This is not really an alarm as such, it is designed to aim at your noisy neighbour. if police fail to respond to a noisy neighbour then if noise is what they want, give them noise, the type of noise you cannot talk over or dance to. they either switch off their hi fi and stop their barbaric shouting and laughing at 100db or they listen to your VIPER BLAST. you have as much right to make noise as they do without police interference. So, exercise your rights!
