Resolution and Connectivity Comparison
Video Resolution
The ARENTI A4 Set delivers 2.5K resolution, which the manufacturer describes as 4MP HD clarity. This higher pixel count allows for sharper images and finer detail when you zoom in on your baby. In contrast, the ARENTI B2 Set offers standard 1080p resolution. While 1080p is clear enough for most nursery monitoring needs, the A4’s 2.5K spec provides better image density. If you prioritize seeing subtle movements or facial expressions with maximum clarity, the higher resolution of the A4 Set is the technical advantage. The B2 Set remains a solid choice if standard high-definition video is sufficient for your setup.
Wi-Fi Connectivity
Connectivity options differ significantly between these two models. The ARENTI A4 Set supports dual-band Wi-Fi, connecting via both 2.4GHz and 5GHz frequencies. This dual-band capability can help maintain a stable connection in environments with network congestion. The ARENTI B2 Set relies on 2.4GHz Wi-Fi for its app connection. Both units also feature a non-WiFi mode using 2.4GHz FHSS for direct communication with the parent unit, ensuring monitoring continues if the internet goes down. For users with busy home networks, the 5GHz support on the A4 Set offers a potential stability edge.
Night Vision Features
Both monitors include infrared night vision for low-light conditions. The ARENTI A4 Set enhances this with a multi-color RGB night light feature. You can choose from fixed colors, a breathing light mode, or a rainbow gradient to soothe your baby in the dark. The ARENTI B2 Set focuses on crisp infrared night vision but does not list any colored night light functionality. If you want to use the monitor to provide ambient lighting or a calming visual effect for your infant, the A4 Set’s RGB feature adds value. The B2 Set sticks to pure monitoring functionality.
Storage Options
Recording capabilities vary in their approach. The ARENTI A4 Set supports both local and cloud storage. You can insert a microSD card, up to 256GB, for local continuous or motion-activated recording. It also offers secure cloud storage for 24/7 recording. The ARENTI B2 Set provides free event recording with a 7-day loop stored on Amazon’s AWS using end-to-end encryption. It does not mention a microSD slot for local storage. If you prefer physical, local control over your footage without relying on cloud subscriptions, the A4 Set’s SD card slot is the practical advantage.
Physical Dimensions
The physical size of the camera units differs slightly. The ARENTI B2 Set measures 2.87 inches in width and 2.99 inches in length, with a height of 4.61 inches. The ARENTI A4 Set is slightly narrower at 2.48 inches wide and shorter in length at 2.76 inches, though it is slightly taller at 4.72 inches. The B2 Set weighs 1.25 pounds, while the A4 Set weighs 1.45 pounds. These differences are minor and unlikely to affect placement options in most nurseries. Both designs are compact enough for standard shelf or wall mounting without significant spatial concerns.

You can connect via dual-band 2.4GHz and 5GHz Wi-Fi for stable remote viewing on your phone, ensuring clear video quality from a distance.
