Shop for security systems, there are SVN, Hikvision cameras, burglar alarm, access control. There is a product in stock, friendly and professional staff, I recommend it.
Everything seems to be fine with the products, but there were problems with the managers. They don't care about the client, because they always have enough of them. If they do not fulfill their promises, they can simply send and say that they will refund the money for the product. And you've been waiting for this product for a month, and they just don't fulfill the agreement.
