Once panic when a security light has started whether a home security camera has started recording because the movement detector of the device has activated it, but there is nothing there?
It is not uncommon for a movement detector Phantom movement to take up, but what does this cause? A simple malfunction, a spirit or something else?
There are different types of motion sensors, but the type found in motion detection cameras, lights and sensors used in home security systems are generally a type of passive infrared sensor (PIR) sensor called a Pyro -electric sensor.
One thing we know about spirits is that they are not liked to be seen. They are often heard but not seen, their presence is felt, or they are only invisible entities that try to communicate ghost hunters with the use of paranormal tools and Ouija boards. We also know that Ghost can go through solid objects. This tells us that spirits are not solid and that they have no mass.
PIRs work by detecting the small amounts of heat that is emitted from the human body in the form of infrared radiation. This is why they are called passive sensors, they do not have a light source as a night vision camera. When an intruder comes home, the introduction of their body heat is sufficient to activate the alarm.
They can also activate if something much smaller such as a pet moves through the room, although the sensitivity of a PIR can generally be adjusted to ignore pets.
The sensors cannot “see” or detect visibly light, so the only way it could detect a spirit is if the entity radiated heat in a similar amount as a living human body. This is a bit problematic because incidents of people who feel a warm ghost through it are not reported, in fact it is the opposite – cold spots are often associated with ghost parties.
Here is the sciencebit …
To have something broadcast, it must be a solid object and it needs a mass, something that we have established that spirits do not have. How do we know this? Well, all thanks to a well -known comparison attributed to Albert Einstein … E = Mc².
To simplify this and to prevent it from getting too deep into a physics lesson, the E is in the comparison of energy, so this tells us that the energy of an object, whether it is a star or a spirit, is equal to MX C². The M refers to the mass of the object. In the case of a spirit, the masses are zero. So ignoring the slightly more complicated c², everything multiplied by zero is equal to zero.
A spirit with zero mass (m) has zero energy (e).
It is not as easy as this, because light has no mass, but it gets its energy because of its movement and actually falls under another lesser -known comparison, E = PC. An object that is at rest and has no mass has not only has no energy, it also does not exist according to the rules of the universe.
So if it is not a ghost setting of a movement detector in an empty room, what is it then?
There are a few things that can lead to a motion detector giving a false alarm if there is nothing. Because lights are a heat source, even LED lighting to a certain extent, a light that is switched on as a movement by a motion detector can be done.
The sunlight that enters a window or wiping over a room can also be sufficient to activate an alarm. Normally this happens slowly and gradually enough that the detector ignores it, but it can happen in certain situations such as blinds or curtains that are opened, blocks a blowing tree outside the light, or a parked vehicle outside a window that drove away and let sunlight in.
Fabric caught in a ray of sunshine can also activate a movement detector. If the dust is clearly illuminated by the warm sunlight and close to the detector, the dust from the point of view seems to be much larger and hotter than other objects in the room that cause a false alarm.
Although these kinds of movement detectors may not have a chance to detect a spirit, they are not entirely useless on a ghost hunt. Since the most observed phenomenon about ghost hunt tends to be doors, objects that move or are thrown, or inexplicable punches and pony, a PIR can help you detect or even disprove these things.
Placing motion sensors around a location in empty rooms can help you if you hear a sound. If you are in another room and you hear a bang, you may not be able to figure out where the sound came from, but an alarm that sounds, you will be able to warn in the exact room if a movement has occurred, whether that is paranormal or simply attacks something.
