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.\u003c\/p\u003e\u003cp\u003eSDI 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.\u003c\/p\u003e\u003cp\u003eWith 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.\u003c\/p\u003e","brand":"Alfatron Electronics, Inc.","offers":[{"title":"Default Title","offer_id":52450026062008,"sku":"124266","price":1979.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0871\/7382\/4696\/files\/124266_Alfatron-Electronics-ALF-20X-SD-TC-Auto-Tracking-PTZ-Camera-With-SDI_ALT01sqr.jpg?v=1788969239","url":"https:\/\/soundpro.com\/products\/alfatron-electronics-alf-20x-sd-tc","provider":"SoundPro","version":"1.0","type":"link"}
