Hikvision is a leading manufacturer of security products, offering night vision cameras with different specifications and performance levels. Among them, 50-meter night vision and 30-meter night vision are two common specifications. This article explains their differences and features.
1. Difference in Night Vision Distance
1.1 50m Night Vision
Hikvision 50m night vision products provide a longer viewing distance and can effectively cover larger areas at night.
They are usually suitable for security scenarios that require longer night vision range, such as:
- Exterior areas of public buildings
- Large parking lots
- Construction sites
- Open outdoor areas
1.2 30m Night Vision
Compared with 50m night vision, 30m night vision has a shorter viewing distance and is more suitable for smaller areas, such as:
- Home entrances
- Small shops
- Offices
- Garages
- It can provide relatively clear night monitoring images and works well in specific short-range surveillance scenarios.
2. Comparison of Night Vision Performance
2.1 Light Sensitivity
50m night vision cameras are usually equipped with larger light-sensitive components, allowing them to better adapt to darker environments and provide brighter, clearer night images.
30m night vision cameras generally use smaller light-sensitive components. They can work well under moderate lighting conditions, but their performance may be limited in extremely dark environments.
2.2 Image Details
Because 50m night vision products are designed for longer viewing distances, they usually use lenses with longer focal lengths. This allows them to capture details from farther away more effectively.
In contrast, 30m night vision cameras usually have shorter focal lengths and are better suited for close-range monitoring, such as indoor office surveillance or entrance monitoring.
3. Applicable Scenarios
3.1 50m Night Vision
50m night vision is suitable for large-area monitoring, such as:
- Public areas
- Large parking lots
- Construction sites
- Building perimeters
- Outdoor security zones
- Its stronger viewing distance and light sensitivity can cover larger areas and provide better security protection at night.
3.2 30m Night Vision
30m night vision is suitable for smaller monitoring areas, such as:
- Homes
- Small stores
- Garages
- Office entrances
- Indoor corridors
- Within a shorter viewing distance, it can provide good night monitoring performance and meet general security needs.
Conclusion
There are clear differences between Hikvision 50m night vision and 30m night vision in terms of viewing distance and performance.
50m night vision is suitable for large-area surveillance and provides longer viewing distance and stronger light sensitivity. 30m night vision is more suitable for smaller areas and general security applications.
When choosing a night vision product, the actual monitoring environment and security requirements should be considered. Selecting the right night vision distance can help achieve better surveillance results.
