Access Control

Access Control


The Steadfast Group provides a range of access control systems suitable to all types of buildings and applications. 

Our access control systems can be interfaced with intruder alarms to enable the automatic setting of individual areas or buildings. PC controlled access systems can also be used for time and attendance reasons and fire system roll call purposes.


All our access systems are designed, installed and maintained to NACOSS GOLD (NSI) Codes of Practice and relevant British Standards. This ensures a fail-safe operation in the event of a power failure where access from a building is a priority.

A properly designed and installed CCTV system is an excellent deterrent to the would-be criminal, and, just as importantly, can provide visible evidence of any wrongdoing that can easily be stored and passed to officials, such as the Police.

The Steadfast Group designs, installs, commissions and maintains CCTV systems:

  •  Simple one-camera and monitor observation systems

  •  Complex multiple CCTV camera systems

  •  Full-functional pan, tilt and zoom cameras

  •  Off site control and monitoring and DV-IP connectivity


Wireless Systems

Our wireless CCTV System is ideal to protect remote and harsh environments.  All system components operate on batteries, allowing for completely wireless video security. 


Since sites, compounds and most outdoor sites are uncontrolled environments, portability means that our CCTV Towers can be placed on any site, in any environment. The Tower can then be moved and placed in different areas, depending on your security needs at any time.

Our selected CCTV systems have integrated cameras which generate 10 second video clips upon activation. 

The activated alarms and video clips will be sent directly to stake holders on their smartphones and to our state of the art 24-hour Control Room, where an operator can respond and manage alarms.

It's portability means it can be moved around as the project evolves - before potentially being installed months later at a brand new site... No power? No problem.
