1. PT unit Integration – Focus
	A. Continuous Auto focus mode: RS485 only
		- When requesting the Pan/tilt/zoom, Camera switches to continuous auto focus mode.
		- On continuous Auto focus mode, Camera sends out Pelco-D command 0x2B with Auto Focus Ctrl setting set to 0
	B. Manual mode: Switch between ABF and RS485
		- When Camera is reqestued to near/far/push AF, switched the focus manual mode automatically. 
		- On focus manual mode, Camera sends out Pelco-D command 0x2B with Auto Focus Ctrl setting set to 1. 
		- There is a check box named Enable ABF on the webpage, which is using on focus manual mode.
		- If check box is checked, requesting focus near/far command is controlling ABF on camera. 
		- If not, requesting focus near/far commands will be sent via Pelco-D command to control the external zoom lens. Pelco-D command is followed by Pelco-D standard section 3.1.
