Why we build security
around Ajax Systems.

What is Ajax Systems?

Ajax is a professional wireless security platform: a hub, detectors, keypads, sirens and cameras that run from one app and one central station. Ajax Systems describes its range as intrusion protection, comfort and automation, fire and life safety, and video surveillance1. It reports over 4.5 million end users in more than 180 countries2. Rivas Technology Group is an Ajax Systems dealer, listed on ajax.systems for wireless intrusion protection, outdoor solutions and video surveillance. You own every device from the day it goes on the wall, and nothing about the system depends on a contract.

How does Ajax verify an alarm?

It sends a photo of what tripped the detector, so an operator acts on evidence instead of a bare signal. The chain runs like this:

1. The hub polls every device. Detectors talk to the hub over Ajax's Jeweller radio, rated to 2,000 m in open space. The hub checks each one at an interval between 12 and 300 seconds, 36 seconds by default (Hub 2 manual). A detector that goes quiet is reported before the gap matters.
2. A MotionCam trips and takes pictures. MotionCam delivers its first photo within 9 seconds. It follows with a series of two to five images (MotionCam, Ajax demo guide).
3. The hub keeps reporting. Hub 2 Plus runs Ethernet, Wi-Fi and two cellular SIM channels at once (Hub 2 Plus). Ajax states that in offline mode the system operates the way other professional systems do, on the hub's battery (Why Ajax).
4. The signal is encrypted and authenticated. Every Jeweller transmission uses block-cipher encryption. Each device is authenticated every session (Ajax Hub). Every device carries a tamper switch, so opening or removing one is itself an event.
5. The photos reach the people who act. With professional monitoring, the central station sees the series and dispatches with a description. Without it, the same photos reach your phone. Hub 2 Plus supports up to 200 users, so a family, a property manager or a shop's whole staff can be on one system.

That chain is why the security hub says security should verify before anyone responds.

Ajax against Ring, SimpliSafe and ADT

The difference is structural: who owns the hardware, whether a contract is attached, what the hub falls back on, and whether the alarm arrives with a picture. Where we cite a competitor figure, the source sits beside it; where we do not have one, read the plan before comparing.

Up front, Ring costs less. One UK review compared a Ring starter kit at about £100 with an installed Ajax kit at £380 to £4905, and that gap is directional for US buyers. A London comparison reaches the same split we do: Ring for low entry cost and Alexa, Ajax for professional grade, cellular backup and photo verification6. If price on day one is the whole decision, buy the kit. If you want an alarm police can act on and no contract to leave, that is the case for Ajax.

Who monitors it?

Becklar, a UL-listed central station staffed 24 hours a day. It receives the alarm and the photo series together, verifies the event, calls your contact list in order, and dispatches police, fire or medical when the event is real. UL 827 is the standard central stations are certified against (UL Solutions). Monitoring is month to month with no contract; cancel it and the system keeps working, with you watching instead of the station. Self-monitoring through the Ajax app carries no fee (Why Ajax).

Does Ajax work with Control4?

Yes. As a Control4 Authorized Dealer, listed on Control4's integrator map, we link the Ajax hub to Control4 through a driver. You arm and disarm from Control4 keypads, touch screens and the app. A MotionCam alarm brings up the exterior lights and puts the camera on the kitchen screen. Ajax keeps its own app and its own path to the station, so the alarm never depends on the automation. Details are on the Control4 page.

What drives the cost?

The number of openings and rooms covered, how many detectors take photos, whether outdoor devices and cameras are included, and whether you add monitoring. Ajax hardware carries a 24-month warranty from date of sale, batteries excluded (Ajax warranty), plus our 90-day workmanship warranty. Kit prices, installation and the monthly rate are published on Ajax alarm system cost; the instant quote gives you a figure in minutes.
