The S2 remote control has a signal range of approximately 60 meters (about 197 feet) in open space. This means the remote can control accessories from a significant distance when there are no obstructions.
However, please note that the controller operates within a beam, so the signal may not be considered as "open" in all settings. During our testing, we found that the signal was effective for up to 30 meters (approximately 98 feet) in practical conditions.
