BUYER QUESTION
433 MHz
Often used for local connections between sensors, accessories and a compatible hub. Confirm frequency legality, indoor range, device capacity and interference conditions.
BUYER GUIDE
How to Select a Wireless Alarm Protocol
The best protocol depends on the building and response workflow. Many projects use more than one communication layer.
BUYER QUESTION
LoRa
Useful where longer-range, low-data wireless communication and repeater-based coverage are needed. Building materials and topology still require site verification.
BUYER QUESTION
Wi-Fi and Tuya
Suitable for app-connected environments with dependable local networking. Confirm supported bands, cloud dependence, account management and offline behaviour.
BUYER QUESTION
4G and GSM
Useful for remote notification through mobile networks. Confirm bands, operator support, SIM costs, call/SMS functions and backup power.
BUYER FAQ
Questions buyers should confirm
Which protocol has the longest range?
Range figures are not directly comparable unless test conditions are identical. Indoor performance depends on walls, floors, interference, antenna design and repeater placement.
Will alarms still work without internet?
Local alarm behaviour depends on the exact device and system design. It should be confirmed separately from app or remote-notification functions.
Can different protocols work together?
A compatible hub or gateway may bridge device and upstream communication layers. Compatibility must be checked by exact model and firmware version.
