Hikvision DS-2DY9250X-A 2MP 50× Network Positioning
System adopts 1/2.8" progressive scan CMOS chip. With
the 50× optical zoom lens, the camera offers more details
over expansive areas.
This series of cameras can be widely used for wide
ranges of high-definition, such as the rivers, forests,
roads, railways, airports, ports, squares, parks, scenic
spots, stations and large venues, etc.
