Yes and no.
Alarm.com used to have the ADC-V620PT which was a wireless camera with pan/tilt functions. That camera is outdated and no longer available at retail.
Alarm.com does not have any PTZ capable cameras at this time, nor am I seeing anything upcoming that features PTZ.
Through residential Alarm.com accounts, only Alarm.com branded cameras can be used. More information on video through Alarm.com, including compatible camera models, can be found here.
However, through Alarm.com Commercial Service plans, if you have an Alarm.com CSVR and a 3rd party camera with PTZ, that can be used. There is no specific models listed that can/cant be used but there are specific requirements that must be met in order to use 3rd party cameras with a commercial plan.
