- Home Alarm System Wireless Dual Passive Infrared Detector (External Antenna)
, $7.50 (https://www.amazing1.com/products/home-alarm-system-wireless-dual-passive-infrared-detector-external-antenna.html))
Product Description
These sensors detect infrared heat signatures and then send a wireless signal to alert a central alarm system, such as our JC-G02 (which can track up to 99 wireless sensors). This sensor does not emit an audible sound that can be heard.
This version has an internal style antenna, which is less obtrusive but at the cost of a slightly shorter range than an external antenna.
- On/Off LED
- Auto temperature correction
- SMT design, high RFI/EMI immunity
- Triple IR pulse technology
- Alarm delay time setting
- Uses 9V battery (not included)
- Weather-resistant enclosure (but not waterproof)
- Best for indoor use or outdoors at night (sunlight may give false alarms)
- Detection distance: up to 36 feet
- Detection width: 110° (up to 30 feet)
- Range of wireless signal: up to 300 feet (open distance)
Use several of these sensors to establish "zones" of coverage, and your central alarm system will then alert you when a zone has activity -- you can then view the area if you have surveillance cameras established, or be alert to take other action.
