The Accsoon CineView SE is not your average wireless video transmitter. Not even close. Boasting transmission ranges of up to 1200 feet to up to 4 receivers or smart devices - the CineView SE makes social distancing on a professional set a breeze. Now you can expand the CineView SE via the dedicated CineView SE receiver units. You can pair up to 4 receiver units to one transmitter allowing for video transmission with nearly undetectable lag up to 1200 feet away. Just like the latest CineView systems - the CineView SE receiver units are powered by either Sony NP-F style batteries, 7.4v-16.8v DC input, or USB-C power. These options allow the CineView SE to endure long duration shooting via either option. You can also hot-swap NP-F batteries by quickly temporarily switching to DC or USB-C power while changing them. Adding an additional receiver to your CineView SE system is easy. Just rotate the group number on the receiver to match the group number on the transmitter, and the transmitter and receiver will automatically pair once powered on. ***Please note that the CineView SE receiver units are for CineView SE or HE systems only. This unit will not work with the CineView Quad or CineEye transmitters. ***
