OPTEX VXI vs VXS Series: Choosing the Right Outdoor Sensor for Your Security Needs

When it comes to reliable outdoor intrusion detection, OPTEX VX sensors are a popular choice among security professionals. But if you're considering this solution, you may be wondering which model best fits your needs: the VXI (Infinity Series) or the VXS (Shield Series)?

Both the Infinity and Shield series deliver high-performance outdoor motion detection, yet they differ in design, installation features, and user experience. In this article, we’ll compare the OPTEX VXI vs VXS Series in detail to help you make an informed decision.

Key Differences Between the VXI and VXS Series

While both series offer similar performance and sensor technology, they differ in several critical aspects:

1. Design Concept

• VXI Series: Engineered for discreet placement, the Infinity series is designed to blend seamlessly into its surroundings.
• VXS Series: Created to enhance the look of the installation area, the Shield series features bold faceplates and multiple colour options, ideal for visible outdoor applications.

2. Ease of Installation

• VXI Series: Installation requires manual screw attachment of covers.
• VXS Series: Designed with blue touch elements for quick, tool-less fitting via a simple 90-degree turn. The integrated spirit level in the back cover ensures precise alignment, speeding up installation.

3. Walk Test Mode

• VXS Series: Comes with an automatic walk test mode that activates for three minutes once the front cover is closed.
• VXI Series: The walk test LED must be manually activated by setting a dip switch—more time-consuming for installers.

4. Back Tamper Feature

• VXI Series: The back tamper is optional, which may require additional setup.
• VXS Series: The back tamper is standard, providing out-of-the-box security against unauthorized sensor removal.

Final Thoughts

Whether you're securing a residential property, commercial perimeter, or high-risk site, both the Infinity and Shield series of OPTEX VX sensors provide cutting-edge outdoor protection. The VXI Series is ideal if you prefer a more subtle appearance, while the VXS Series is the top choice for easy installation and design-driven projects.
