Optex SL-350QN SmartLine Standard Outdoor Photoelectric Quad-Beam Detector, 350' Range

Built to protect perimeters where reliability matters most, the Optex SL-350QN SmartLine photoelectric quad-beam detector delivers robust outdoor security and intrusion detection for commercial sites. This Optex photoelectric beam detector provides a long 350' (100 m) detection range and a four-channel quad-beam configuration that reduces nuisance alarms and increases detection accuracy for perimeter, driveway, roof, and garden monitoring. Installers benefit from rapid optical alignment using the Sniper Viewfinder and high-visibility yellow chassis, shortening setup time and lowering commissioning costs. The IP65-rated, UV-resistant polycarbonate housing with anti-frost hoods keeps beams clear and stable in adverse weather, while wired connectivity and compatibility with the PIE-1 IP/PoE module enable easy integration into IP networks and modern surveillance systems. Low current draw and versatile pole or wall mounting make the SL-350QN a practical, low-maintenance choice for long-term perimeter protection. Ideal for security integrators and facility managers looking to strengthen perimeter surveillance—contact us to add the SL-350QN to your next intrusion detection or monitoring project.
