2MP/1080P 36x IMX291 Starvis Block Camera for IP PTZ Dome Camera
As the PTZ camera is able to provide 360 degree video surveillance coverage, they are the best cameras to monitor large open space areas. In addition to almost the endless mechanical pan/tilt rotation, each PTZ camera comes with a block camera that can not only deliver high quality video but also offering powerful optical zoom capability. For instance, the PTZ camera can support 10x, 18x, 20x, 30x, 36x even higher optical zoom. A 36x optical zoom dome camera therefore can see an object clearly which is a few kilometers away. If you just want to capture the object in a few hundred meters away, 18x and 20x optical zoom is quite adequate.
