it could be a very VFM product, but turned out to be a logistical nightmare with sending back and forth two units, until I sourced a much more expensive dahua controller. There were two listings, one that mentioned WIFI but the photo of the board had no controller, and one that had a photo with WIFI, but did not mention it in the description. The app is nowhere to be found, and anyway were it to be found is cloud only. These are all BS. Both came with rusted screws. Seriously, don't know what secukey does with their products, even contacted the Chinese HQ for information; still don't know. Anyway, went for a dahua solution, where the keypad uses rs485 with AES256 for communication and the internal unit has a dedicated web controller with all kinds of encryptions. Anything else, is just not secure. Also, neither is the wiegand protocol safe anymore, we're not living in the 70s.
