Reach Cam 4K REA430-Reach Cam

Product introduction

Reach Cam 4K REA430 is a 4K UHD PTZ camera for classrooms, lecture halls, training rooms and conference spaces. One camera family covers three room sizes: the 12X model starts at an 80.4° horizontal wide angle for small and medium rooms, the 25X model reaches 59.2° and the 31X model 59° for the back of a large hall. All three use a SONY CMOS sensor with 8.29 MP effective pixels and output 4K@60 with 3D noise reduction and a signal-to-noise ratio of 50 dB or better.

Tracking is done inside the camera. A built-in high-speed processor runs the Reach image analysis algorithm, so the camera needs no tracking computer, no wearable sensor and no operator: choose real-time tracking and the camera follows a speaker walking at 1.3–1.7 m/s at up to 6–7 m distance, or choose area tracking and define up to six zones, each one a preset the camera holds and returns to as the speaker moves between the lectern, the whiteboard and the audience.

The camera carries HDMI 2.0, 3G-SDI, USB 2.0 and PoE LAN on the same chassis, and all four can output 4K audio and video at the same time — HDMI to the room display, SDI to a production switcher, USB to a soft codec or lecture capture appliance and LAN to a streaming or recording platform. Video is compressed with H.265 or H.264 on the network port and MJPEG, H.264, H.265, YUY2 or NV12 on USB, and the camera speaks ONVIF, GB/T28181, RTSP and RTMP as well as VISCA over IP.

Product views

The camera head sits on a pan / tilt base with ±110° horizontal and −30° to +30° vertical travel. The rear panel carries HDMI, 3G-SDI, USB 2.0, LAN with PoE, a dual-channel 3.5 mm audio input, RS232 in and out, RS422 / RS485, a rotary DIP switch for address and protocol, the power switch and the DC 12 V input.

Reach Cam 4K REA430 — 4K AI auto-tracking PTZ camera

AI auto tracking without extra hardware

Two tracking modes cover two very different rooms, and both are configured from the camera menu or the web page:

• Real-time tracking — locks on a single speaker and follows them continuously. Tracking distance reaches 6–7 m and the algorithm keeps up with a presenter walking at 1.3–1.7 m/s, so a lecturer can walk from the podium to the screen without leaving the frame.
• Area tracking — up to six areas can be stored, within ±110° horizontally and ±27° vertically. The camera cuts to the preset of the area where the speaker is standing, which is the natural choice for a teaching wall, a demonstration bench and a student question zone.

Tracking runs on the camera processor, so the PTZ keeps working — and keeps tracking — even if the recorder or the control network is offline.

Applications

Conference rooms, lecture halls, training and simulation rooms, courtrooms, telemedicine suites, government briefing rooms, broadcast and streaming studios, and hybrid classrooms.

Product features

4K imaging with full manual control

• 4K UHD at up to 60 fps (3840 × 2160), 8.29 MP effective pixels, 16:9.
• SONY CMOS sensor: 1/2.5 inch on the 12X model, 1/1.8 inch on the 25X and 31X models, for a cleaner picture in dim rooms.
• Minimum illumination 0.05 lux at F1.8 with AGC on; 3D digital noise reduction; S/N ratio ≥ 50 dB.
• White balance auto / manual / one-push / specified colour temperature; exposure auto, manual, shutter priority, aperture priority or brightness priority; backlight compensation and dynamic range adjustable.
• Image adjustment for brightness, chroma, saturation, contrast, sharpness and black-and-white mode.

Three optical zoom ranges, one installation

• 12X: f = 3.85–43.06 mm, 80.4° horizontal wide angle — a whole small room in one shot.
• 25X: f = 7.1–171.95 mm, 59.2° wide angle, 1/1.8 inch sensor.
• 31X: f = 6.91–214.64 mm, 59° wide angle, for the last row of a large auditorium.
• Advanced autofocus algorithm: focus is acquired quickly, accurately and stably, without hunting on a moving subject.

Four simultaneous 4K outputs

• HDMI 2.0: 3840×2160@60/50/25/59.94/29.97, 1080P@60/50/30/25/59.94/29.97, 1080I and 720P.
• 3G-SDI: 1080P@60/50/30/25/59.94/29.97, 1080I@60/50/59.94, 720P@60/50/59.94 for production and long cable runs.
• USB 2.0: UVC / UAC video class device with main and sub stream at the same time — MJPEG, H.264, H.265, YUY2 or NV12 up to 3840×2160@30.
• LAN with PoE: H.265 or H.264 over a 10/100/1000M port, powered and streamed over one cable.

Audio and network

• Dual-channel 3.5 mm line input, 32 kHz / 44.1 kHz / 48 kHz sampling; AAC audio compression.
• Audio embedded in HDMI, SDI, USB 2.0 and LAN outputs.
• ONVIF, GB/T28181, RTSP, RTMP, RTP multicast and VISCA over IP; RTMP push to streaming servers such as Wowza or FMS.

Control and integration

• VISCA, PELCO-D and PELCO-P with automatic protocol detection.
• RS232 in and out, with RS232 cascade for daisy-chaining cameras in an installation; RS422 (RS485 compatible) output.
• Rotary DIP switch for camera address and protocol, set at the back of the camera without a computer.
