Smart Alarms & Sensors

Alarm sensors are the detectors, contacts and sirens that make up an intruder alarm, reporting to a control panel or hub that raises the alarm. This range covers wireless and wired PIR, dual-tech and glass-break detectors, door contacts, shock sensors and sirens from makers including Ajax, Hikvision AX PRO, Pyronix, Texecom, Optex and GJD, and the ESP Fort smart alarm system with kits, hub, keypad and accessories.

Choosing Smart Alarms & Sensors

Add sensors that belong to the same system as the panel or hub they will report to, then choose the devices for the areas they protect.

Motion detectors

PIR detectors sense body heat moving across their field of view. Pyronix KX10DP is a wired pet-immune PIR covering 10m at 85°, Hikvision DS-PDC15-EG2-WE is a wireless curtain PIR for 15 m, and ceiling detectors such as the Texecom Capture CD-W cover 360°. Dual-tech detectors such as the Optex FlipX FLX-S-DT add microwave to PIR.

Doors, windows and glass

Magnetic contacts, such as the Pyronix MCNANO-WE and Hikvision DS-PDMCX-E-WE outdoor contact rated IP66, signal when a door or window opens. Shock sensors such as the Pyronix NANO/SHOCK-WE and glass-break detectors such as the Hikvision DS-PDBG8-EG2-WE detect an attack before entry.

Outdoor detection

The GJD630 D-TECT is a battery-powered universal outdoor quad PIR rated IP65, for gardens and yards before anyone reaches the building.

Frequently asked questions

What is a smart alarm?

A smart alarm is an intruder alarm that connects to the internet through a hub, so you can arm it, disarm it and receive alerts using a phone app. Wireless sensors such as motion detectors and door contacts report to the hub, which sounds a siren and sends a notification when something is triggered. The range here includes smart alarm kits, sensors and sirens.

What can home sensors detect?

Home sensors can detect intruders and changes in the indoor environment, depending on the type. Motion detectors pick up movement, door and window contacts sense opening, and shock or glass-break sensors respond to an attack on a window. Environmental sensors can track temperature, humidity and carbon dioxide levels. The range here includes motion, opening, glass-break and environmental sensors.

How does smart alarm monitoring work?

Smart alarm monitoring usually means the hub sends an alert to your phone when a sensor is triggered, so you can check the event and respond yourself. Some systems can also report to a professional monitoring centre that calls keyholders or the police. A hub with a mobile-data backup such as GSM can keep sending alerts if the broadband connection drops.

How do you set up a smart alarm?

Start by placing the hub in a central spot, connecting it to your router or Wi-Fi and installing the maker's app. Pair the sensors with the hub, then fit motion detectors in rooms and hallways and contacts on entry doors and windows. Test the devices in the app and set entry delays and user codes before arming the system.
