What to do if monitoring is blurry? Popular topics and solutions on the Internet in the past 10 days
Recently, blurred surveillance images have become one of the hot topics on social platforms and technology forums. Many users reported that the image quality of monitoring equipment deteriorated and became blurry after being used for a period of time, which affected the security effect. This article will combine the hot content of the entire network in the past 10 days, analyze the common causes of blurred monitoring, and provide structured solutions.
1. Statistics on hot topics related to monitoring fuzzy in the past 10 days
| Topic keywords | Discussion platform | heat index |
|---|---|---|
| Surveillance camera blurry | Weibo, Zhihu | 85% |
| Monitoring at night is unclear | Douyin, Bilibili | 78% |
| Surveillance lens cleaning method | Xiaohongshu, Baidu Tieba | 65% |
| Wi-Fi signal affects picture quality | Technical forum (such as CSDN) | 72% |
2. Analysis of common causes of unclear monitoring
According to the discussion data of the entire network, the monitoring ambiguity problem mainly focuses on the following five categories of reasons:
| Cause classification | Proportion | Typical performance |
|---|---|---|
| Lens stains (dust, rain, etc.) | 42% | The picture is partially blurry or speckled |
| Focus failure | 28% | The overall focus is out of focus and cannot be adjusted manually. |
| Network transmission problem | 15% | Caton, mosaic |
| Equipment aging | 10% | Progressive image quality degradation |
| Insufficient ambient light | 5% | Poor effect at night |
3. Solutions and practical suggestions
1. Clean the lens
Use a microfiber cloth + lens cleaner and wipe in a spiral direction. Note: Avoid spraying directly with alcohol!
2. Check focus settings
Some models need to be recalibrated through the APP, for example:
- Hikvision: Go to "Device Settings" - "Image" - "Focus Fine Adjustment"
- Xiaomi camera: press and hold the reset button for 10 seconds to restore to default
3. Network optimization
| Question type | Solution |
|---|---|
| Wi-Fi signal is weak | Install a signal amplifier or switch to the 5GHz band |
| Insufficient bandwidth | Reduce resolution (such as 1080P → 720P) |
4. Hardware maintenance
If the equipment is used for more than 3 years, it is recommended to check:
- Is the CMOS sensor aging?
- Degree of attenuation of infrared fill light
4. TOP3 effective methods tested by netizens
Based on Zhihu’s highly praised answers and Douyin evaluation videos:
Summary
Monitoring fuzzy problems need to be dealt with based on specific causes. Regular maintenance can extend the life of the equipment. If the solution by yourself does not work, it is recommended to contact the manufacturer to inspect the optical components. With the development of AI noise reduction technology, the clarity of intelligent monitoring is expected to be further improved in the future.
