In the era of high-definition explosion-proof cameras, both manufacturers and engineers are focusing on improving image resolution. However, pursuing higher pixel counts isn't always the best approach. Instead, the emphasis should be on practicality and suitability for specific applications. As Huang Gong, a senior technical engineer at Shenzhen Shiguo Science and Technology, puts it: "Only the right ones are chosen, not the more expensive ones." When selecting high-definition explosion-proof cameras, it's not about having the highest resolution possible, but rather choosing the most appropriate pixel count for each specific use case.
Currently, 1080P and 720P are the two most common resolutions in the market. While both are considered high-definition, they differ significantly in performance and application. From a broadcasting perspective, 720P aligns with the D4 standard, offering a resolution of 1280×720, while 1080P follows the D5 standard with a resolution of 1920×1080. Both use progressive scanning, which eliminates the flicker caused by interlaced scanning and provides clearer, more stable images. Although the human eye is most comfortable with 75 frames per second, 30 frames per second is sufficient for most surveillance applications.
From a market standpoint, 720P and 1080P serve different user groups. 1080P requires larger screens (23 inches or more), higher CPU power (over 3GHz), or hardware decoding graphics cards, making it more suitable for high-end consumers. In contrast, 720P targets a broader audience and is more cost-effective. The price difference between the two is significant due to the higher technical demands of 1080P. For explosion-proof camera systems used in security monitoring, clarity and usability are key. High-resolution alone doesn’t guarantee better results if the video isn’t clear enough for effective monitoring.
Despite the growing trend of high-definition in consumer electronics, the same logic doesn’t always apply to explosion-proof cameras. Many users mistakenly believe that higher pixels always mean better performance. However, in explosion-proof environments, factors like cost, transmission efficiency, and storage capacity also play a crucial role. According to Huang Gong, the 720P era is just beginning in the explosion-proof camera industry, and as HD surveillance becomes more widespread, 720P will likely become the mainstream standard. It may compete with 1080P, but more often, they will complement each other.
High-definition is undeniably the future of surveillance, but chasing higher resolutions comes with increased costs. Manufacturers and engineers must make rational choices based on real-world needs. As technology advances, the number of pixels in explosion-proof cameras may continue to grow, but the human eye has limits in terms of what it can perceive. Ultimately, the goal of surveillance is to provide useful information, not just high-resolution images. As Huang Gong wisely states: “The choice of high-definition cameras is only right, not the highest.â€
