Product Information
The Ocean Reef GAMMA ALPHA HD is a hardwired, full-duplex underwater audio and video communication system that lets a surface operator talk with one or two divers while watching a live camera feed on a 13" full HD screen. It records audio and video internally through a programmable DVR with 320GB of storage, expandable to 1TB, and runs on a 12V rechargeable battery.
Who it is for
This system is built for surface-supplied dive communication setups where a topside operator needs real-time audio and video contact with divers wearing Ocean Reef professional Full-Face Masks. The GAMMA ALPHA HD connects to the ALPHA PRO X-DIVERS underwater communication unit and can display split-screen video when two divers are connected at once.
Key details
The surface unit has a 13-inch full HD, backlit, anti-reflective screen with digital audio/video output via HDMI and a USB-A connection that lets the system be recognized as a plug-and-play external webcam on PC or Mac (USB-A cable not included). The included AHD 1080p wide angle camera has a 120-degree field of view, a 1/3-inch Sony CMOS sensor, a 2.8mm board lens, and a housing rated to 40m/130ft. Backup recording is possible via USB-A to an external pen drive or hard drive, neither of which is included. On battery, stand-by autonomy is 24 hours, maximum recharge time is 2 hours 45 minutes, and run time ranges from 5 hours 20 minutes with one video and one audio channel over a 50m cable down to 4 hours 30 minutes with two video and two audio channels over 200m cables.
Compatibility and sizing
The GAMMA ALPHA HD pairs with the ALPHA PRO X-DIVERS underwater communication unit and connects to Ocean Reef professional Full-Face Masks through an Extender Frame or NACS mount.
