    Did you know your front door is the most likely point of entry for burglars? In 34% of break-ins, intruders used forced entry, spare keys or were simply brazen enough to walk through an unlocked door.

    We offer a number of electronic entry and keyless access control services and products to combat these security weaknesses at different price points to match your budget. Examples range from App controlled video door bells that can be accessed from anywhere in the world to more technical solutions such as fully integrated door intercom systems and biometric/fingerprint readers. All our solutions help give you and your family more control by allowing you to confirm who is at the door before it has to be opened.

    We Can Secure All Possible Entry Points

    Internal/external doors, garage doors, entrance gates, windows, gun cabinets, swimming pool doors, wine cellars, vaults and safes can all be fitted with access control and most readers can be discreetly positioned and even integrated into the rest of your security system.

    Intercoms and Communications Devices

    Audio intercoms and video entry systems allow you to check who is at the door and interact with them before deciding whether or not it’s safe to open the door.

    With our app, you can now do this from anywhere from your smartphone!
