Our verdict

ADT suits UK homeowners who want a professionally monitored alarm with cameras and a video doorbell on one account, and who will accept an installer visit. It is the only option here built around a monitored model, with product types covering alarm, camera, video doorbell and smoke alarm.

Pros and cons

Pros

  • Professional monitoring is included, and the model is listed as monitored, which is the main difference from self-install brands like Annke.
  • Product types span alarm, camera, video doorbell and smoke alarm, so alarms and video can sit on one account.
  • The floodlight camera reaches a resolution of 2k and runs on battery and wired power, giving a choice of battery or wired placement.
  • Support runs on phone and help centre, so phone help is available alongside a help centre.

Cons

  • Installation is required, which rules out self-fitting and puts an installer visit at the start of the setup.
  • Support runs on phone and help centre only, with no live chat or email channel listed.
  • The range is narrower than The Home Security Superstore, which also lists smart locks and personal alarms alongside alarm, camera and video doorbell.
  • Smart locks are absent from the product types, so Aqara covers a gap in the line-up.

Who it suits

  • Homeowners who want a response service rather than app-only alerts.
  • Households wanting an alarm, cameras and a video doorbell covered together.
  • People who are happy to have an installer fit the equipment in the UK.

Who should look elsewhere

  • Renters or buyers who want to fit equipment themselves, since installation is required.
  • Anyone after smart locks or personal alarms, which The Home Security Superstore lists and ADT does not.
  • Shoppers who want live chat or email support, since ADT offers phone and help centre only.

Core features

ADT is built around professional monitoring, and the model is listed as monitored, so alerts are handled by a monitoring service rather than by the phone alone. The product types on offer are alarm, camera and video doorbell, which covers an alarm, a camera, a video doorbell and a smoke alarm in one line-up. For outdoor coverage, the floodlight camera records at a resolution of 2k and draws power from battery and wired, so it can run on a battery or be wired in. Installation is required, which is the trade-off that comes with a monitored setup: the equipment is fitted for you rather than self-installed. Anyone comparing self-install brands should weigh that against the choice of Annke, whose range is limited to cameras and video doorbells.

The company behind it

The legal entity behind the service is ADT Fire & Security plc, and the headquarters country is GB, so the operation is UK based rather than a global brand running a single worldwide plan. That matters for anyone outside the country, since the product range and monitoring plans are tied to the UK market. Customer support is handled through phone and help centre, which means a phone line and a help centre are the routes available for existing customers. The company behind ADT is a long-established fire and security business, and the alarm, camera and video doorbell lines are sold as part of the same account.

Frequently asked questions

What does ADT include in its alarm systems?+

The product types listed are alarm, camera and video doorbell, so a package can cover an alarm, a camera, a video doorbell and a smoke alarm. Professional monitoring is part of the setup, and the model is listed as monitored. That makes ADT a fuller package than a camera-only purchase.

Do I need an installer to set up ADT equipment?+

Yes, installation is required for the equipment ADT sells, including its video doorbells and cameras. The benefit is that the system is configured as part of a monitored setup rather than self-fitted. Shoppers who want to install hardware themselves should look at a self-install brand instead.

How is ADT's alarm monitored?+

Professional monitoring is included, and the model is listed as monitored rather than self-managed. Alerts are handled by a monitoring service rather than by the app alone. Across the alarm systems on the site, monitoring fees sit at a median of €9.38 a month.

What resolution do ADT cameras record at?+

The floodlight camera records at a resolution of 2k. It can run on battery and wired power, so it works as a battery unit or can be wired in for a fixed position. That choice matters for a front or back door where mains power is close by.

How can I contact ADT support?+

Existing customers can reach support through phone and help centre, which covers a phone line and a help centre. Live chat and email are not part of that list, so phone is the faster route for anything urgent. Help centre articles are the option for setup questions.

Which country does ADT operate in?+

The headquarters country is GB, and the legal entity is ADT Fire & Security plc. The range and monitoring plans are therefore aimed at the UK market. Buyers outside the country should expect the equipment and plans to differ.

Does ADT sell smart locks?+

Smart locks are not among the alarm, camera and video doorbell on offer, which covers alarm, camera, video doorbell and smoke alarm. For locks, Aqara lists smart locks in its product types. ADT is the stronger fit for a monitored alarm with video rather than for door access control.
