Sensitivity: A sliding scale between 1 and 50. The number refers to the number of pixels (as a percentage) that have to change between frames.
What sensitivity should I use for security cameras?
It is recommended to select a Sensitivity between 30~70. Threshold determines how much motion is required to trigger an event. If the amount of motion exceeds the threshold, an event occurs. It is recommended to select a Threshold between 10~50.
How do I adjust the sensitivity on my Swann camera?
If your motion detection is not triggering enough, then you need to adjust the sensitivity UP or DOWN depending on what result you want. This is done in the MENU > SYSTEM > MOTION > AREA setting. Adjust the motion sensitivity up to be more sensitive, or down to be less sensitive.
Whats the difference between PIR motion and detection?
PIR or Passive Infrared motion sensors are designed to reliably detect people, large pets & other large warm moving objects.True Detect is more than just motion sensing but also includes thermal heat sensing. The True Detect PIR sensor is triggered when a security camera senses heat whether from people or cars.
What does Pir mean on Swann?
The PIR (Passive Infrared) motion sensors are designed for security & optimised to reliably detect people, large pets & other large warm moving objects. This means security cameras smart enough to detect humans rather than sheets blowing in the wind.
What is sensitivity threshold?
Threshold sensitivity: the minimum write beam intensity required to record an image on the read-out beam.This time is limited by the decay or erasure of the recorded image.
How do you keep bugs from setting off security cameras?
Keep Your Security Cameras Bug-Free
- Apply lubricants to the outside case of your camera.
- Attach a dryer sheet to the camera.
- Disable the LED lights.
- Loop a flea collar around your camera.
- Spray bug repellent around cameras.
- Sweep camera areas weekly.
- Use a fan to prevent spider webs.
Does Swann Security record all the time?
The DVR comes out of the box set to record continuously, however you’ll find that motion detection is already enabled for all channels.
What is the difference between mainstream and Substream?
Mainstream and substream are two different video streams used to view your camera footage. Mainstream: is the primary video feed.Substream provides a lower quality video stream, and is typically used to stream video to computers, smartphones, or tablets over the Internet.
What is PIR level?
PIRs are basically made of a pyroelectric sensor (which you can see below as the round metal can with a rectangular crystal in the center), which can detect levels of infrared radiation. Everything emits some low level radiation, and the hotter something is, the more radiation is emitted.
How accurate is PIR sensor?
Pyroelectric infrared (PIR) sensors are the most popular presence detectors.Experimental results reveal that the C-PIR sensor can detect stationary occupants for up to 4.0 m and moving occupants for up to 8.0 m, while maintaining an accuracy of 100%.
What does PIR delay mean?
The reason for this undesirable image is that your camera was too close to the trail for the camera’s delay, meaning by the time the motion sensor triggered something was moving and told the camera to fire, the animal had already moved through most of the camera’s field of view, leaving you with a picture of its rump
What is PID and PIR?
To Understand PIR Detectors
PIR stands for passive infrared, and it’s also called PID for passive infrared detector. It’s an electronic sensor based on heat energy detection that is commonly used for PIR activated IP cameras, lights and alarms.
What is PIR detection mode?
Passive infrared (PIR) sensors use a pair of pyroelectric sensors to detect heat energy in the surrounding environment. These two sensors sit beside each other, and when the signal differential between the two sensors changes (if a person enters the room, for example), the sensor will engage.
Can rain set off security lights?
Almost all security lights use some form of sensor to detect movement.The cheapest security lights will work with a basic motion sensor that detects the movement of any object. These are problematic because anything can set them off heavy rain or snow, moving objects, or swaying branches.
What is the difference between threshold and sensitivity?
Think about it this way: sensitivity is a measurement of the amount of change in a camera’s field of view that qualifies as potential motion detection, and threshold is how much of that motion needs to occur in order to actually trigger the alarm.
What does motion detection sensitivity mean?
Sensitivity determines how drastic a change in the view of the camera must be to trigger a clip. For example, a cloud moving slowly across the screen may trigger a video clip if the sensitivity is set high enough, whereas a lower sensitivity may not trigger a recording for the same amount of motion.
What is threshold setting?
A threshold setting is a percentage that controls the total number of data values that are required to meet the threshold before an inference is made by the system.This means that there is a possibility that the inference might be wrong.
Are bugs attracted to infrared light?
Unfortunately, insects are attracted to infrared light and will fly in front of the camera’s view. Lowering the sensitivity on the camera will help somewhat, but if insects fly in close, the IR will reflect off of them and still trigger motion.
Do insects see infrared light?
Infrared light has longer wavelengths and lower energy than visible light and cannot be seen with the human eye. Mosquitoes, vampire bats, bed bugs, and some snake and beetle species, however, can use portions of the infrared spectrum for vision. Sometimes humans can see infrared energy in the form of heat.
Why are wasps attracted to security cameras?
Most security cameras emit a faint magnetic field. You might not notice the signal, but wasps are highly attracted to these types of magnetic transmissions.Standard pest control practices prevent wasps from flocking around cameras.
