PTC-305NDI is a professional PTZ video camera with 20x optical zoom characterized by a 4K 50 / 59.94 / 60p resolution to adapt to the most varied areas of use: video conferences, distance learning, university lessons, meetings in boardrooms/boardrooms, places of worship, broadcasting, medical, etc.
Unlike the PTC-300NDI, it also adopts the NDI | HX3 network protocol as well as NDI | HX2, a flexible and versatile solution that supports high-quality, low-latency, frame-accurate video over standard Ethernet networks, and integrates it with OBS, Wirecast, vMix, xSplit and NDI Studio Monitor software applications.
Another peculiarity of the PTC-305NDI is given by auto-tracking. If you are filming multiple people, you can choose one of these for automatic tracking; once connected to the camera, only the designated person will be tracked, avoiding interference with others going back and forth, or with desks and large objects. The built-in PID algorithm can detect the movement speed of the identified object and automatically adjust the corresponding pan, tilt and zoom speeds of the camera so that the movement of the lens is smooth, avoiding common camera shake problems, jerky or unexpected stops.
This PTZ can be easily controlled via the traditional RS-422/RS-232 serial port using the 4-channel RMC-180 camera controller of the same brand, IP remote control via DVIP (proprietary Datavideo protocol) or Sony VISCA over IP and finally by adopting PTZ View Assist. This is an App that can control up to 4 cameras simultaneously via DVIP; you can intuitively configure and recall presets and adjust white balance, focus and iris. The app, for iOS and Android, can decode live streaming via RTSP, SRT and NDI | HX3. Easily monitor live streaming video and promptly set parameters in one application. The PTC-305NDI enables dual streaming output for A/V market applications, so you can easily stream to Facebook (RTMPS) and YouTube at the same time. It also works with dvCloud.
As regards the opto/electronic compartment, it boasts a 1/1.8" CMOS sensor, larger than that of competing models, synonymous with excellent performance in modest lighting conditions. Larger dimensions, for the same number of pixels, mean better S/N ratio, and therefore less video noise with higher overall image quality. We therefore find a 20x optical zoom (16x digital) associated with a particularly bright lens (f/1.58 – f/3.95) in relation to its wide focal range. The presence of a powerful optical zoom allows you to get closer to the subject even when the camera is very far from it, which makes them particularly useful for large rooms or auditoriums.
The 4K video output interfaces are HDMI 2.0, IP up to 2160p 50/60 fps and also 3G-SDI up to 1080p 60/50 fps and there is also support for simultaneous 2160p and 1080p video output (3G-SDI). There is also an audio in / line in input (switchable on the web user interface). Finally, the PTC-305NDI supports PoE for easy installation. Simply use a single CAT 6 cable to power the PTZ.
A green / red Tally lamp to show preview and program status for broadcast applications completes the features.
