Arlo Floodlight Camera

Design and Build Quality

Both the Arlo Pro 3 and Arlo Pro 4 cameras sport a sleek, weatherproof design suitable for indoor and outdoor use. They come with magnetic mounts, making installation a breeze, and can be positioned on walls or ceilings. The Pro 4 does have a slight edge when it comes to build quality, with improved weather resistance, making it even more durable in harsh conditions.

Video Quality

One of the critical aspects of any security camera is its video quality. The Arlo Pro 3 features a 2K resolution with High Dynamic Range (HDR), providing excellent clarity and color accuracy. However, the Pro 4 takes it up a notch with a 4K Ultra HD resolution, resulting in even sharper and more detailed footage. If high-resolution video is a top priority for you, the Arlo Pro 4 is the clear winner.

Night Vision

Both cameras offer impressive night vision capabilities, thanks to their infrared LEDs. However, the Arlo Pro 4 enhances this further by introducing color night vision, which provides a more detailed and vibrant image in low-light conditions. This can be a game-changer when it comes to identifying intruders or simply checking on your surroundings at night.

Field of View

The Arlo Pro 3 and Pro 4 come with a 160-degree field of view, which is wide enough to capture a significant area without the need for multiple cameras. This wide field of view ensures that you won’t miss any important events or details in your footage.

Audio Quality

Both cameras support two-way audio, allowing you to communicate with visitors or potential intruders through the Arlo app. The audio quality is clear on both devices, making it easy to have conversations with people on your property or even scare off unwelcome guests.

Battery Life

Battery life is a crucial consideration for wireless security cameras. The Arlo Pro 3 and Pro 4 come equipped with rechargeable batteries that can last for several months on a single charge, depending on usage. However, the Pro 4’s more efficient power management system may give it a slight edge in this department.


As is often the case with newer models, the Arlo Pro 4 is typically more expensive than the Pro 3 due to its upgraded features and capabilities. If budget constraints are a concern, the Pro 3 remains a solid choice with many advanced features at a more affordable price point.


In the battle of Arlo Pro 3 vs. Pro 4, both cameras offer exceptional security and smart features that can enhance the safety of your home. The choice ultimately boils down to your specific needs and budget. If you prioritize the latest technology and the sharpest video quality, the Arlo Pro 4 is the way to go. However, if you’re looking for a more cost-effective option that still provides excellent security and smart capabilities, the Arlo Pro 3 won’t disappoint.
