Frequently asked questions You have an Ajax alarm system, or you are about to get one, and you want to know how it works in daily use. This page contains the questions we receive most often as an Ajax partner about arming, alarms, expanding, maintenance and moving house. The answers have been checked against the manuals of […]
Expanding An AirShield system grows with you. You start with a starter kit and then connect up to 150 wireless devices to a hub: extra detectors, controls, sirens, smoke and water detectors, home automation and even your old wired alarm. Everything comes together in the free DMSS app and stays up to date through cloud updates. In this article we set out a […]
The hub is the heart of your Ajax alarm system: it connects all your detectors, reports alarms and keeps in contact with the app and the alarm receiving centre. Ajax has several hubs, from a compact entry-level model to a top model for large premises. Below, you can compare them quickly and choose the hub that suits your situation. Quick choice […]
Outdoor security The best security raises the alarm before anyone is inside. With the outdoor detectors from Dahua AirShield you protect your garden, driveway or yard: weatherproof detectors with dual sensor technology spot an intruder at the façade, and the camera variant sends photos straight away. Combined with an outdoor siren and, if desired, Dahua cameras, you deter intruders before […]
Pets An alarm system and pets go together well. Pet-friendly motion detectors are designed to ignore a cat or dog in most cases, and with photo verification you can see straight away whether an alert was caused by your pet or by something else. You can never rule out false alarms completely: good placement and the right […]
Installation An Ajax system is wireless, so you can easily install it yourself, without any chasing or breaking up of walls. You mount the detectors and enrol them via the app. If you would rather have it done for you, or you need advice and a neat handover, our VEB-approved installers will fit and configure it for you. The choice […]
Ajax starter kits An Ajax kit is an affordable bundle of a hub with a set of detectors and controls, ready to use and without any chasing or breaking up of walls. The StarterKit is compact and ideal for getting started; the Basic kit covers an entire home with more detectors, a siren and a keypad. The Cam variants add photo verification and the Plus variants […]
Wireless or wired A good wireless alarm protects your property just as reliably as a wired system; the difference lies mainly in installation, expansion, maintenance and features. For most homes and businesses, the wireless Dahua AirShield is quicker to install and more flexible. A traditional wired alarm keeps its place in […]
Costs Yes, an Ajax alarm system works entirely without a subscription. You operate and manage everything in the free Ajax app, and push notifications in the event of an alarm are free too. Two things may incur optional extra costs: an M2M SIM card for mobile back-up and an alarm receiving centre subscription for professional follow-up. Both are choices, not obligations. Below you can read exactly what is free […]
Ajax hubs The hub is the heart of your Ajax alarm system: all detectors, sirens and controls communicate with it. Ajax has four wireless hubs for homes and businesses: the Hub, the Hub 2, the Hub 2 Plus and the Hub BP. They differ mainly in three respects: photo verification, the number of communication channels and the power supply. Below you can see them […]
