Call/door entry systems in GU21

Call and door entry systems help you control who enters your property, whether it’s a single home, block of flats, or commercial building.

From basic audio intercoms to advanced video entry systems, these solutions improve security and convenience for occupants.

If you’re looking to install or upgrade a call or door entry system in GU21, search with Checkatrade for checked and reviewed contractors. They can advise on the right setup for your property type and access needs to ensure a job done right.

What is a call/door entry system?

A call or door entry system is a security system that allows occupants to communicate with visitors before granting access to a property.

Systems can be audio-only or include video, keypad, fob, or smartphone-based access control.

They’re commonly used to manage entry at front doors, communal entrances, and gated access points.

Signs you might need a door entry system

  • There is no secure way to verify visitors before opening the door
  • Shared entrances are currently left unlocked
  • You want to upgrade from keys to fobs, codes, or app-based access

Maintenance of call/door entry systems
