Hi I installed above product with 3 door sensors and 2 motion sensors. The sales executive one Naveen and Shilpa told me that in case of intrusion on away mode blank call would call would come on registered mobile I.e after 1st year if call center services are not renewed. However now they are unable to confirm, if this feature is there or not. If it is not there, this product is useless without subcribing to annual call center charges. Which is recurring expense you would incur annually.
