very good product fast delivery good communication with the seller
The package arrived quickly, within a week as promised. The supply was from Spain, so there were no additional taxes. The product looks very good at first glance. It took me quite some time to connect the VTO outdoor unit to the existing VTH indoor unit. I had to update the firmware in SIP 2.0 on the existing VTH unit, otherwise it didn't work. I used the VDPConfig program for all settings. There I also found an excel table, where you enter all the settings and easily import it into the program, and you automatically configure both units. All of these settings were quite a challenge. All this time, technical and sales support was available to help me. He answered within hours. Thanks again for all the help, I recommend them. The product successfully meets all my expectations. It works smoothly, quality sound and picture. Perhaps the phone button could be more exposed. So far no problems.
