Buying Guide: How to Choose a No-WiFi-Required Security System
- Connectivity redundancy: Look for systems with GSM/4G backup or cellular modules to maintain alerts when WiFi is down.
- Expansion and customization: Ensure the kit supports adding sensors for doors, windows, motion, and other critical areas, plus remote controls or keypads if desired.
- App and remote access: Confirm compatibility with your preferred apps (Tuya/Smart Life) and the ability to arm/disarm remotely without relying solely on WiFi.
- Power and backup: Check for backup batteries and easy recharging to keep the system armed during outages.
- Sound and deterrence: A loud siren (e.g., 110–120 dB) helps deter intruders and signals neighbors during events.
- Camera integration: If video verification matters, choose a kit with an integrated camera or compatibility with camera modules and cloud verification.
- Installation: Consider DIY-install suitability, complexity of sensor placement, and whether professional installation is needed for optimal coverage.
- Voice assistants: If you use Alexa or Google Assistant, verify compatibility for convenient voice control of arming and status checks.
- Costs: Evaluate total ownership including sensors, monthly service (if any), and potential future expansion expenses.
