What is PIR distance?

What is PIR distance?

With PIR Motion Detection Cameras, movement means the detection of a warm moving object within the image, optimized for humans, on both temperature range and size. PIR detection range is 10m (32ft).

How does a LDR sensor work?

When the light level decreases, the resistance of the LDR increases. As this resistance increases in relation to the other Resistor, which has a fixed resistance, it causes the voltage dropped across the LDR to also increase.

How do I reduce the sensitivity of my PIR Sensor?

Use masking tape around the sensor for a temporary adjustment and locate the area which works for your sensitivity. Then for a permanent solution remove the tape and just paint over the area where the masking tape was placed.

Can I cover a PIR sensor?

A quick solution that customers have said works well is to use black electrical tape to cover part of the sensor. Start by covering the edge of the sensor on the side you want to keep out of the detection area and use small pieces of tape to block it out.

What can trigger a PIR sensor?

What are some of the top causes of false alarms for motion sensors?

• Flying or crawling insects; spiders like to make homes in corners and anchor their webs to the sensors.
• Pets.
• Curtains or plants blown by air conditioning or heaters.
• Low batteries.
• Ceiling fans.
• Objects moving near motion sensors.

How do you trick a motion sensor light to stay on?

Often, the wind blowing through leaves and branches can cause the motion sensor to detect motion, causing the light to stay on. Turn off the switch which operates the motion sensor light. Keep the switch off for 1 to 2 seconds and then turn the light switch on again.

How high up should you put a motion sensor?

How High Should a Motion Detector Be? Overall, a motion detector should be mounted on the wall, between 6 and 8 feet high. Some people also put their motion detectors on or near the ceiling.

How do you prevent motion sensors?

Block the sensors with a piece of paper or cardboard. This will not work for all motion sensors, but it can be attempted in cases where there may not be very much room free from their line of sight. Place the paper or cardboard in front of the sensors very slowly, then attach it to the unit before proceeding.

Why did my motion sensor go off?

Other naturally occurring incidents that can set off your motion detectors are dappled patterns, such as sunlight through moving tree leaves, dust being caught in a sunbeam, or slow-moving light changes, such as the sun moving across the sky.

How many motion sensors do I need?

Motion sensors monitor a fairly large space, like a standard-sized living room, so you’ll generally never need multiple sensors in one room. They typically detect movement in the monitored space, or they can even detect body heat using infrared technology.

Do motion sensors have cameras?

Some motion detectors work hand-in-hand with video security systems. Using this technology, the camera will only record when the sensor is tripped. This saves on memory for your security camera and, of course, it can come in handy to have video evidence of a break-in.

Do motion sensors work through glass?

The motion sensor is based on passive infrared detection, therefore it works through clear glass.

What is the difference between an active and passive motion sensor?

Unlike an active motion sensor, a passive motion sensor does not have a transmitter. Instead of measuring a constant reflection, the sensor detects motion based on a perceived increase of radiation in its environment.

Do PIR sensors work in daylight?

PIR sensors are used for burglar alarms. They work fine in daylight, and won’t have light sensors to disable them during the day.

Can PIR sensor detect cars?

The passive type of detector simply measures a change in the flux of the earth’s magnetic field caused by the passage of a vehicle. These detectors can only detect moving vehicles, so they cannot be used as presence detectors.
