How to Stop Hikvision (Hik-Connect) Camera Polling/Refresh46

Hikvision, a leading manufacturer of surveillance equipment, uses a polling mechanism in its software (like Hik-Connect, iVMS-4200, and others) to regularly update the live feed and status of connected cameras. While this ensures a near real-time view, excessive polling can sometimes lead to performance issues, particularly on networks with high latency or limited bandwidth. This article delves into understanding Hikvision's polling mechanism and explores several methods to manage or reduce its frequency, ultimately optimizing your surveillance system's performance.

Understanding Hikvision's Polling Mechanism

Hikvision's client software, whether it's the mobile app Hik-Connect or the desktop application iVMS-4200, employs a continuous polling strategy. This means the software regularly sends requests to the cameras to retrieve updated images and status information. The frequency of this polling varies depending on several factors: the software version, network conditions, camera settings, and the number of cameras being monitored. A higher polling rate provides smoother video, but consumes more bandwidth and processing power.

Why You Might Want to Reduce Polling

Several scenarios might necessitate reducing Hikvision's polling frequency:
Network Congestion: In networks with limited bandwidth, excessive polling can lead to noticeable lag, impacting other network activities.
High Latency: High latency networks (e.g., long-distance connections, satellite internet) can amplify the impact of frequent polling, resulting in delayed video and sluggish software response.
Resource Constraints: Older computers or mobile devices with limited processing power might struggle to handle the constant data stream from numerous cameras.
Power Consumption (on cameras): While less significant, continuous polling can contribute to slightly higher power consumption on the cameras themselves.
Improved Battery Life (on wireless cameras): For wireless cameras, reducing polling can significantly extend their battery life.

Methods to Manage Hikvision Polling

Unfortunately, there's no single "stop polling" button within Hikvision software. However, several strategies can effectively manage and reduce the polling frequency:

1. Adjust Refresh Rate (if available): Some Hikvision software versions offer a setting to adjust the refresh rate for live video. Look for options like "Refresh Rate," "Polling Interval," or similar settings within the camera or system settings. Reducing this value will lower the polling frequency. Note that this is not always readily available depending on the software and camera model.

2. Optimize Network Conditions: Addressing underlying network issues is crucial. This might involve:
Upgrade your internet connection: Consider a faster internet connection with higher bandwidth.
Improve Wi-Fi signal strength: Ensure strong and stable Wi-Fi for wireless cameras.
Reduce network traffic: Identify and limit other applications consuming significant bandwidth.
Network segmentation: Segment your network to isolate your surveillance system.

3. Reduce the Number of Simultaneously Viewed Cameras: Viewing fewer cameras simultaneously significantly reduces the overall polling load on the network and software. Instead of viewing all cameras at once, focus on specific areas or cameras when needed.

4. Software Optimization: Ensure you're using the latest version of your Hikvision software. Updates often include performance improvements and bug fixes that can improve polling efficiency.

5. Camera Settings (Advanced): Some advanced camera settings might indirectly influence polling behavior. Consult your camera's manual for options related to frame rate, bitrate, and encoding. Lowering these settings can reduce the data volume transmitted, thus reducing the impact of polling.

6. Use a NVR/DVR (Network Video Recorder/Digital Video Recorder): Using a dedicated NVR or DVR to manage your cameras allows for local recording and reduces reliance on constant client-side polling for live viewing. This is often the most efficient solution for large-scale surveillance systems.

7. Consider Third-Party Software: Some third-party surveillance software might offer more granular control over polling frequency or utilize more efficient streaming protocols. However, be cautious when choosing third-party software and ensure compatibility with your Hikvision cameras.

Troubleshooting Tips

If you're still experiencing performance issues after trying these methods, consider these troubleshooting steps:
Check your camera logs: Look for any error messages or unusual activity within the camera's logs.
Restart your cameras and software: A simple restart can often resolve temporary glitches.
Contact Hikvision support: If the problem persists, contact Hikvision support for assistance. They can help diagnose specific issues and provide tailored solutions.

By understanding Hikvision's polling mechanism and implementing these strategies, you can effectively manage and reduce the frequency of polling, leading to a more efficient and stable surveillance system. Remember that the optimal approach depends on your specific network environment and system requirements.
