eufy Sensor vs Arlo Camera Specs
video resolution
Arlo offers 2K video resolution, which provides two times the detail of standard HD. This allows you to zoom in up to 12X to see sharper images. The eufy Security Entry Sensor does not capture video. It is a dedicated contact sensor designed to detect when a door or window opens. It relies on a magnetic switch rather than a lens. If you need visual evidence of who entered your home, the Arlo camera provides that data. The eufy unit only sends an alert when the contact is broken. It cannot show you what happened visually.
connectivity
Arlo supports dual-band Wi-Fi, connecting to both 2.4 GHz and 5 GHz networks. It automatically selects the stronger signal to maintain a stable connection. The eufy Security sensor requires a HomeBase to function. It does not connect directly to your Wi-Fi router. Instead, it communicates with the central hub, which then connects to your network. This means the eufy sensor depends on the HomeBase being powered and online. Arlo cameras connect directly to your internet infrastructure. This direct link can offer more reliable real-time notifications for the Arlo system.
power source
The eufy Security Entry Sensor runs on a single CR123A battery. The manufacturer states this battery lasts for 800 days, or roughly two years. This long lifespan reduces maintenance frequency significantly. Arlo Pro 5S cameras are wireless but typically use rechargeable batteries that require periodic charging or swapping. The data for Arlo does not specify battery life in days. The eufy sensor is designed for set-and-forget operation with minimal intervention. If you prefer not to check battery levels often, the eufy unit offers superior longevity.
night vision
Arlo cameras feature color night vision and an integrated spotlight. This allows you to see critical details in color even in low light. The spotlight also serves as a deterrent to unwelcome guests. The eufy Security Entry Sensor has no night vision capability. It does not have a camera or a light. It simply detects the physical separation of the magnet and sensor. If you need to see who is at your door in the dark, the Arlo camera is the only option that provides visual data at night.
form factor
The eufy Security sensor is compact, measuring 1.1 inches wide, 0.87 inches high, and 2.91 inches long. It weighs only 2.4 ounces. This small size allows it to fit discreetly on any door or window frame. Arlo cameras are larger, measuring 2 inches wide and 2.7 inches high. They are designed to be mounted in a visible position to deter crime. The eufy unit is less obtrusive. If you prefer a low-profile device that blends into your window trim, the eufy sensor is the better choice.
Choose the right system for 2026
You want video evidence of visitors
The Arlo Pro 5S captures 2K video, giving you twice the detail of standard HD. You can zoom in 12 times to identify faces clearly. The dual-band Wi-Fi ensures a stable connection on 2.4 or 5 GHz networks. Color night vision helps you see important details even in low light conditions.
You need simple door monitoring
The eufy Security Entry Sensor detects when doors or windows open. It runs on a single CR123A battery for up to 800 days. A 100-decibel siren sounds on the HomeBase when forced entry is detected. The compact design fits easily on any frame without complex wiring or setup.

This Arlo pack includes two wireless cameras designed for outdoor placement. The integrated spotlight deters unwanted guests at night. You get a seamless setup with included mounts.
