Integrated cameras are widely used in government projects, high-end skyscrapers, shopping malls, schools, hotels, and hotel lobbies. They are also ideal for environments with strict requirements, such as hospital operating rooms, where dust-proof, low-temperature, and non-sparking explosion-proof features are essential. Over the years, integrated cameras have broken the dominance of foreign brands like Sony, Hitachi, Samsung, Panasonic, LG, and CNB. As their prices continue to drop, they have attracted significant attention from industry players. Companies such as Zhejiang Dahua, Aipu Vision, Wanjiaan, Onix, and Digital China have now mastered the core technology of high-definition integrated cameras.
With the advancement of IP high-definition technology, the unique advantages of integrated cameras—superior to traditional models—have made them a new favorite in surveillance systems. Tiandi Weiye Wang Liang believes that although the high-definition integrated camera industry is still relatively small and prices remain high, the trend toward high-definition night vision and intelligent analysis features is growing. Features such as multi-line alarms and motion detection will become more common. Therefore, networking, high-definition, and intelligence are key directions for future development. From a cost-effectiveness and practicality perspective, integrated cameras are gradually replacing traditional models and becoming the preferred choice in monitoring systems. The market balance is shifting, and the share of integrated cameras is expected to grow significantly in the coming years, with broader applications.
Currently, HD network cameras in security monitoring mainly include bullet cameras, integrated cameras, dome cameras, and high-speed dome cameras. According to survey data, high-definition integrated cameras are not yet widely popular due to ongoing R&D challenges. Bullet cameras, on the other hand, have dominated the low-end market with their mature technology and cost-effectiveness. However, despite their popularity, many drawbacks remain unignored.
One major issue is **focus offset**. Bullet cameras consist of a body and lens, and their performance depends heavily on the compatibility between the two. If the user or installer lacks expertise, improper matching can lead to poor image quality. Manual focusing is often used, but it relies on visual inspection and manual adjustment, which is inefficient and inaccurate. Additionally, bullet cameras are sensitive to environmental factors like moisture, vibration, and thermal expansion, leading to issues such as blurred images, instability, and focus drift over time.
Another challenge is the **back focus adjustment problem**. Due to differences in sensor surfaces and lenses, back focus adjustment is critical for fixed bullet cameras. Traditional methods involve a back focus ring and lock screw, which can wear out over time, reducing stability. Some use plastic-based self-locking mechanisms, which may fail in extreme temperatures. Newer designs use threaded focusing systems, but these increase manufacturing costs.
The issue of **night vision** remains a concern. While manufacturers employ technologies like day/night infrared cut-off switches, color-to-black switching, 3D noise reduction, and wide dynamic range enhancement, the image quality at night still falls short of daytime clarity. Adequate lighting—whether white light, infrared, or laser—is necessary for clear night vision. The lens also plays a crucial role in low-light performance, especially for high-resolution cameras, which require specialized lenses.
**Zoom problems** also persist. Most bullet lenses are manual zoom with fixed focal lengths, making them suitable only for limited areas. Electric zoom lenses are available but are expensive and complex. These are typically used in specialized settings like border defense or forest monitoring, where high precision is required. Ordinary users find them impractical due to cost and complexity.
Due to these shortcomings, integrated cameras have gained more attention. Compared to bullet cameras, they offer variable zoom and auto-focus capabilities, making them ideal for long, narrow corridors where clear local details are needed. Unlike bullet cameras, which require on-site lens installation and adjustment, integrated cameras are easy to install and do not need complex setup. Their compact size makes them suitable for various locations, and network integration allows power, video, and control through a single cable.
Auto-focus technology ensures the image remains sharp at all times by adjusting the lens motor based on the subject's position. This eliminates the need for manual refocusing and improves overall efficiency. Integrated cameras also feature day/night conversion, dual filter switching, and excellent low-light performance. They offer wide dynamic range, digital noise reduction, and stable operation under varying conditions.
In addition, integrated cameras support functions like SD card storage, motion detection, PoE power supply, and Wi-Fi connectivity, enabling true "all-in-one" functionality. Compared to dome cameras, they provide better cost-performance and are easier to install, with simpler wiring and direct connections. Many models also come with waterproof features, making them suitable for outdoor use and extending their lifespan.
Overall, integrated cameras are increasingly seen as a superior alternative to traditional bullet and dome cameras. Their convenience, performance, and adaptability make them ideal for a wide range of surveillance applications. As technology continues to evolve, their market share is expected to grow further.
