You cannot monitor twins (and triplets) in the same cot, because the Movement Sensor Pad is so sensitive it will pick up the movements from each baby. The Sensor Pad is designed to detect movement and it cannot differentiate which baby the movement is coming from.
This would mean that if there was no movement detected for example from baby 1, the monitor will not alarm as the Sensor Pad will still be detecting movement from baby 2 (and 3).
In addition you cannot use more than one Sensor Pad in the cot (i.e. one pad under each baby) as the pad is that sensitive it can detect movement over the whole of the surface of the mattress, from corner to corner and not just baby lying above it.
To explain the alarm to you – with one Sensor Pad in a cot with one baby, if no movement is detected on the surface of the mattress for 15 seconds you will hear the:
• Main Alarm – this is a series of loud continuous beeps from both the Nursery/Camera Unit & Parent Unit (if switched on). This indicates that your monitor has not re-established your baby’s sleeping pattern.
You can use a simple combination of Angelcare monitors for twins (and triplets), however it is not possible to connect any monitors together whatever the model, they will independently of each other. You would need 2 (3) separate monitors.
To check the compatibility when using more than one monitor see the following link where you can check the options that are available for you
