The usefulness of the security cameras cannot be overemphasized in the area of giving adequate security cover to our homes. The increasing rate at which crimes of unimaginable magnitudes are been carried out is giving a worrisome has become a worrisome development to governments and people all over the world.
It is interesting to note that the worst crimes are perpetrated under the cover of darkness. If are to go for a security camera that will give you real cover, then you have to go for one that will be effective 24 hrs in the day-the hours of darkness inclusive. When you go online to purchase the model that will serve you best, you will see many of them in differing shades and colors. Which one is the best bet for you?
In answer to the above question, we are not going to give a categorical answer, but rather, we are going to delve into the technology of how these cameras produce results in the hours of darkness and you will use that at the end of our interactions to get the particular model that best suits features that we have discussed. Let us go straight into business.
There are a couple of different types of night security cameras. We shall be taking a look at the technology expected from each of them starting with the most common among them:
Infrared Night Vision (IR)
This is the most common among the security cameras that are online. The technology here is based on infrared light which is manipulated to give a clear infra-red vision at night. Take a look at the external design of the security cameras around you, notice the handful of small LED bulbs; it represents the IR lights. When darkness comes, the lights are turned on and the technology is such that it acts as a flood type light. This will submerge the field of view of the camera with infrared light.
The infrared light is totally invisible to the naked eye. It will look as if a bright light is covering the area; but in actual fact, your naked eyes cannot see it. The eye can differentiate quickly between the colors of black and white than with other colors; therefore the night vision images of the security cameras are seen in black and white in other to get a sharp vision. The best of the night vision cameras use the technology of the monochrome filter so that it will be pretty easy to see the image clearly at night.
There are several types of light that can aid our vision at night. So, why the choice of the infrared light by the security cameras to aid night vision? The answer to that is not farfetched; it is only the infrared light that is visible to the naked eye. Take a look at the night camera, it does not have the technology of the infra cut filter, you cannot get desired maximum benefits from such. It will automatically detect the daylight and then apply the filter to block the incoming IR light during the day; it will, therefore, enable the colors looking for accuracy.
Where you strategically locate the camera close to your window, the reflection of the IR light will be indicated on the window.
We shall look at another concept of the night vision camera different from the concept that we have just considered above.
The Tube Intensifier
Aside from the security cameras that uses the technology of the IR, another concept that you can rely on in your such for the best features in a night camera that will give you expected results is the category that uses the Tube Intensifier technology. The use of sensitive camera sensors is heightened here in order to increase the intensity of the light.
In more advanced models of the night security camera, the available light is made to access the night vision goggles which will be transformed into electrons which in turn will finally transform it into electronic signals. A technology of photomultiplier is included which makes the light to pass through a phosphor screen to create flashes of light which will ultimately result in a brighter image.
All the colors of the light that enters the glasses are then transformed into a shade taking the color green and this will give an ionic view of the color green to the eye. The technology in the night vision camera is made possible because, at night, the color is black at night which is very dark. Blocking all the light at that dark moment in time is an impossibility unless you are making an attempt to actually block it.
Go to a dark corner in your room or go out at night with your camera and take a long exposure shot with it in the dark. Print out the image and you will be surprised at the brightness of the said image which will make a mockery of the shot you actually took in the dark. The result is so because the camera takes all the light around it and amplified such to get the results. This is the technology on which the security night camera is built on.
This type of night vision can only be found in night vision glasses. The majority of the security cameras that has night vision capabilities are based on Infrared technology. The vision is clearer with it and the price of the unit is cheaper. So on account of its performance and the pocket-friendly price on each unit, it will be ideal to go for security cameras that come with the technology of infrared.
How Do Security Cameras Capture Their Image Even In Pitch Darkness?
The night vision technology of most security cameras enables them to capture the image even when it is dark outside. The question is: how is this achieved? Taking a look at the night vision footage of the ghost hunting TV shows, how they capture the black and white or the black and green footages? It is through the night vision technology which the night vision security cameras now make use of to capture images under the cover of darkness.
The Technology Of The Infrared
It has been mentioned earlier that infrared technology is the most common and cheapest among the two so far discussed. It is therefore advised that when you go online, the search should be focused on the cameras that use IR technology. In other to establish this fact the more, let us go further to see how things actually work with this technology.
Have you ever looked at the front view of a security camera? If you have, notice that the front of the camera is surrounded by some small LED bulbs. Those are the IR bulbs. When it gets dark outside; the lights will turn on and their effects within their surroundings will be like flood light of some sorts.
You have been shown the technicalities that are involved in the workings of the security camera. You have also learned that it is best to rely on the models that make use of IR technology. We shall go back to the puzzle in the opening paragraphs of this article which borders on the choice of the particular service provider that will give you the best on offer. There are several models of security cameras online that uses infrared technology. But which one among them can you trust? Where is that model that is custom designed to serve your best purpose?
