Buying Guide

Match device to threat type

Choose sensors designed for the specific risk — e.g., glass-break detectors for window entry, pull stations for manual fire activation, and signal scanners for privacy sweeps

Prioritize detection and sensitivity settings

Devices with adjustable sensitivity levels or multi-mode detection let you reduce false alarms while maintaining coverage in different environments

Check connectivity and power options

Compare wireless vs. wired setups and battery life or power requirements to ensure continuous operation where you plan to install the device

Evaluate video quality and storage

For cameras, higher resolution (e.g., 2K) and clear options for local or cloud storage improve identification and evidence value

Consider installation and tamper protection

Look for simple mounting options and tamper-detection features to keep devices secure and functioning after setup
