Hi. Your link does not show a tracking ptz 
 
	 
 
	however it does have motion detection which is useless on a ptz just like a ptz with a microphone 
 
	motion detection will only work if your ptz stays static then it will do motion but if you put presets into the ptz ....... every time the camera moves you will get a useless alarm
 
	 
 
	ptz audio ........ built in microphone on a standard fixed camera is good 
 
	on a ptz all your going to hear is two motors as ptz moves also making audio useless unless it stays static ...... so you may as well just buy 2 ptz cameras with the right size lens
 
	 
 
	anything that uses the HIsee app is junk just like the app ..... and it does not work on new iPhones
