Command and Instructions:1.The lens curve learning command: 253 + set + 252 +call
(The distance between the camera and the object must be greater than 50meters)
2.Minimum focus distance setting:Set command: 251 + set + X + call.
When X = 1, the minimum focusing distance is about 1.5 meters;
when X = 2, the minimum focusing distance is about 3 meters;
when X = 3, the minimum focusing distance is about 6 meters;
when X = 4, the focusing distance is infinity.Default X = 2
3. Focus mode setting:Set command: 250 + set + X + call.
When X = 1, the focus will only be triggered when the zoom movement is triggered;
when X = 2, any change in the pan, tilt, left, right, and zoom modes will trigger the movement to focus;
when X = 3, the automatic focusing mode, In any case, the movement will automatically focus. Default X = 2
4. Modification Digital ZOOM:
If ip address of camera is 192.168.188, Please open the browser and enter this address:
//192.168.1.88/cgi-bin/hi3510/param.cgi?cmd=setmaxezoom&-maxezoom=10
When maxezoom=1,digital zoom close,
Maxezoom value can be equal to any value from 1-10, representing the multiplier digital zoom of the number.
After the command is executed, please power off andrestart the camera. digital zoom to take effect
5.ZOOM OSD display and not display: 225 + call + X + call,
when X = 1, the ZOOM timesdisplay is on;
when X = 2, the zoom timesdisplay is off, the default X =1
6.Modify the control protocol method (you need to restart the movement to take effect after modification):
254+set+1+set: VISCA protocol (default) (PELCO-D, baud rate: 9600, address code: 1/255)
254+set+2+set: PTZ serial port protocol (PELCO-D, baud rate: 9600, address: 1
7. The movement supports the standard Visca protocol with a baud rate of 9600.
The address codes of the dome camera is 1
Humanoid recognition algorithm based on deep learning.Based on Huawei's deep learning humanoid recognition algorithm V2.0,
itprovides accurate humanoid recognition, providing continuous humanoid coordinates for the camera and smooth tracking of the camera.
