â—‡ Network performance remains a critical challenge. The key advantage of network cameras lies in their ability to enable flexible remote monitoring, which has significantly expanded the application scope of video surveillance and enhanced the role of video in remote management and data sharing. However, despite these benefits, several shortcomings are evident. According to the survey, users frequently report issues such as coding efficiency, bandwidth limitations, system compatibility, stability, network latency, and night-time performance. As high-definition (HD) technology improves image quality, it also places higher demands on the bandwidth infrastructure. This has led manufacturers to focus more on developing IP-based systems with high-definition video at low bitrates.
â—‡ End-user requirements drive development. To better understand what contractors prioritize when purchasing and using network cameras, the survey focused on factors like image clarity, night vision, intelligent features, transmission speed, system stability, and ease of use. The results showed that image quality, reliability, compatibility, and network performance were the most important aspects for project teams. Notably, 83.33% of respondents rated image quality as a top priority.
â—‡ Image quality is the top concern. The quality of an IP camera (IPC) largely depends on its resolution. The survey found that 720P and 1080P models are the most popular among engineering firms. While 1080P has seen a significant increase compared to previous years, cameras with over 3 million pixels are less commonly purchased due to the increased bandwidth demand. Most companies find that 1080P provides sufficient image quality for most applications. Compared to traditional CIF-resolution cameras, 1MP HD IPCs offer better display clarity and smoother motion. HD supports both large-screen and 16:9 wide-screen displays, enhancing user experience. Additionally, HD cameras can support up to 60 frames per second, doubling the smoothness of standard definition.
â—‡ Compatibility plays a crucial role in system integration. As surveillance systems transition from closed to networked environments, open standards become essential for device interoperability. In the internet age, adopting open standards allows security vendors to provide scalable and flexible solutions, helping them compete globally. According to Huang Weiyi from Zhejiang Dahua Technology, the rapid growth of the IPC market is driven by increasing demand for HD imaging, improved domestic network infrastructure, and the adoption of standards like ONVIF and GB28181.
â—‡ Day and night performance needs improvement. With the growing use of surveillance in high-end private areas, cameras must perform well in low-light conditions. Low-light cameras have become highly sought after, and those equipped with infrared lighting are especially popular. These devices can function without external light sources. Some companies use advanced brightening technologies to enhance image quality in dim settings. Unlike regular cameras that switch to black and white in low light, these models maintain color accuracy, offering clearer images with reduced noise and no trailing effects. Improving low-light performance will help accelerate the adoption of HD network cameras.
◇ Ease of use is often overlooked. Despite their advanced features, network cameras are more complex than traditional analog systems, both in installation and maintenance. Survey feedback indicated that many engineers and users are not fully proficient in using network cameras. Therefore, manufacturers must design user-friendly interfaces, including PoE power supply, local video output, wireless support, and easy debugging tools. Hikvision’s Cheng Hao highlighted the importance of the ABF (Automatic Back Focus) function, which allows remote fine-tuning of focus through IE or client software, making installation and commissioning much simpler.
