Mobile Division

Our mobile division covers Mobile-Patrol Alarm-Response and Keyholding, as well as Static and Mobile Guarding Services. At Capricorn Security, we pride ourselves in offering high value low cost services, to the retail, commercial, industrial and domestic sectors.

We understand that for businesses, having to rely on your own staff to keep keys safe or to be available at unsociable hours of the night could prove difficult, and in the event of fire or a break-in, the consequences could cost you dearly.
