Unix is sneaking into the most unlikely places these days, and now Schlage Electronics Inc, Santa Clara, California has signed to use Hawthorne, New York-based Basic Applications Inc’s Unix software in its proximity access control systems – that means systems that stop people going into controlled areas without authorisation: designed specifically for integrated security systems, the Unix software will expand the capabilities of the Schlage products to perform other security and financial management functions such as closed circuit television control, cardholder photograph capture, storage and retrieval, time and attendance, parking revenue control, lift control, guard tour monitoring and such; the software will be offered on Hewlett-Packard Co HP 9000 machines.
