Before introducing Arlo Pro 3, Netgear released Arlo Ultra with 4K resolution, quadruple jump the resolution compared to the previous Arlo Pro series. However, this Arlo Ultra does not get a good customer rating compared with the previous Arlo Pro series. Maybe this is also the reason Arlo released Arlo Pro 3 with a resolution of 2k so that there is no resolution gap between the previous Arlo series of resolutions of 1k (Arlo Pro), 2k (this product) and 4k (Arlo Ultra).

Arlo Ultra vs Pro 3

If you notice the two camera models look the same, both are equipped with one high power spotlight LED to add lights at night so you can view and record footage in color instead of black and white like night vision camera in general.

What are the main differences between Arlo Pro 3 and Arlo Ultra which were released earlier than Arlo Pro 3? Surely the main difference is the image resolution for Arlo Pro 3 which is half of the Arlo Ultra’s image resolution. This will be a competing product for Amcrest acd2w wifi camera with spotlights.

Wide angle

Besides the resolution, there is a difference in the width of the viewing angle, Arlo Ultra provides a full 180 degree view angle forward, so that the left and right side of your frame looks curved because the lens used is like fish eye lens type when you’re familiar with photography.

Wifi connection

Arlo Pro 3 provides up to 4mp maximum resolution, so it does not require too much bandwidth compared to Arlo Ultra which gives twice the resolution as Pro 3. Of course, it requires a wider WiFi connection as well. Hence Arlo Ultra provides support for dual band wireless AC (802.11ac) for connection to the Arlo Ultra base station.

Arlo Pro 3 requires an Arlo Ultra base station connection. Arlo Ultra base station is based on wireless AC to allow connection to Arlo Ultra camera, but it can also connect to other Arlo 2k or Arlo Pro series.
