I purchased a video door phone from Zicom in bangalore in July 2014. I first got the cabling done with the cable that zicom provided to me along with their kit. I got the installation of the door phone and the display unit done by the zicom representative.
The representative pointed out problems with the display unit that it does not switch off after 40 seconds and that the voice is not audible outside. To get this problem addressed, zicom took 4 full months. The customer support person took my display unit and outdoor unit for checking. Its been a month and they dont know when the replacement will arrive!
Requests to atleast install the older unit in the interim is not being entertained either. There are other players available in the market such as godrej, please check those out. Atleast quality of Zicom equipment is assuredly bad! please refrain from buying this product
