Optex ABC-4 Anti-Bird Cap for SL Series

Protect your perimeter sensors and reduce nuisance alerts with the Optex ABC-4 anti-bird cap, a purpose-built enclosure accessory for SL-series detectors. This compact anti-bird cap prevents birds and small animals from perching on the detector while also shielding the detector’s front from excessive rain and snow — helping preserve sensitivity and consistent performance for security and surveillance systems. Specifically designed for compatibility with the Optex SL-350QFR (SL series) and offered in a low-profile black finish, the ABC-4 installs quickly as a retrofit or during new deployments. By minimizing environmental and wildlife triggers, it reduces false alarms and lowers maintenance time for monitoring teams, improving uptime for CCTV and alarm integrations. As part of Optex’s SmartLine offering, the ABC-4 is an economical way to extend the reliability of detection equipment in outdoor installations. Add the Optex ABC-4 to your detector mounting and enclosure plan to enhance accuracy and long-term performance—ideal for commercial, industrial, and critical infrastructure security applications.
