Side by side

Arlo 2-Sensor vs 5-Sensor System Compared: Two multifunction units cover fewer physical locations than five sensors do

Quick verdict

A small home is well served by the neat two-sensor kit. The five-sensor set reaches more doors, motion areas or spaces prone to leaks.

Before you buy

Why, and what it costs you

Where these two really part ways

Arlo Home Security System with 2 Sensors is the better match for “A setup compact enough for an apartment” and “Service on a month-to-month basis”. Arlo Home Security System with 5 Sensors is the better match for “Several doors and windows get a sensor” and “Wider coverage, suited to a larger house”.
