In the era of high-definition explosion-proof cameras, both manufacturers and engineers are increasingly focusing on high-resolution surveillance. However, pursuing higher pixel counts isn't always the best approach. Instead, practicality and suitability should be the main considerations when choosing high-definition solutions. As Huang Gong, a senior technical engineer at Shenzhen Shiguo Science and Technology, explains, "Only the right ones are chosen, not the more expensive ones." The goal is to use the most appropriate pixel count for each specific application.
Currently, 1080P and 720P resolutions are the most popular in the market for explosion-proof high-definition cameras. These two formats can serve as a basis for comparison. In the security industry, there's no universal standard for what constitutes high-definition video. From a broadcast perspective, 720P follows the D4 standard with a resolution of 1280×720, while 1080P aligns with the D5 standard at 1920×1080. Both use progressive scanning, which eliminates flicker and delivers clearer, more stable images. While the human eye perceives optimal clarity at around 75 frames per second, 30 fps is generally sufficient for most explosion-proof camera applications.
From a market standpoint, 720P and 1080P cater to different audiences. 1080P requires larger screens (23 inches or more), powerful CPUs, and hardware decoding capabilities, making it suitable for high-end consumers. On the other hand, 720P targets the broader consumer base and offers a more cost-effective solution. The price difference between the two is significant, mainly due to the higher technical demands of 1080P.
In the field of explosion-proof camera surveillance, the ultimate goal is clear visibility. High-definition doesn't mean higher pixels are always better. Many people mistakenly believe that higher resolution automatically means better performance, but this overlooks the unique requirements of explosion-proof monitoring. The influence of consumer electronics has pushed the security industry toward high-definition, leading to a tendency toward over-specification.
Although 720P is gradually being phased out in broadcasting, it still holds a strong position in the security sector. According to Huang Gong from Shenzhen World Technology, the 720P era in explosion-proof camera surveillance is just beginning. With the rise of HD surveillance, 720P is expected to become the mainstream standard for future explosion-proof cameras. It may compete with 1080P, but the relationship is more complementary than competitive, largely due to cost and transmission/storage constraints.
High-definition surveillance is undeniably a growing trend, and it will play a major role in the market in the coming years. However, the cost of chasing higher resolutions also increases. Therefore, both manufacturers and engineers must make rational choices based on practical needs. As technology advances, the number of pixels in explosion-proof cameras could keep increasing, but the human eye's ability to perceive detail remains limited. Ultimately, the key is to capture useful information on a screen without unnecessary complexity. As Huang Gong puts it, "The choice of high-definition is only right, not the highest."
