When a Repair Becomes an Upgrade

Sometimes older panels or peripherals are past their best. We’ll never push you—just explain your options:

Add App Control to Your Existing System

Keep your current kit and upgrade for phone control so you can set/unset and receive alerts. Often a quick, tidy retrofit.

Migrate to Wireless AX PRO

A clean, modern system with no messy cables on show, excellent range and Hik-Connect app as standard. Ideal if frequent faults or missing parts are driving you mad.

Add Extra Detectors

Extend coverage with PIRs, door/window contacts, shocks and outdoor beams—wireless options keep disruption low and finishes neat.

Repairs rarely need any chasing. If we add devices, we favour wireless peripherals to keep things neat.

Often yes—we can retrofit a communicator and set up the app so you can set/unset and receive notifications.
