The Alfatron Electronics ALF-20X-SD-TC is a dual-camera auto tracking PTZ designed for AV integrators and production teams serving education, corporate, and house of worship environments. The primary 20X optical zoom camera pairs with a fixed panoramic lens to simultaneously cover presenter close-ups and wide room context, giving operators and auto tracking systems the coverage they need without a second PTZ unit or manual switching.

SDI output makes the ALF-20X-SD-TC a direct fit for production switchers and recording systems already built around broadcast-standard signal paths. Network streaming via RTSP, RTMP, ONVIF, and GB/T28181 adds flexibility for IP distribution, remote monitoring, and software-based production workflows. RS-232 and RS-485 control ports with VISCA, Pelco-D, and Pelco-P protocol support integrate cleanly into existing AMX, Crestron, and third-party control systems without additional conversion hardware.

With 255 programmable presets, wide pan and tilt range, and remote upgrade and reset capability over the network port, the ALF-20X-SD-TC is built for permanent installed environments where reliability and remote management reduce on-site service calls. The dual 3.5mm audio inputs allow local source pickup to be embedded directly into the stream, eliminating a separate audio interface for basic presentation and conferencing applications.
