What is VOX mode?
VOX mode is a voice reactive mode in baby monitor. It is a highly convenient feature in baby monitors, leveraging the latest advancements in voice recognition technology. In VOX mode, the monitor screen will be dark when the camera stays at a quiet volume level for 30 seconds. During this standby period, the video feed is temporarily paused. However, the microphone remains active, constantly monitoring for any sounds in baby room. The screen will wake up and video run again when the camera detect sounds above VOX level( VOX-H: 60db±3 VOX-M: 65db±3 VOX-L: 70db±3). This not only preserves battery life but also reduces unnecessary screen glare, creating a more comfortable sleep environment for baby and parent.
This intelligent feature is especially beneficial for parents who prefer a hands-off approach to baby monitoring. With VOX mode engaged, parents can rest assured that they will be promptly alerted to any activity in the babys room, without having to constantly check on the monitor.
Its worth noting that while VOX mode is designed to maximize battery efficiency, its crucial to maintain regular checks on the monitors battery status. Periodic recharging is essential to ensure consistent performance and peace of mind for parents. Additionally, parents should familiarize themselves with the monitors other features and settings to maximize its utility and effectiveness in baby monitoring.
