The thumb rocker controller also provides richer control functions than the remote control, such as pan tilt calibration and channel selection, so that you can set and shoot at one go. Quick installation and convenient setup The thumb rocker controller can be clamped on the pan tilt handle or installed in other suitable places without the assistance of installation tools. It can be used immediately after the signal is connected. OLED screen information is clear at a glance The bright and clear OLED screen allows you to easily view the current status of PTZ. With the pressure sensing button, you can easily operate or set the ronin-m PTZ. Long range remote control The built-in battery of the thumb rocker controller can guarantee 18 hours of working time, and can work all day after being fully charged. The thumb rocker controller provides a control distance of up to 60 meters, allowing you to remotely control ronin-m and capture unique lenses. Two people cooperate and switch freely The thumb rocker controller can be operated simultaneously with the remote control. The priority setting determines the controller's active control over the PTZ. The second PTZ hand can intervene in shooting when necessary to control the camera movement and make the shooting more perfect.
