Although the growth of the global economy is slow, the ever-widening gap between the rich and the poor, especially after the September 11th incident in the United States, has undergone major changes in the international and domestic security environment, and social unrest factors and suspected crimes have rapidly risen. People's attention to safety precautions has led to the rapid development of the global security equipment market. Today, the United States will be the world's largest market for security equipment.
Due to market demand and technological advances, surveillance cameras have entered the era of high-definition. In the past, surveillance market generally believed that the resolution of interlaced images of 4CIF (704X576) or D1 (720X480) could be called high definition, while the field of broadcasting and video teleconference put interlaced images of D3 (1920X1080), ie 1080i or D4 (1280X720). ) Line-by-line scan of the image, ie 720P can be called HD. High-definition cameras have higher requirements for lenses, CCDs, DSP chips, and even pan/tilt, etc. As the surveillance market increases the demand for high-definition cameras, its price will drop rapidly.
At present, the domestic manufacturers of high-end camera products have not had much difference with foreign manufacturers in terms of time. Sony, Samsung Electronics and other foreign manufacturers have launched 2 million, 3 million-pixel HD cameras for surveillance soon. Domestic Hakka and Dali also Launched a 2-megapixel network camera. The key to the intelligentization of the surveillance system lies in the intelligentization of the front-end camera equipment. It is of great significance for improving the system's response speed, reducing the occupied bandwidth of the transmission, and reducing the storage capacity. Some domestic and foreign security companies have already launched cameras with embedded video analysis function modules. Its market prospects are relatively good.

Optimum preparation quality
The grinding mode is available on the AccuTOM-100 and can be used for all types of materials (multiple two-way finishes are used between x-direction movements to ensure excellent flatness). Two grinding methods are provided for precise control of material removal to achieve optimum preparation results.
