Make sure the device uses the default settings.Īdd the following as overlays in the device: The dedicated video memory should be more than 1 GB.Īlways use our recommended browsers, see AXIS OS Portal. Make sure you use a computer with a good graphic card. There are some things to consider before you start your recording.Therefore, we rely on recordings from the device to troubleshoot. In some scenarios the latency or lagging cannot be noticed in the system logs. You can also find relevant information in the Troubleshooting guide for image quality. Hardware decoding setting in AXIS Camera Station.įor more information about latency, go to our White paper portal and search for latency. If you have a high-performance graphics card, Hardware decoding is a good way to improve the performance and reduce the CPU usage, especially if you stream high-resolution video. Turn on Hardware acceleration which is a feature in video management systems and clients that moves all graphics and text rendering from the CPU to the Graphics Processing Unit (GPU). Try the following settings in your client: Any modification of the settings may impact the video fluidity negatively. The default settings are a sort of sweet spot where the image settings and stream settings are optimized and balanced to provide a fluid video stream in most of the common scenes and scenarios. In general, we recommend that you use the default settings on your Axis device. ![]() Make sure the network infrastructure is well-managed QoS, enough bandwidth, and with well-planned network hops.Įstimate the bandwidth for an Axis device by using AXIS Site Designer. The computer’s setup such as CPU, GPU, memory card and other parts involving graphic processing also have a big impact on image fluency.Ī lagging, jerky, or choppy video streams due to high latency. Poor hardware and software from the client side can also be a factor. To reduce the bitrate, the device lowers the image quality or the frame rate.Ĭlient factors that can affect latency are media player rendering the video (unpack, reorder and decode), buffers, display refresh rate, and decompression. If the network bandwidth is limited, the device must compensate the quality of the stream (reduce the bitrate) to match the available bandwidth. Network factors that can affect latency are network infrastructure, amount of data, and transmission protocol (UDP/TCP). ![]() End-to-end latency is divided into three steps that impact the total latency device, network, and client latency.ĭevice factors that can affect latency are, for example, stream settings (resolution, image settings, audio, compression), capture frequency (sensor), multiple streams, and image processing. End-to-end latency is the delay from when an image is captured by a device until the image is visible on a video display. Lag is another term for delay, and it is caused by high latency. Typically, these settings are adjusted on the video management software side. This way, the camera doesn’t have to encode multiple streams simultaneously. If all the settings like resolution, format, frame rate, compression, and Zipstream are identical, the camera can encode just one stream for all clients instead of encoding a separate stream for each one. Video clients that request video streams from the same camera should request video streams using the same settings, if possible. If multiple streams are requested from a device, make sure that they all use the exact same settings. Limit the number of unique streams requested from the device simultaneously. Limit the number of streams and retry after a short period. The error message “Too many viewers” means that a multitude of unique streams has been requested simultaneously. A unit restart can be a temporary reason, but there could also be more severe firmware problems or errors in the configurations. ![]() The most frequent cause is an excessive number of streams. This error message indicates that the RTSP service is unavailable, but the root cause is unknown.
