Million HD monitoring common five problems and solutions
Compared to traditional video surveillance, the HD surveillance system offers a significant advantage. The integration of monitoring with "networking" has become a game-changer, transforming the industry and enabling powerful capabilities in real-time monitoring. However, after over a year of market deployment and application across various sectors, several challenges inevitably arise:
1. **High-definition Transmission**
Standard definition images typically use 720P or 1080P resolutions. To achieve optimal image quality, a network bandwidth of 4M to 8M is required. When scaling up to hundreds of devices, the data traffic becomes massive. Video streams are real-time, continuously putting pressure on network switches and infrastructure. Proper network planning is essential to avoid bottlenecks.
2. **HD Storage**
With large data flows, centralizing storage at each node presents challenges in terms of bandwidth and storage capacity. This requires efficient management to ensure scalability and performance, especially for large-scale systems.
3. **HD Display**
Many manufacturers focus only on camera resolution but neglect high-definition display solutions at the control center. Most systems rely on PC screens, which cannot fully utilize high-definition visuals on large video walls, limiting the overall effectiveness of the system.
4. **HD Management**
Some manufacturers still follow traditional analog approaches, using off-the-shelf hardware and third-party algorithms. While they provide basic digitalization, they often lack the ability to manage underlying camera data effectively, leading to limited flexibility and performance.
5. **HD Imaging in Low Light**
While HD performs well in daylight, it struggles in low-light conditions. Most HD cameras use CMOS sensors, which have poor light sensitivity. Even high-resolution CCDs are less sensitive than standard low-light CCDs. Nighttime monitoring, when most security is needed, becomes problematic for HD systems.
Behind the enthusiasm for HD products, it's crucial to take a more balanced approach and address these five key issues. Many manufacturers focus only on pixel count, assuming higher resolution equals better performance, without considering real-world implementation challenges. Some even artificially upscale lower-resolution images, misleading users.
After extensive project experience, we've developed effective solutions that address these challenges and deliver satisfactory results for most users.
Regarding **transmission**, fiber optic technology continues to reduce costs, allowing high-speed LAN switches and Gigabit-to-desktop connectivity. With the rise of broadband and the "triple-play" services, home internet speeds now reach tens to hundreds of Mbps, making high-speed, cost-effective internet more accessible.
For **storage**, IPSAN-based solutions offer high stability but limited compatibility. NVR systems using X86 architecture provide better flexibility and compatibility. For smaller systems, mainstream servers can also handle storage needs efficiently.
In terms of **display**, while single-screen decoding via PC graphics cards works well, large-scale video walls require dedicated high-definition decoding boxes to maintain image quality and performance.
For **management**, choosing front-end devices with rich hardware interfaces (like alarms, SD cards, intercom, and USB) allows flexible system configurations. Software must support multiple access methods, SDKs, and third-party integrations for seamless operation.
Finally, **night vision** remains a critical challenge. Many manufacturers overlook night-time performance, relying on outdated infrared solutions. Our company has developed advanced night vision technologies, including laser-based infrared lighting, which delivers excellent results without compromising aesthetics or installation flexibility.
Addressing these issues requires collaboration between system integrators and manufacturers. While transmission and storage can be managed through proper design, display and management demand deeper software and hardware improvements. Laser infrared lighting, however, offers an easy, cost-effective solution that significantly enhances user satisfaction.
