Alarm.com ADC-V821 - Outdoor 720P POE Mini Dome Camera with Night Vision Reviews
Submitted on 01/02/2020 Alarm Grid
The Alarm.com ADC-V821 is an outdoor 720p mini dome camera for use with the Alarm.com platform. The camera is largely outclassed in every possible aspect by the ADC-VC826, and we will almost always recommend purchasing that camera over the ADC-V821. If you have an existing ADC-V821 Camera, then it will still work just fine. But you should be aware that there are newer, more advanced camera options available. While the ADC-V821 is a very good camera, it is not one we would recommend, simply because the ADC-VC826 is better across the board. For that reason, we give the ADC-V821 a 4-Star rating.
There are positive aspects to the ADC-V821. The camera features a small and compact design. In fact, it is slightly smaller than the ADC-VC826, which is the one advantage the ADC-V821 has over that camera. The ADC-V821 can utilize Power over Ethernet (PoE), which makes it easy to provide power to the device. If you do not want to use PoE, then you can use the camera's included 8-foot power adapter. However, you will still need to connect an ethernet cable to the camera anyway for network connectivity. Remember, you can always add a PoE injector if your IP router does not support PoE. One other aspect we like about the ADC-V821 is its weather-resistant design. The camera features an IP66 waterproof rating to keep out rain and moisture.
The negatives to the ADC-V821 are extremely pronounced when you compare it with the ADC-VC826. The ADC-V821 has 720p recording capabilities, which pale in comparison to the 1080p recording capability of the ADC-VC826. The ADC-V821 cannot connect to a WIFI network, meaning you must use ethernet with the camera. This is fine if you wanted to take advantage of PoE anyway, but having WIFI would have been a nice touch. The ADC-VC826 has much better night vision than the ADC-V821, which is another mark against this camera. And perhaps most remarkable is that the ADC-V821 costs MORE than the more advanced and more powerful ADC-VC826. There is almost no reason to pick the ADC-V821 over the ADC-VC826.
The ADC-V821 is a good camera, but it is outclassed by the ADC-VC826 in almost every category, including price. If you already have an ADC-V821, then we aren't saying to go out of your way to replace it. But if you are in the market for a new camera, we strongly recommend checking out the ADC-VC826 first. As for the ADC-V821, we give it 4 Stars.
Good: Small & Compact Design, PoE, Optional Power Adapter, IP66 Waterproof for Outdoor Use
Bad: 720p Recording, No WIFI Connectivity, Weak IR Night Vision, More Expensive than ADC-VC826
Bottom Line: 4 Stars
