ADC-722W vs ADC-721W Alarm.com Camera Comparison

The ADC-722W and the ADC-721W are two outdoor HD cameras for use with the Alarm.com service. The 722W is typically considered to be an upgraded version over the 721W. However, both of these high-definition outdoor security cameras can make for a great addition to a video surveillance setup.

When comparing the two cameras, it's clear that the ADC-722W is equal or superior in every meaningful category. Both cameras are excellent for outdoor use, and they are identical in terms of outer casing and operating environment. They also both interface with the Alarm.com service, and they possess identical night vision capabilities.

However, the ADC-722W outshines the ADC-721W in terms of recording quality. The ADC-722W provides superior recording quality, a wider viewing angle and a more advanced camera lens. It also allows for faster network connectivity, since it can use a 5GHz WIFI connection, while the 721W can only use a 2.4GHz WIFI connection. However, there is one advantage that the 721W maintains over the 722W. That is the ability to use a hardwired ethernet connection if desired. Unfortunately, the ADC-721W has been discontinued, so it's likely that only used models are available.
