Features :
- This high-speed dome camera is specially designed for video tracking and high-definition video recording of conference systems. It has high-speed rotation, high-definition image quality, stable and reliable performance characteristics, and is widely used in various international conference occasions and hotel banquet video recording. 
- Man-machine dialog programming menu with built-in sphere system, camera, and pan/tilt function settings. (Operation help, information prompt) 
- The power-on self-test information prompts the remote menu to modify the protocol, address, baud rate and other communication information, and has a remote reset function. 
- DSP digital technology design, compact structure, stable operation, ultra-low noise, no jitter on the picture 
- Integrated high-definition color camera, universal variable speed pan/tilt and multi-function decoder 
- Color camera with horizontal resolution of 480 lines, clear and natural image 
- 18x optical zoom, 12x digital zoom, 216x total zoom 
- High-definition recording, auto iris and gain, auto focus, auto white balance, ultra low illumination in dimly lit environments 
- Menu programming: clock display, preset position, vertical/horizontal scanning, preset navigation, four-point scanning, multi-point scanning 
- 6 sets of programmable horizontal and vertical scanning speeds: the built-in menu setting allows scanning speeds between 1-255 degrees per second 
- 6 groups can be programmed with multi-point string and preset position running track mode 
- 6 sets of two-point scanning: programmable vertical, horizontal synchronous track spherical operation 
- 2 sets of pattern track running storage demonstration, can be remembered including standard P/T/Z control track 
- Auto flip: allows the ball to rotate 180 degrees horizontally from vertical stroke to bottom
