Time of arrival
Once you have chosen your home security services, it’s time to schedule the installation. Be sure to select a time that is most convenient for you—as the homeowner, you must be present for your ADT monitored security system installation. Time slots for installation tend to vary between 8–9 AM, 12–1 PM, and 5–6 PM, depending on your location. If the 2-hour window you’ve scheduled cannot be met, you will be notified in advance.
