Wasted a lakh rupees on this system, have not been able to use it for more than three years since installation. Door Sensors are not fixed properly, they keep coming off. Hooter starts hooting on its own. Believe me when it hoots it is an emergency situation in and around the house. Absolute waste of investment. Repairs and customer service is also poor. Don’t go for it unless you want a hooter that can scare you and your neighbors anytime of the day or night.
