In the early days of security technology, many people who worked in the field remember that the compression chips used in DVR cards were extremely powerful and generated a lot of heat. To manage this, manufacturers often added heat sinks or even small fans to help dissipate the heat, as overheating could cause the system to crash. This wasn't just an issue with DVRs — cameras also had similar thermal challenges.
One of the key advantages of choosing a million HD product is its ability to deliver clear images in low-light conditions. As digital HD has become a widely accepted trend in the industry, many companies have rushed to offer high-definition solutions. However, we've noticed that some providers are using the same compression chips found in DVRs within their cameras. While a DVR's large casing and internal fan can handle higher power consumption, the same chip placed inside a compact camera would struggle with heat dissipation, making stability questionable — especially during hot summer days when outdoor temperatures soar.
Infrared cameras are commonly used in security systems, and they already produce significant heat. The infrared lamps themselves can be even hotter. What’s more, current low-illuminance HD cameras in China often lack strong sensitivity to both visible and invisible light. To achieve effective infrared performance, it's common to increase the number of infrared LEDs or the current, which only adds to the heat problem.
Excessive power consumption and heat generation bring several disadvantages: they make the cameras unsuitable for direct sunlight in summer, cause instability in infrared models, require larger enclosures increasing costs, and are not ideal for high-speed domes with motors that generate more heat. Additionally, using fans for cooling reduces the lifespan and reliability of the system.
Another important feature of million HD products is the quality of the sensor and the underlying technology. By using low-power digital camera movements and advanced low-illuminance CMOS technology, these cameras produce less heat and offer greater long-term stability. They also use the lowest power infrared LED products and low-illumination technology available, optimizing infrared lamp angles to match lens coverage, reducing the need for multiple LEDs while still achieving excellent night vision.
To further reduce heat from the power supply, the power source is often moved externally, using the world’s lowest power POE technology. This minimizes overall power consumption and heat output, extending the product’s lifespan. The design also focuses on thermodynamics and heat conduction, ensuring optimal thermal management for the board and chip, allowing for smaller enclosures without compromising cooling efficiency.
Network performance is another critical factor in digital HD cameras. All network cameras experience some level of delay due to the process of converting light into digital signals, processing, compressing, transmitting, and decompressing. The length of this delay depends on the manufacturer’s compression algorithms, network software, and decoding capabilities. A strong R&D team can significantly reduce latency, improving overall system performance.
Long network delays can be problematic, especially when adjusting lenses or monitoring areas with many channels. If multiple high-delay cameras are used, the entire system’s stability may suffer. In fact, network delay reflects a manufacturer’s technical strength and the reliability of large-scale systems.
According to a review by "Security Engineering Business" in August 2010, Zhongshi Weiye’s HD cameras showed a delay of just 0.11 seconds under the same 720P resolution and network conditions, compared to other brands that reached up to 0.4 and 0.7 seconds. Independent tests by security experts have confirmed that Zhongshi Weiye’s million HD products have the smallest network latency, and many engineering companies have verified this at various trade shows.
A major highlight of choosing million HD is the comprehensive system integration support. Unlike the analog era, where there was a unified standard, early digital HD lacked a standardized front-end and back-end communication protocol. Therefore, HD manufacturers must provide a full range of products, including different types of cameras, such as bullet, hemisphere, IR, ultra-low illumination, wide dynamic range, and speed dome cameras, along with backend devices like HD decoders, hybrid DVRs, NVRs, and more.
Incomplete product lines limit scalability, especially for large projects that require a variety of cameras and accessories. It also highlights the R&D capability of manufacturers. Many so-called HD companies lack real technological expertise, simply assembling off-the-shelf components. When issues arise in the field, after-sales support becomes a challenge.
Lastly, product maturity and stability are essential. Million HD offers a complete range of products, including gun cameras, hemispheres, IR versions, high-speed balls, elevator-specific cameras, wide dynamic range, low-light, zoom, NVRs, storage units, management platforms, decoders, modules, system cards, POE switches, fiber optic transceivers, and more. These products cater to diverse customer needs across different industries, ensuring there's always a suitable solution for every application.
