The 2GIG XCVR3-GC3 is a 900 MHz transceiver and 345 MHz receiver for the 2GIG GC3, GC3e, and Edge. The GC3 and GC3e are already equipped with 345 MHz receivers to speak with the 2GIG Wireless Sensors like door contacts and motion sensors. Please power down the panel before installing.

The module replaces the receiver inside a GC3 Alarm Panel. The XCVR3 adds the ability for the GC3 to communicate with 900 MHz devices like the 2GIG IMAGE2 image sensor. Without this module the panel is not capable of the required bi-directional signaling. The module connects with the circuit board on the back of the panel.

The 2GIG GC3 wireless alarm control panel must have firmware revision 3.0.1 or newer. If you have an existing GC3 panel on firmware 3.0.0 (original version) it can be flash upgraded via USB or OTA (over the air via Alarm.com). Reach out to your Alarm.com dealer for pricing on OTA update. Alarm Grid customers can email us at support@alarmgrid.com to request an OTA update.

The 2GIG XCVR3-GC3 also works with the 2GIG Edge so that the 2GIG IMAGE3 can enroll with the system. The 2GIG IMAGE3 is the only image sensor that works with the 2GIG Edge at this time. However, as of June 2021, the 2GIG Edge will only see the IMAGE3 as an ordinary motion sensor, and it will not transmit images to Alarm.com at this time. A fix for this issue is expected to be released sometime in the future. We do not have an ETA for the fix at this time. Adding this module to the 2GIG Edge will not affect the panel's ability to support 2GIG eSeries Encrypted Sensors

Good Image Sensor Transceiver Module

The 2GIG XCVR3-GC3 is a transceiver module that allows you to use the 2GIG IMAGE3 Image Sensor with a 2GIG GC3, 2GIG GC3e, or 2GIG Edge System. An image sensor is basically a motion sensor with a built-in camera. The camera will take one or more photos when movement is detected. This is good for confirming an intrusion or a fire. The 2GIG IMAGE3 in particular is known for providing high-quality images. In fact, it is a noticeable improvement over earlier image sensors. This makes the 2GIG XCVR3-GC3 module a good purchase and a nice addition to your GC3, GC3e, or Edge System. That is why we give it 5 Stars.

Using an image sensor can be a great alternative to using a more expensive video surveillance setup. The images provided from the 2GIG IMAGE3 that is used with the 2GIG XCVR-GC3 are high-quality, and you can use the image sensor to confirm any intrusions or fires. The 2GIG IMAGE3 takes four (4) photos when activated, and they are sent to Alarm.com. This way, you can view the images remotely from a web browser or from a smartphone with the Alarm.com Mobile App. You can even manually request a photo using the peek-in feature from Alarm.com. This is ideal for requesting a photo at any time.

There are some downsides to the 2GIG XCVR3-GC3. It is a physical module that needs to be installed inside the panel, which can be inconvenient for some users. Additionally, while you can use the XCVR3-GC3 with the 2GIG Edge, the Edge System will only see a paired IMAGE3 Image Sensor as a regular motion sensor, and it cannot send images to Alarm.com. 2GIG says that this is not intended behavior, and a fix is being worked on. Unfortunately though, as of June 2021, image sensors on the 2GIG Edge will not work as intended. But despite these flaws, the 2GIG XCVR3-GC3 does its job well. For that reason, it earns 5 Stars.

Good: Alternative to Video Cameras, High-Quality Images, Peek-In from Alarm.com

Bad: Must be Installed, Image Sensors Do Not Work as Intended On the 2GIG Edge (Fix is being implemented)

Bottom Line: 5 Stars
