The system supports video transmission between more capturing and monitoring devices, meeting the shooting needs of both small teams and professional teams.
3 Cooling Modes are Available
3 Cooling modes are available: Auto, Low, and Off. The higher the fan speed, the lower the temperature of the device casting. The fan produces very low noise (maximum noise level: 55dB). You can choose a mode that meets the needs of the actual shooting.
- Auto mode: The fan speed is adjusted according to the temperature of the device. The higher the temperature, the higher the speed, to ensure rapid heat dissipation of the device.
- Low-speed mode: The fan speed is reduced to a minimum, and the fan noise is also reduced.
- Off mode: The fan is completely turned off to totally eliminate fan noise. Use this mode when you need an absolutely quiet environment.
1 Transmitter X 2 Receivers - Efficient Monitoring Made Easy
One transmitter can work with up to two receivers. So, the system allows two parties (director, investor, lighting control, etc.) on the shooting site to simultaneously monitor the photos with high picture quality at a 12 Mbps data rate and ultra-low latency. Using the system, even a big production or live streaming team can collaborate efficiently.
Intelligent Channel Scan
Smart channel scan can be activated with a single key press. You can find out which channels are occupied at a glance, and select any interference-free channel of connection. Just rest assured that you have stable, interference-free transmission. Note: The optimum channel is automatically selected after startup and no manual selection is required.
Multiple Power Supply Options
Power can be supplied by an NP-F battery, power bank/USB changer with a Type_C plug or DC adaptor. Multiple power supply options mean that you can ensure continuous power supply in all kinds of situations.
Easy Monitoring via Mobile Devices
The system supports monitoring with an app on a phone or tablet. The app acts as a little monitor and provides 9 auxiliary functions such as brightness histogram, frame marking, and zooming. Any additional monitoring persons required temporarily can directly connect to the app without installation, which offers more convenience. You can connect up to 4 phones or tablets for monitoring at the same time.
