  Passive Infrared Sensor  
An alternative to sensor pads in bed monitoring. The PIR alarm has a thin, curtain-like motion detector beam, which monitors a narrow area beside the bed. When the beam is interrupted, the sensor detects motion and triggers the alarm. As with all contactless devices there are no infection control issue. The PIR sensor can be set up as an stand-alone alarm unit, or forward signals to a fall monitor or caregiver pager to remove&nbsp;in-room&nbsp;alarm noise.

  Features :  &nbsp; 	 LED status indicator (Red - Alarm / Blinking Red - Low Battery / Green - Pause) 	 Can be set up as an stand-alone alarm unit (Internal alarm) 	 Wireless works with a fall monitor, pager or central panel. Range up to 200m (600 feet)&nbsp;&nbsp; 	 Pause mode allows caregiver to tend the patient without triggering an alarm 	 Automatically re-arms if no movement is detected in 15 sec. 	 Easy reset button 	 Adjustable detection range 	 Horizontal or vertical detection options 	 3xAA type battery operated 	 Low battery alert 	 DC (6V) input option

You can now control your audio-visual devices from a greater distance even when you are in another room. Infrared (IR) remote controls have a limited range and generally only function in the same room. However, this remote control extender will allow you to expand the signal transmission of your IR remote-controlled devices at a distance of up to 40m. With an outstanding performance, the gadget operates perfectly even through walls, doors and corners while converting IR signal to RF signal.

Features:   Use an internal transmitter that converts your remote IR signal into a radio frequency (RF) signal.   Efficiently differentiate diverse RF signals and avoid interference.   Control audio-visual equipment up to 50m away even through walls, doors, floors and doors.   IR-RF exchange method allows you to control equipment such as satellite box, TV, VCR from anywhere in the house.   Deliver consistent signal with no interference.   Infrared extender cable allows placing the receiver in a closed space or out of sight field.   Convert an IR signal to RF and back to IR signal.   No direct line of sight needed.   With ID learning and selection function.   Mains power.   Applicable to various IR remote controls.   Compatible with most brand of A/V equipments.   With operating status indicator: learning procedure.   One more IR receiver can be added to control more rooms.  Technical specification:   Frequency: 433.92MHz.   Transmitted power: &le;10dBm.   Sensitivity: -108dBm.   Working voltage: 110/220V AC (AC/DC adapter).   Temperature: -10℃-60℃.
