How it works

In 5 steps

  1. 01ArmArm the system with a keypad code, a keyfob, a contactless card or tag, the app, or a schedule.
  2. 02DetectContacts on doors and windows, motion detectors inside and glass-break detectors near glazing watch the premises. A triggered detector sends an encrypted radio signal to the hub.
  3. 03AlertThe hub checks the security mode and group, and allows the entry delay if one is set, so you can disarm on the way in.
  4. 04Siren and notifySirens sound and the hub sends alerts over Ethernet, Wi-Fi or cellular: app notifications, SMS or calls, depending on the system.
  5. 05Verify by photoPhoto-verifying detectors send a picture with the alarm, so you can tell an intruder from a false alarm. Ajax MotionCam needs a Hub 2 family hub; we check the exact hub and its firmware before you order.

Two ecosystems

Pick the hub first: Ajax or Dahua

Both are hub-based wireless systems run from a phone app. Devices do not pair across brands, so the hub decides every other part on the list.

Installation

Quoted after a site survey, or carried out by your own installer. Not in the prices above.

  • Pairing the devices to the hub and checking signal strength at each position
  • Fixing detectors, siren and keypad, and walk-testing each detector

Recurring costs

Not in the prices above. Amounts depend on the provider and plan.

Assumptions

  • One shop: entrance, back door, shop floor, store room and a glass front
  • Ajax Jeweller devices on one Ajax hub; the Hub 2 (4G) takes up to 100 devices
  • Radio ranges are for open space; signal strength is checked at each position before fixing

Prerequisites, not in this configuration

  • SIM cards and data plans, and a UPS for the router

Not included

  • Shutter protection: a shock detector or metal-body contact for rolling shutters
  • A monitoring service

Options and alternatives

  • MotionCam detectors, for a photo with each alarm
  • Shutter protection: a shock detector or metal-body contact for rolling shutters
  • Monitoring service, arranged with a provider of your choice
  • Alternative: Dahua ARC3800H Hub 2 kit and Dahua W2 detectors instead of the whole Ajax set. Do not combine hubs from both brands.
  • Alternative: Ajax Hub 2 Plus instead of the Hub 2 (4G), for Wi-Fi and up to 200 devices

Buying guidance

All parts are Ajax Jeweller devices, which pair only with Ajax hubs, and the Hub 2 (4G) takes up to 100 devices. Radio ranges are listed for open space (1,000 to 1,700 m for these devices); RCC walls, shutters and racking reduce them, so check signal strength at each position before fixing.

Details

Software, installation and growth

Software

Ajax systems are set up and used through the Ajax apps: users, security groups, rooms, automation scenarios and photo verification. Hub 2 (4G) supports up to 50 users and 32 scenarios; Hub 2 Plus raises that to 200 users and 64 scenarios. PRO accounts let an installer or monitoring company manage the system with your permission.

Dahua wireless hubs are armed and disarmed by app, keyfob or schedule, send SMS and calls to a list of numbers, link alarms to IP cameras and receive firmware updates from the cloud. The Hub 2 starter kit takes up to 8 IP cameras for alarm video. Dahua’s wired panels, such as the ARC2008C-V3, are managed over the network and from LCD keypads.

Installation considerations
  • Plan the zones. Walk through the premises and list every door, shutter, window and room that needs cover, then group them by area.
  • Hub position. Place the hub centrally and out of sight, near mains power and the router. Use Ethernet plus a SIM so there are two paths for alerts.
  • Radio range. RCC walls, metal shutters and racking reduce range. Check signal strength at each detector position before fixing it, and add a range extender such as the Ajax ReX 2 or Dahua ARA43-W2 where needed.
  • Detector placement. Mount motion detectors in corners facing across likely paths, not at windows or AC vents. For rolling shutters consider a metal-body contact such as the Dahua ARD312 or a shock detector.
  • Wired panels. Dahua’s wired and hybrid panels use cabled zones and a 12 V standby battery; route alarm cable away from mains wiring.
  • Fire safety. Wireless smoke and heat detectors give early warning, but they do not replace a fire alarm system designed to the code for your building, and an intrusion alarm must never lock an escape route.

Installation is carried out by your own installer or electrician. SecurityGearHub supplies the hardware and can advise on layout through installation advice. The wireless alarm system guide explains the choices in more depth.

Growing the system
  • More detectors. Ajax Hub and Hub 2 take up to 100 devices and Hub 2 Plus up to 200; Dahua wireless hubs take up to 150 peripherals.
  • Wider areas. Range extenders (Ajax ReX and ReX 2, Dahua ARA43-W2 and ARA46-N-W2) cover large plots and multi-floor buildings.
  • Existing wired devices. Ajax Transmitter and MultiTransmitter, or Dahua ARM310-W2 and ARM9A4-W2, bring wired detectors into the wireless system.
  • Safety detectors. Add fire and leak detectors and panic buttons from the same brand as your hub.
  • Automation. Dahua ARM7011-W2 (low-voltage dry contact) and ARM7012-W2 (mains) wireless relays switch loads from the Dahua system.
  • Wired expansion. Dahua ARC2 series panels grow with ARM808-RS input and ARM708-RS output modules.

Questions

Frequently asked

Should I choose Ajax or Dahua?

Both are hub-based wireless systems and devices cannot be mixed: Ajax Jeweller devices pair only with Ajax hubs and Dahua W2 devices only with Dahua hubs. Ajax offers a wide range of indoor, outdoor, fire and leak detectors run from the Ajax apps. Dahua offers starter kits, IP camera linkage and wired or hybrid panels.

Can I see what triggered the alarm?

Yes, with photo verification. Ajax MotionCam detectors take a photo on alarm, but they need a Hub 2 family hub; Hub (2G) and Hub (4G) do not support MotionCam. On the Dahua side, the ARD1731-W2 is a wireless motion detector with a camera, and Dahua hubs can link alarms to IP cameras.

What happens during a power cut or internet outage?

The hubs have built-in backup batteries; Ajax lists up to 15 hours of offline operation for the Hub 2 (4G) with Ethernet switched off. Fit a SIM card as well as Ethernet so alarms still get through if the broadband fails, and keep the router on a UPS.

How do I avoid false alarms?

Keep motion detectors away from AC vents, heaters and direct sunlight, use dual-technology detectors such as the Ajax MotionProtect Plus or Dahua ARD2231-W2 in difficult rooms, and walk-test every detector.

Can the alarm alert a guard or a monitoring company?

Ajax hubs support PRO accounts for installers and for installation and monitoring companies, and Dahua wireless hubs can send SMS and make calls to a list of phone numbers. SecurityGearHub supplies the hardware; monitoring is arranged with a provider of your choice.
