PTZ camera with 20x optical zoom, 3G-SDI, HDMI, NDI and composite analog output. In addition, the camera features H.264/H.265 streaming and supports NDI protocol (NDI versions only).
TheNDI Broadcast and Conference Camera, in gray, fromPTZOptics
, allows you to output up to a 1080p60 signal simultaneously via HDMI, SDI, and NDI or IP outputs (NDI and IP share the same RJ45 port). The NDI protocol, NewTek's innovative IP technology, gives you low-latency access to audio and video devices anywhere on your network for various A/V applications. You won't be restricted to sources connected directly to a single system. The 12X-NDI comes with a NewTek NDI license, so you're set to go right out of the box. The camera also has a composite output that can be used on its own (without any of the other outputs at the same time) to deliver 576i/480i resolution.
The NDI has a 3.5 - 42.3mm lens providing a 12x zoom range which is ideal for smaller meeting rooms and classrooms. The NDI versions of the PTZOptics 12x cameras are ideal for streaming applications, houses of worship, sports streaming, live productions and events, and when cable runs might be an issue (when you'd rather run Ethernet cables instead of coax). The camera does well in low-light conditions owing to a fast f/1.8 - 2.8 lens aperture and minimum illumination requirement of only 0.5 lux. On top of this, built-in wide dynamic range and 2D and 3D noise reduction further enhance the conferencing experience. The camera is completely open-source, so developers can customize everything as they prefer using simple HTML.
The NDI can be powered over PoE or using the included power supply. It offers RS-232 and RS-485 serial control, an audio line-in for HDMI and NDI/IP streams, and 10 presets via the included IR remote control or 255 via serial or IP control.

PTZ valdoma kamera (pan-tilt-zoom) yra vaizdo stebėjimo įrenginys, kurį galima valdyti nuotoliniu būdu. Ši kamera turi tris pagrindines funkcijas: pan (posūkis), tilt (lenkimas) ir zoom (artinti/nutolinti). Per posūkio ir lenkimo funkcijas, PTZ kamera gali judėti horizontaliai ir vertikaliai, padengdama didelį stebėjimo plotą. Artinimo funkcija leidžia priartinti vaizdą, identifikuoti smulkius objektus ar atpažinti veidus. Šios kameros gali būti valdomos specialiai sukurtu valdymo įrenginiu arba per kompiuterį. Tai yra populiarios stebėjimo sistemos dalis, naudojama saugumo, stebėjimo ar net video konferencijų tikslais.
2. Kaip tinkamai valdyti PTZ kameras?
Norint tinkamai valdyti PTZ (pan-tilt-zoom) kameras svarbu suprasti valdymo priemones. Dauguma atvejų naudojamas specialus valdymo įrenginys arba programa, leidžianti nuotoliniu būdu valdyti posūkio, lenkimo ir artinimo funkcijas. Valdymas gali būti vykdomas rankiniu būdu per dedikuotą įrenginį arba automatiškai, naudojant iš anksto nustatytus maršrutus. PTZ kameros gali būti integruotos į išmaniuosius telefonus ar kompiuterius, o kai kurios net palaiko valdymą balsu. Valdydami PTZ kameras, turite įsitikinti, kad suprantate valdymo sąsają ir naudojate visas įmanomas funkcijas efektyviam stebėjimui ir žymėjimui.
