How to choose alarm add-ons
Accessories only make sense against the panel you already own, so start with compatibility. Ajax add-ons work with Ajax hubs, and Dahua expanders and modules are built for specific Dahua panels, so check the supported models on each listing.
- Range extenders and repeaters: add one when wireless detectors sit far from the hub, behind thick walls or on another floor.
- Input and output expanders: add wired zones or outputs when a panel runs out of terminals. Matching enclosures house the boards neatly.
- Transmitters and bridges: the Ajax Transmitter and MultiTransmitter bring third-party wired detectors into an Ajax system, while ocBridge Plus and uartBridge let Ajax wireless devices work with other panels.
- Communication modules: a GSM or 4G module keeps the panel reporting when broadband goes down.
- Relays: switch lights, gates or appliances from alarm events.
Pick the core panel in alarm hubs and panels first, then return here for add-ons.
