Is the door, or any nearby door, secured via a prox-card system? If so, my first assumption is this might be an attempt to record RFID transactions.
Some RFID implementation is capturable for replay, some are 2F like challenge response plus pinpad on the fob/paddle. Consider physical lock and key plus pin / swipe / bio. Have doors audio infrared video camera record stream to offsite. Verify staff is defensive against social engineering and collect curious events. Use real end2end software openvpn / ssh to host/lan over wifi, not just silly soho style router firmwares for wlan and firewall protection. Etc. Set out some cookies for new friends :)
The device was actually right next to our RFID reader for the office door. He did manage to capture one person walk through, who then alerted me to his presence. Yeah, our netsec is best practice. Alfie -- Alfie John alfiej@fastmail.fm
