Sony SRG-A40 4K PTZ Camera with Built-In AI and 30x/40x Clear Image Zoom (Black)

A Camera that Automatically and Naturally Shoots Video for you

With the advanced PTZ Auto Framing feature, the camera automatically track the target in a comfortable viewing with smooth Pan-Tilt-Zoom movement regardless of posture, movement and what one is wearing.

Since the camera does most of the work automatically, the operator can spend its time efficiently.

PTZ Auto Framing with built-in AI analytics

This camera harnesses powerful AI-powered video analytics that can automatically detect and track the position of a presenter within the camera frame. As the presenter moves, the camera’s pan/tilt/zoom mechanism ensures that the presenter is always framed naturally, without the need for a human camera operator to manually follow their movements.

Automatically and reliably shoots video for you

With Sony’s newly developed AI analytics algorithm, it detects and tracks the subject, even when there are several people in the frame.

Choice from three shooting modes

The camera has a choice of three shooting modes; Full body, Waist, and Close up. In each mode, you can select the center, left, or right angle of view, and the SRG-A40 and SRG-A12 can automatically track the subject in the selected optimal position.

Integrated tally lamp

The SRG-A40 and SRG-A12 feature a built-in tally lamp, just like you’d find on professional studio cameras. The lamp illuminates to give presenters visual confirmation of shooting status, or to show that PTZ Auto Framing mode is active. The lamp colour will change from Red (On Air) to Green (PTZ Auto Framing ON).

Remote control of PTZ operation

Pan/Tilt/Zoom camera movements and other functions can all be precisely controlled using the supplied IR remote controller, for convenient wireless control of PTZ functions without needing additional equipment. It can also be controlled using the optional additional RM-IP500 remote controller, just like professional broadcast cameras.

Convenient control from PC or tablet*

Camera functions can also be controlled remotely from a networked PC or tablet using our intuitive Web App.
