Selling points:
1. Fastest focus speed in china market -using real digital focus, we are the first factory making the fast focus Speed for zoom camera in china market, its focus speed is only one second, and priciser.
2. RS 485. The new zoom camera with RS485. So you can connect with Keyboard orDVR directly, no need to connect with decoder anymore.

3. Power on memory position function. To be easily understanding I would like to take one sample. Eg, the camera is on 5x zoom position under the power on situation. But now power off, when the power on again, the zoom camera will start on 5X zoom only. So we call it is power on memory position function.
