Slow live view speed on Hikvision recorders is a common problem faced by many users. Live view can have a delay, become choppy (robotic), or completely freeze the frame. This can be frustrating, especially if you rely on your recorder to manage and monitor the property.
There are several reasons why this problem might occur, such as inadequate bandwidth, insufficient output bandwidth limit, and network situations. In this article, we will provide a detailed solution to this issue, step by step.
It is important to understand that the bandwidth for output should be high enough for the device sending stream.
The output bandwidth is the amount of data that can be sent out of the recorder at any given time. If this bandwidth is too low, it can cause slow stream speed. Therefore, it is essential to ensure that the output bandwidth is sufficient to handle the stream.
My Camera Live View is Slow
For DVR (that uses HD coaxial cameras), it is necessary to check if the output bandwidth limit is too small to allow a multi-channel live view. To do this, go to Configuration > Network > More Settings > Output Bandwidth Limit.
Keep in mind that the Output Bandwidth Limit only takes effect on analog camera channels. If the limit is too small, it can cause slow live view speed, you need to adjust the limit to a higher value.
Next, you need to make clear in which network situation the slow live view speed occurs. Whether it is a 4G/5G or WiFi network, it is crucial to pay attention to whether the issue occurs in a particular situation like a cross ISP network.
A poor network connection can cause slow live view speed, but you need to investigate first if the live view has a delay regardless of the connection type (WiFi, 5G, etc).
For the next step, check the single-screen live view speed (which means opening one camera only in the live view mode). If the live feed is still delayed, there are two options.
- Change the sub-stream resolution to a lower level, and decrease the frame rate, and bitrate. This will reduce the load on the network and improve the live view speed. For example, from 8MP or 4MP, drop it to 2MP. Save the settings and re-check the live view.
- Re-configure ports, device user name, and password. Depending on the DVR model, you may need port forwarding to function properly. Open up the Server, HTTP, and RTSP ports.
Additionally, you may check the stream speed when streaming in IP/Ports . Simply do a test of the upload and download speed.
Many Hikvision models display these speeds on the Network section. If the stream speed is still slow, it means that the recorder is not able to upload the feed through the internet.
Another thing to consider is the firmware version of the recorder. Make sure the unit is updated to the latest firmware version. Sometimes the outdated version contains bugs or other issues that are solved when the firmware is updated.
Actually, updating the unit is the first thing you need to do. Also, you need to make sure that the phone app (Hik-Connect) is updated as well.
If you still can make it work, collect your system’s information such as device model, firmware version, network configuration, device’s serial number, and region, and contact Hikvision USA or the seller/dealer for further technical support.
Sometimes Hikvision technicians may remotely access the system to perform troubleshooting. If so, you may need to provide the Hik-Connect account and password.
To conclude, slow or delayed live view on Hik-Connect can be caused by several factors such as inadequate bandwidth, insufficient output bandwidth limit, and network issues.
By following the above suggestions, you can fix it. As the last resort, you can contact your seller or supplier for technical help.
