Intercoms that work with the door, the gate and your phone
An intercom is the one security device visitors actually interact with, so it gets judged on whether it's easy to answer and whether the gate opens when it should.
Answering on a phone changes what it's for
A traditional intercom rings a handset inside the house. One that also reaches your phone lets you answer the door from anywhere — useful for deliveries, tradespeople and letting family in when you're out. It also means the intercom becomes a camera at your entry point, recording who called even when nobody answered.
Gate and door release is where the wiring gets real
Releasing a gate motor or an electric strike means the intercom has to switch a circuit, often some distance away, sometimes with its own power supply and its own failure behaviour. On existing gates the controller may or may not expose a usable trigger input. This is the part of an intercom job that determines whether it's straightforward or not, and it's worth establishing before the job rather than during it.
Apartments and multi-tenant sites are a different problem
Multi-tenant systems have to handle a directory, multiple answering points, and often building management access on the same door. Retrofitting into an existing block usually means working with cabling that's already there and not always documented. These jobs are assessed on site rather than quoted from a photo of the panel.
What you get on every job
Labelled cabling
Cables are identified, so the next person to open the cabinet — whether that's us in three years or someone else entirely — can tell what goes where without tracing every run by hand. It costs a few minutes during the install and saves hours later.
A camera position and coverage plan
A site plan showing where each camera sits and what it covers, agreed before anything is installed. It's how the design conversation happens — you can see what you're getting and move a camera on paper rather than after it's on the wall. It stays useful afterwards as a record of what was agreed.
Your credentials, in writing
Admin passwords, app logins and account ownership are yours and are handed over documented. This shouldn't be worth mentioning, but installers withholding credentials to protect their service work is common enough that it's worth being explicit: it's your system, and you'll be able to administer it or hand it to someone else.
A commissioning test record
A record of what was tested and the result — night footage actually reviewed, detectors walk-tested, remote access checked from outside your network. It comes from commissioning industrial plant, where nothing is considered finished until it's been proven under the conditions it has to work in. The same principle applies to a system whose whole job is to work at 2am.
Common questions
Can I answer the intercom on my phone?
Yes, on the systems currently installed. It's set up and tested before handover, including from outside your home network so you know it works when you're actually away.
Can it open my existing gate?
Usually, if the gate controller has an input that can be triggered. Older or unusual controllers occasionally don't, which is why the gate is checked before committing to it.
Does the intercom record?
Most current systems record a snapshot or short clip of each call, including missed ones. Where an intercom is integrated with a CCTV system it can record continuously like any other camera.
