2-in-1 Movement & Sound baby monitor, which detects even the most subtle sounds and movements from your child with the SensorPad. The Angelcare Movement & Sound Monitor uses 8 channels and 2 frequencies to ensure the crystal clear transmission, as well as both volume control and vibration alert to ensure you can adjust the sound levels to suit both you and your baby, ensuring you can monitor them with the sound off. There is also the added reassuring audio 'tic' function to let you know that your monitor is still looking after your baby even when they're sleeping silently.
