Southwest Microwave Introduces the Advanced Model 420 Passive Infrared Sensor

Southwest Microwave is pleased to announce the introduction of the advanced Model 420 Passive Infrared (PIR) Sensor for specialized outdoor intrusion detection applications.

With detection capability to 122 m (400 ft), Model 420 provides a four-zone, continuous and gap-free curtain sensing pattern that detects intruders by identifying the temperature (heat radiation) difference between background scene and intruder. The pattern includes long, medium and short range detection segments, plus a controllable Creep Field that protects the area surrounding the mounting pole.

“This unique feature eliminates the detection ‘dead zone’ characteristic of traditional passive infrared sensors,” explained Bob Kirkaldie, Southwest Microwave’s director of sales. “Furthermore, minimal clear zone requirements for the detection pattern make this sensor ideal for intrusion detection in very narrow corridors.”

The latest in detector and signal processing technology plus precision mirror optics enable Model 420 to operate in broad-ranging environmental conditions. The sensor offers Double Optical Filtering, Digital Signal Processing, Signal Shape Analysis and Adaptive Threshold Decoding, each of which contributes to ensuring reliable operation under changing climatic conditions.

“Nuisance alarms from rain, snow, wind, and fog are virtually eliminated due to this product’s highly sophisticated feature set,” said Kirkaldie.

Reinforcing Model 420’s performance reliability is the sensor’s ease of operation. Set-up and adjustment are achieved via user-friendly installation software with flexible controls to simplify alignment, signal check and routine maintenance.

Model 420 electronics and optics are housed in a rugged IP65 heavy-duty plastic enclosure. An internally regulated heater connected to sensor electronics and operating from the supply voltage prevents the unit’s optical surface from fogging or frosting in cold weather. A universal mounting bracket allows mounting to flat surfaces or 100 mm (4 in) O.D. posts.

  • Just as Expected

    GSX produced a wonderful tradeshow earlier this week. Monday was surprisingly strong in the morning, and the afternoon wasn’t bad at all. That’s Monday’s results and asking attendees to travel on Sunday. Just a quick hint, no one wants to give up their weekend to travel and set up an exhibit booth. I’m just saying. Read Now

    I have been looking forward to this year’s GSX show in New Orleans, the Cresent City, or if you prefer The Big Easy. It seems like quite a while since we’ve been here. Twenty years ago, ASIS, as it was known then was literally washed out of the city by someone known as Katrina. It is a good thing to come back to NOLA. Read Now

  • From Monitors to Mission Control

    Security Operations Centers (SOC) were once defined by rows of static monitors, each displaying a single feed with operators quietly watching for issues. That model has become obsolete. Incidents evolve too quickly, data comes from multiple locations, and decisions must be made in seconds—not minutes. Read Now

    ResponderLink

    Shooter Detection Systems (SDS), an Alarm.com company and a global leader in gunshot detection solutions, has introduced ResponderLink, a groundbreaking new 911 notification service for gunshot events. ResponderLink completes the circle from detection to 911 notification to first responder awareness, giving law enforcement enhanced situational intelligence they urgently need to save lives. Integrating SDS’s proven gunshot detection system with Noonlight’s SendPolice platform, ResponderLink is the first solution to automatically deliver real-time gunshot detection data to 911 call centers and first responders. When shots are detected, the 911 dispatching center, also known as the Public Safety Answering Point or PSAP, is contacted based on the gunfire location, enabling faster initiation of life-saving emergency protocols.
