Product Description
Environmental and performance features:
- Long-range detection: Provides up to 100m outdoor detection range.
- AGC circuit: Automatically adjusts sensitivity to compensate for gradual signal strength changes caused by weather conditions.
- Environmental protection: Includes features to protect against rain, dust, and insects. Many also have frost, snow, and dew protection or optional heating units for cold climates.
- Lightning and surge resistance: Protects the device from damage caused by power surges and lightning strikes.
- Visible light cutoff: Effectively blocks external visible light sources, like headlights, from causing false alarms.
- Adjustable interruption period: The time the beam must be broken to trigger an alarm can be adjusted, for example, to ignore jumping cats while still detecting human intruders.
Security and reliability features
- Dual beams: Requires two beams to be broken simultaneously to trigger an alarm, which significantly reduces false alarms caused by small objects, animals, or falling leaves.
- Double modulation: Uses a double-modulated pulse to distinguish the real signal from interference from sunlight or other artificial light sources.
- Synchronized pulse: Synchronizes the timing of the transmitter and receiver to improve reliability.
- Adjustable beam frequencies: Often offers multiple selectable beam frequencies to prevent interference between multiple sensors.
- Anti-tamper: May include a tamper output that triggers an alarm if the cover is detached.
Alignment and installation features
- Dual ring sight: Provides a clear view for easier beam alignment.
- Wireless alignment checker: Some models may include a wireless tool for easier and more accurate alignment.
