What Is PIR Sensitivity?
To understand PIR sensitivity, you need to first understand some basic physics. Everything around us - including ourselves - emits infrared radiation. These infrared waves cannot be seen with the human eye but can be detected as heat. Now, a Passive Infrared (PIR) camera measures the differences in infrared radiation around it to detect objects or motion.
PIR sensitivity will determine how easily the sensors detect a difference in infrared radiation around them. A higher PIR sensitivity will detect the smallest amounts of infrared radiation, like a passing animal, while a lower one will only be triggered by large amounts of heat, like a person or a car. PIR cameras will also only record or send an alert when a change in infrared radiation is found. This reduces false alarms triggered by traditional motion detection security systems. Now, let’s see what we can learn about radar.
What Is Radar Motion Detection?
Unlike PIR detection, which simply monitors disturbances in infrared waves, radar detection emits waves to find movement. A radar detector will send out radio waves, and when these waves hit an object, they bounce back, and the radar device will analyze the data in the reflected waves to detect motion.
This phenomenon is called the Doppler Effect and allows the radar sensor to note the speed, distance, and direction of any movement. Both PIR and radar detection offer unique and insightful surveillance on their own. Now, let’s take a look at some of the benefits of using both motion detection methods at the same time.
Key Benefits of Using a PIR + Radar Camera
A comprehensive security camera system will use all of the best features available to keep you safe. With a dual PIR and radar detection security camera, each system covers the limits of the other to provide complete protection. To prove that point, let’s take a look at some of the main benefits of using a PIR and radar camera:
Extended Range: The average PIR sensor can also detect infrared radiation up to 20 meters away and with a 90-degree field of view. However, radar sensors can reach up to 30 meters with a 360-degree field of view, allowing you to cover a much wider range and compensate for where the PIR camera can’t.
Compensated Coverage: Criminals could move slowly to avoid spiking heat signals, which is where the radar kicks in to detect movement.
Reduced False Alarms: Using a dual camera with optimal PIR sensitivity will drastically cut down false alarms or triggers by swaying branches or the neighborhood cat.
Energy Efficiency: A PIR camera will only activate and begin recording once motion is detected. This makes them more energy efficient and long-lasting.
Real-Time Notifications: By using a PIR and radar camera system, you’re immediately notified when any movement or thermal signature is picked up. This gives you more time to call for help or react.
Environmental Endurance: PIR sensors alone might fail to detect anything in extreme weather, while radar can offer backup and spot small movements without being affected by light or weather changes. Radar detection also spots movement on the other side of thin walls or glass, which makes them much more versatile.
Now that we know some of the key benefits of pairing up PIR sensors and radar detection security, we can look at the best dual camera setup available today.
Best PIR and Radar Outdoor Security Camera 4K Recommendation
The Baseus S2 4K security camera is a solar-powered outdoor security camera that embodies the innovative and intelligent designs made popular by the company. As the first 4K camera from Baseus, the wireless S2 also comes fitted with ultra-HD visuals and has 8MP clarity with 8 times zoom and a 145° wide-angle view. This ensures clearer details from up to 12 meters away.
The camera also activates a full-color night spotlight vision for up to 8 meters away when a threat is detected. To prevent false alarms, the S2 uses AI algorithms to recognize strange faces, vehicles, or movement while ignoring up to 10 whitelisted faces. With both radar and PIR sensors, the camera also eliminates 99% of irrelevant triggers like branches or wind.
The industry’s first automatic sun-tracking system also keeps the camera’s solar panels in the range of sunlight to ensure 900mAh of energy generated each day, making it twice as efficient as a fixed solar panel. Added to the hefty 7,800mAh battery, which supports 150 days of coverage, this provides 24/7 protection.
With AES+RSA encrypted local and expandable storage of 256GB and no hidden fees, you can enjoy fully CCPA-compliant privacy for your data. The camera can also be controlled by your Google Home or Alexa smart assistant and can withstand extreme weather conditions with an IP67 rating, making it ideal for yards, driveways, and outdoor areas.
