The color change sequence remains the same and is repeated approximately every minute. 'At the end' of the cycle, the device always 12x flashes very light, what would happen as sure as good as ever on TV! Even for me as a 'non-burglar' was this device in less than 15min. clear as a 'fake TV' to recognize! So you weigh the potential burglars know the device more in security than to deter them!
