Ajax or Dahua alarm: which to choose for a location?

This article was machine-translated from French and is being reviewed. Prices are in Algerian dinars excl. VAT.

Ajax or Dahua alarm: for a simple location and tight budget, the Dahua kit with external siren is most affordable. It costs 55,000 DA HT (price from asloitech.com on 06/11/2026, subject to availability). Ajax is more expensive per unit, but the store lists more accessory types for system upgrades. Both are wireless alarms: a central panel receives radio signals from detectors, triggers the siren and alerts your phone. The choice depends on location size, planned expansion and budget.

Ajax or Dahua Alarm: what is common, what changes

Devices from one brand connect to the control panel of the same brand. Thus you choose the system before the detector, and do not mix ranges: an Ajax detector does not connect to a Dahua control panel, and vice‑versa. The store has 112 Dahua items (all families) and 22 Ajax items as of 06/11/2026.

Both brands use their own radio link. The Ajax (Jeweller) link operates at 868 MHz. In Dahua, the same reference exists in 433 MHz and 868 MHz: the 868 MHz version has “(868)” in its name. Control panel and detectors must share the same frequency.

The contents of the kits. The Starter kit description lists a control panel, an outdoor StreetSiren siren, a MotionProtect motion detector, a SpaceControl remote and an opening contact (“ILS”). The store page for the Dahua kit does not detail its contents. According to Dahua, the ART-ARC3000H‑03‑GW2 kit includes a control panel, a remote, an opening detector and a motion detector; the store adds an outdoor siren, according to its title. Two scenarios exist, at store price:

• If the Dahua kit from the store contains these devices, the two kits are comparable: the Starter costs 83,000 − 55,000 = 28,000 DA HT more.
• If the kit only contains the control panel and siren, an equivalent set costs 55,000 + 8,500 + 8,000 + 6,500 = 78,000 DA HT. The Starter then costs 83,000 − 78,000 = 5,000 DA HT more.

Ask for the exact kit contents before comparing.

On our quotes. The Ajax Starter kit has a median of 68,500 DA HT (17 orders, from 63,000 to 83,000), and the Dahua kit with external siren ART‑ARC3000H has a median of 55,000 DA HT (13 orders, from 51,000 to 65,000). The difference of medians is 68,500 − 55,000 = 13,500 DA HT. These are order‑of‑magnitude observations from our quotes.

System application and extension

Application. Each brand has its own app. It is used to arm, disarm, receive alerts and view history. Try it before buying: you will use it daily.

Ajax extension. The store lists a shutter detector at 13,000 DA HT, a glass break detector at 9,500 DA HT, a relay at 13,000 DA HT and a camera detector, the MotionCAM, at 24,000 DA HT. The Hub 2 Plus control panel listing shows Ethernet, mobile network, Wi‑Fi, photo verification and video streaming. The touch keyboard (22,000 DA HT) and the REX repeater (21,500 DA HT) were out of stock.

Dahua Extension. The store lists a keypad at 16,000 DA HT, a ARA43-W2 repeater at 29,000 DA HT and a camera detector ARD1731-W at 19,000 DA HT. It does not list a curtain detector or glass break detector from Dahua.

Before buying a control panel, ask how many devices it accepts: that is the limit of your extension.

When to choose Ajax, when to choose Dahua

The limits: Ajax is more expensive per detector. An Ajax motion detector costs 15,000 − 8,500 = 6,500 DA HT more than a Dahua. The store lists fewer types of Dahua accessories. In both cases, radio range is verified on site, and an alarm signals an intrusion without preventing it.
