We found a considerable variation in the price of video intercoms. The amount of features, the brand and the size of the display are among the main causes of this. The cheapest models cost around £ 350, but already have quality, and the most expensive, approximately £ 1.000. Security companies can be good options to buy a video intercom, as well as general shops, such as Multicoisas. We recommend that you make the purchase over the internet, prioritizing the Brazilian Amazon. Also review Amazon International and Mercado Livre.
