The Arlo Pro 4 has great video quality, thanks to a 1440p (2K) video resolution, which is better than the 1080p on most other security cameras. Videos were clear with a lot of detail, making it easy to identify objects, animals, and people in the frame.
One of the Arlo Pro 4's best features is its night vision in colour and infrared modes. The colour night vision uses a built-in spotlight to light up subjects near the camera when there's motion. It's useful for getting a little more detail, but it's not as discreet as the infrared night vision setting.
We noticed a delay between an action and when it shows up during a live video stream. The delay depended entirely on our internet bandwidth, so you shouldn't have problems with a speedy internet connection.

We appreciate the Arlo Pro 4's 160º field of view, which is much wider than a typical security camera (around 130º on average). Such a broad perspective outdoors means less cameras needed for an area like a backyard—saving you money and hassle.
Although the field of view is great for capturing a lot of detail, you can adjust it in the app to 125º or 110º—both of which can work well for recording video indoors.
There's also an option to automatically zoom and track people moving in front of the Arlo Pro 4, which is more helpful outdoors when subjects are farther from the camera. We prefer to turn this setting off indoors because it can be jarring with closer objects.

You can adjust the brightness of the video for different situations. While the camera's night vision performed best with maximum brightness, a lower setting during the day helps avoid washing out the video's color.
Unfortunately, the brightness doesn't automatically adjust as needed, so we recommend choosing a medium brightness so you don't need to change settings often.
To record video with the Arlo Pro 4, you can switch between five settings:
- Disarmed turns off all recording, but you can still record videos when viewing a live stream.
- Armed allows the camera to record video whenever there's motion.
- Schedule records video only during specific times.
- Geofencing activates other recording modes based on your location.
- Custom mode allows you to adjust when the camera records.
