The Access Guard 2000 will be a standalone access unit that will read a Wi-Fi ID (MAC address) as a code for access control to a remote door or gate. It will be the same concept as a basic digital lock and entry code or a card reader and card. If the Wi-Fi ID is valid, a relay will be activated to grant access. The unit should be able to be programmed at the unit in case a local Wi-Fi network is not available. If a local Wi-Fi network is available, a mobile app should allow for remote programming of the unit.
