Is Your Door Entry System Still Doing Its Job?
Door entry system upgrades across Surrey, KT, GU and SW postcode areas
Analogue door entry systems have served many properties well for decades, but older systems can become unreliable, difficult to repair and limited compared with modern security needs.
If your system has poor video quality, faulty handsets, intermittent calls or no remote access, it may be time to consider upgrading to a modern IP video door entry system. These systems do more than replace old hardware — they give you better control over who enters the building, clearer visitor identification and more flexible management for residents, staff or property managers.
Why Older Door Entry Systems Fall Short
The signs are often gradual. The picture becomes unclear, the handset takes several attempts to connect, the entrance panel stops lighting properly, or spare parts become harder to source.
These are not just inconvenience issues. A door entry system is there to help control access, protect residents and support day-to-day building security. If you cannot clearly see or speak to visitors before releasing the door, the system is no longer doing its job properly.

No remote access or smartphone answering
No visitor recording or event history
Faulty handsets, buttons or entrance panels

Why Upgrade to an IP Door Entry System?
A modern IP door entry system gives better image quality, more reliable communication and improved control over building access. For flats, offices, HMOs and commercial premises, it can also make management much easier by allowing authorised users to answer calls, review activity and control access remotely.
In many cases, existing cabling may be reusable, but this depends on the condition of the wiring and the type of system already installed. A site survey is the best way to confirm the most practical upgrade route.
