Installed Properly. First Time.
Smart security cameras and video doorbells are only as good as their installation. A poorly positioned camera, a loose mount, or a doorbell left running on battery when hardwiring is possible — these are the details that matter. Multrex installs security devices correctly: right position, right fixings, right power setup, and fully connected to your app before we leave.
Hardwired Installation
The best long-term solution. Mains-powered devices never need charging, deliver continuous recording capability, and are significantly more reliable in cold weather when battery performance drops.
- No batteries to replace or recharge
- Supports 24/7 continuous recording
- Required for floodlight cameras
- Can replace existing wired doorbells
- Concealed cabling available
Battery Installation
Ideal where running cable isn't practical — rented properties, listed buildings, garages, or temporary setups. Battery devices offer full flexibility on placement without any electrical work.
- No cable runs or electrical work needed
- Works anywhere with Wi-Fi signal
- Ideal for renters and listed properties
- Correct angle and height for best detection
- Weatherproof mounting and fixings

Our Process
What You Can Expect
From your first call to the finished job, here is how our security camera installation service works.
Tell us which device you have (or are planning to buy), the location you want it mounted, and whether you prefer battery or hardwired.
We advise on the best mounting position for coverage, detection angle, and Wi-Fi signal strength before booking.
On the day, we check the wall for cables and pipes, then mount the device securely with the correct fixings for the surface.
For hardwired installs, we connect to your mains supply or existing doorbell wiring and conceal cables neatly.
We connect the device to your Wi-Fi, complete the app setup, test motion zones and live view, then walk you through the controls.
Insider Advice
Helpful Hints & Tips
Position for detection, not just view
A camera pointing down a path detects movement earlier than one aimed directly at the door. Positioning matters as much as placement height — we advise on the right angle for each location.
Wi-Fi signal is everything
A camera installed at the edge of your Wi-Fi range will disconnect constantly and miss events. We check signal strength at the intended mounting point before committing to a location.
Hardwire floodlight cameras — always
Floodlight cameras draw significantly more power than standard cameras. Battery-powered floodlight alternatives exist but drain quickly. Mains connection is strongly recommended for these devices.
Height matters for facial recognition
Most manufacturers recommend 2.1–3m mounting height for outdoor cameras. Too high and the camera looks down at the top of heads. Too low and it's easy to tamper with.
