera to keep the streaming alive.
- OPTIONS: Surveillance Station will transmit RTSP's OPTIONS commands periodically to notify the camera to keep the streaming alive.
- GET_PARAMETER: Surveillance Station will transmit RTSP's GET_PARAMETER commands periodically to notify the camera to keep the streaming alive.
- Click Save to save the changes.
Note:
- Different camera models may use different methods by default. The default Keep-Alive method of your camera will show "(Default)" behind the option.
- You can try to configure this setting when your RTSP/RTP connection is abnormal. Changing Keep-Alive method may affect streaming stability.
- If your camera and Surveillance Station are not in the same local network, please ensure that Surveillance Station can access the HTTP and RTSP port of camera to get video stream. If Surveillance Station can only access the HTTP port of camera, please set transport protocol to HTTP.
Codec Optimization
An active codec optimization can help to save your bandwidth effectively.
Note:
- This section appears only when codec optimization is supported by your camera's streaming in H.264 or H.265 format.
To customize codec optimization:
- Tick Customize codec optimization checkbox.
- According to your camera brand, select one of the following options in the drop-down list:
- AXIS:
- disable: Streaming in original H.264 format. No extra bandwidth will be saved.
- zipstream-low: Streaming in H.264 with Zipstream-low compression. This option can realize a low level of bandwidth saving.
- zipstream-medium: Streaming in H.264 with Zipstream-medium compression. This option can realize a medium level of bandwidth saving.
- zipstream-high: Streaming in H.264 with Zipstream-high compression. This option can realize a high level of bandwidth saving.
- zipstream-extreme: Streaming in H.264 with Zipstream-extreme compression. This option can realize an extreme level of bandwidth saving.
- VIVOTEK:
- off: Streaming in original H.264 or H.265 format. No extra bandwidth will be saved.
- on: Streaming in H.264 or H.265 with Smart Stream II compression. This option can realize a bandwidth saving.
- ZAVIO:
- off: Streaming in original format. No extra bandwidth will be saved.
- better: Streaming in H.264 or H.265 with Smart Codec better compression. This option can realize a medium level of bandwidth saving.
- best: Streaming in H.264 or H.265 with Smart Codec best compression. This option can realize a high level of bandwidth saving.

To customize keyframe interval:
- Tick the Customize keyframe interval checkbox.
- Specify the number of in-between frames between two keyframes.
- Click Save to apply the changes.
Note:
- Some camera models may use second instead of frame as the unit of keyframe interval.
To enable dynamic keyframe interval:
- Tick Enable dynamic keyframe interval checkbox. This option will automatically optimize the keyframe interval to reduce bitrate for smoother streaming.
- Click Save to save the changes.
To enable dynamic fps:
- Tick the Enable dynamic fps checkbox. This option will automatically optimize the fps for smoother streaming.
- Click Save to save the changes.
