The 2GIG GC3PK-3G-A provides all of the equipment that an apartment, small home or small business needs to achieve a dependable security setup. The kit is centered around the 2GIG GC3 Control Panel, which is one of the most impressive wireless all-in-one (AIO) systems currently available.

The complete kit provides a new 2GIG GC3 System, 3 VERSA-2GIG Door and Window Contacts, a 2GIG PIR1-345 Motion Sensor, a 3G AT&T Cellular Communicator, and a Honeywell LT-Cable for providing power. By being able to monitor up to three different doors and windows, this kit can provide top-level protection for virtually any apartment, small home or small business. The included motion sensor should be installed in a large central location near the primary entryway so that it will detect the motion from an intruder. This provides an added layer of security for an already robust setup.

The 3G AT&T Cellular Communicator allows the system to connect with the AT&T 3G Cellular Network and the Alarm.com servers. Cellular communication is incredibly reliable, and it will help to ensure that the system remains connected to the network at all times. Cellular connectivity almost never goes down or becomes unavailable. It is also unaffected by electrical outages, and it will continue to keep the system connected when the power is down. And since the GC3 also comes WIFI-ready, this kit will immediately allow the system to achieve a dual-path communication setup. However, users should note that a cellular monitoring plan will be needed to activate the communicator.

Once the communicator has been installed and activated, the system will be able to access the Alarm.com interactive service. Alarm.com allows a user to arm and disarm their system, check the current status of sensors, control smart home devices, and view the live feed of security cameras. All of this can be done from the Alarm.com website or by using the Alarm.com Mobile App on any Android or iOS device. Alarm.com access also allows the panel to be used with the Google Home and Amazon Alexa assistants.

The 2GIG GC3 supports 345 MHz security sensors. These include wireless 2GIG Sensors and the Honeywell 5800 Series Sensors. It is very easy to enroll new sensors with the system, and a user will have no problem expanding upon their setup if they desire. The panel supports a wide range of security and life-safety devices, including smoke detectors, glass break sensors, flood sensors and more. Any device that is added will be visible both from the panel and from the Alarm.com platform.
