Security alarm and CCTV monitors
An RFID security system is in operation in the Balfour Library, with sensors by the exit. An alarm will sound if a book or journal is attempted to be removed from the Library without being desensitised appropriately.
Readers fitted with pacemakers shouldn't be affected by the security sensors, but if you are in any doubt, please go to Reception and ask them to contact the Senior Library Assistant in the Library Office, who will come and speak to you.
If the alarm sounds upon your exit, and you are in the Library out of hours, please check that you don't have any Library stock on you. If not, walk back and away from the sensors, and try again.
If it goes off again and you see no reason for the alarm to sound, please leave the Library and report the incident to the Senior Library Assistant the next day.
CCTV cameras are also in operation in the Library 24 hours a day and the footage recorded is monitored daily.
