Ubiquiti USL-ENTRY-US monitor for door/wind open/close status

Ubiquiti USL-ENTRY-US Door and Window Sensor

Overview

The Ubiquiti USL-ENTRY-US is a compact door and window sensor designed for integration with UniFi security deployments. This UniFi Sensor monitors entry point status in real time, providing binary open/close detection across residential, commercial, and multi-site installations. The sensor communicates directly with the UniFi Controller, enabling centralized monitoring and alerting without requiring separate management interfaces or third-party integrations.

Key Features

The USL-ENTRY-US delivers straightforward, reliable entry monitoring through the UniFi management ecosystem. Weighing just 0.200 lb, the door and window sensor installs unobtrusively on frame edges or strike plates. Native UniFi Controller integration means the device appears in the same dashboard as cameras, access points, and other security infrastructure, eliminating vendor fragmentation. The sensor belongs to Ubiquiti's Security Accessories product family and is manufactured to consistent quality standards.

Deployment Scenarios

Organizations use the USL-ENTRY-US to monitor high-value areas, restricted access zones, and emergency exits. In retail environments, sensors on stockroom and loading dock doors trigger alerts when unauthorized openings occur. Data centers and server rooms deploy sensors on cabinet doors and equipment access points. Multi-tenant office buildings install sensors on stairwell doors, mechanical closets, and roof hatches. Healthcare facilities monitor supply room access and sensitive patient areas. Campus deployments protect laboratory spaces, IT closets, and administrative offices across distributed locations.

Network Integration

The sensor integrates seamlessly with existing UniFi Controller installations running on cloud gateways, Dream Machines, or traditional UniFi OS installations. Events appear alongside video footage and access logs within the unified dashboard. Alerts can trigger automations, notifications, or conditional video recording based on entry status. The device requires standard WiFi connectivity and communicates via the UniFi management protocol—no additional network configuration is necessary beyond standard site commissioning procedures.

Installation Notes

Mount the USL-ENTRY-US on door frames or window sills using the included adhesive backing or mechanical fasteners. Ensure line-of-sight or near-line-of-sight positioning to the nearest UniFi access point for reliable wireless connectivity. The sensor can be paired and commissioned through the UniFi Controller interface during initial setup. Typical installation requires under five minutes per device. Verify WiFi signal strength at each intended mounting location before final placement to avoid future connectivity issues.

Karl Wilson, Infrastructure Engineer

"The Ubiquiti USL-ENTRY-US fits well into complete UniFi deployments where you're already managing cameras and networking through a single pane of glass. Unlike standalone door sensors that demand separate apps and alerts, the USL-ENTRY-US sits natively in your UniFi Controller, so integrators don't need to maintain parallel management tools. The MPN USL-ENTRY-US appears in product listings and inventory systems consistently, making procurement straightforward for multi-site rollouts. For organizations standardized on UniFi, this sensor eliminates the friction of third-party integrations."
