Qolsys QS1230-840 Motion Sensor


Monitor A Large Room For Motion


Detect people moving up to 30 feet away, while ignoring small pets up to 40 pounds, with the Qolsys IQ Wireless S-Line Encrypted Pet Immune Motion Sensor (AKA the IQ Motion-S). When motion is detected, this wireless battery-powered sensor sends a notification to your compatible control panel/receiver (319.5 MHz wireless frequency), such as a GE/Interlogix Panel (NetworX, Simon, etc.) or a Qolsys IQ Panel. The sensor can also be included in automation rules. For example, you could create a rule that turns on a light when someone enters the room. The sensor easily mounts at a variety of angles in a wall corner or on a shelf with the included hardware, providing coverage for a large area.

  • Detects human motion up to 30 feet x 50 feet (80 degrees horizontally)
  • Ignores pets up to 40 pounds to prevent false alarms
  • Compatible with 319.5 MHz wireless panels, such as GE/Interlogix or Qolsys IQ

About S-Line Encryption

Qolsys wireless devices that feature S-Line (“Secure Line”) technology offer advanced encryption to safeguard your wireless signals against hacking.

The technology employs an advanced encryption scheme between the wireless sensor/device and the control panel to ensure that wireless event transmissions are always unique, preventing and eliminating common replay attacks (when an unscrupulous person uses an easy-to-purchase software-defined radio or “listening device” to replay events that were previously sent by wireless devices paired with a security system.) At time of pairing, S-Line technology passes a unique key which enables the encryption algorithm for unique event transmissions, thereby preventing such replay attacks.
