Photos of our work
Can video doorbells run on existing doorbell wiring?
Yes, many modern video doorbells can connect to existing low voltage doorbell transformers. If existing cabling is absent or degraded, we run fresh power cabling to a dedicated mains transformer.
Where should CCTV cameras be positioned on terraced properties?
Cameras are positioned to focus on your property perimeter, front paths and rear access doors. We align cameras to respect neighbouring privacy while securing your entry points.
Do wireless alarms require mains power?
Wireless alarm sensors run on batteries, but the main control hub and external siren generally connect to a permanent mains power connection to maintain continuous operation.
Can door entry systems be fitted to period flats?
Yes, we fit audio and video door entry systems into older flats and converted buildings, coordinating with the existing electrical intake and door frame dimensions.
