Surveillance cameras are one of the most popular elements in security. And what about night cameras? Well three quarters of the same.
For both companies and individuals, having this type of protection will help us alert ourselves to the presence of any danger, as well asact as evidence in case you have to report the facts to the police.
However, cameras have their own limitations. In this case, these are usually related to the image since, depending on the quality of the camera, they will be more or less sharp.
Precisely for this reason, it is advisable to be well informed about night vision cameras, which will solve the problem of surveillance in poorly lit areas.
What is a night vision camera
Night vision cameras are those designed to capture images of a place without lighting. Apart from night surveillance, these devices are essential inblackouts, or for spaces that tend to be dark, such as garages, warehouses, etc.
These cameras capture wavelengths that the human eye cannot perceive, using different types of sensors that are capable of doing so. This makes them the perfect complement even to areas that have security guards.
One of the biggest advantages of the night security camera is that it is not limited to the ability to record low light spaces. Generally,They also record in lighting conditions, and when it disappears they automatically activate their sensors to capture images in the dark.
Regarding the technology to record under these conditions, the truth is that Not all night cameras work the same. , but there are different types depending on the type of sensor they incorporate.
Types of night vision cameras
Capturing images in the dark can be carried out using different types of technology. Here night cameras have a lot to say.
- Thermography: We know that bodies, both animate and inanimate, emit infrared radiation, which can be detected when contrasted with the humidity and temperature of the environment.
- Image intensification: This method does nothing more than amplify the intensity of the light, allowing a specific space to be illuminated and thus capture images of it.
- Active lighting: This is a technology based on emitting infrared radiation through an active lighting source in the mid- or near-infrared band.
Depending on the technology used or the sensors incorporated in the device in question, night security cameras can be classified into three different classes.
Infrared or thermal cameras
These cameras, based on thermography or thermovision, capture the temperature of the different objects and people in a space, reproducing it by color. In this way, the silhouette of the bodies is formed and what is happening can be recorded.
Light amplification cameras
As their name suggests, they amplify the light in space and thus allow you to see what is happening. Your images are clearer and sharper than those of infrared cameras, but they have the disadvantage of being able to dazzle. To avoid this, they turn off when passing a certain threshold.
night crystals
These are lenses that collect and detect light, widely used in objects such as telescopes or binoculars . In essence, they allow a user to see better in the dark, and there are surveillance cameras that incorporate them.
Tips for purchasing a night vision camera
How do you know which night camera is right for you? Before purchasing it, determine well what your needs are, after which you will be able to locate the model that best suits them.
Among the most important factors of this type of device, stands out the scope . To choose a good night camera, it is very important that you take into accountwhat is your range, since this will be variable.
The range directly influences the sharpness with which the images are reproduced, so the best way to decide is to check at what distance the vision begins to worsen. Does this mean that I have to buy the one with the most range? No.
What you have to measure is the distance of the space you need to monitor, and decide on a device that adapts.
Night camera lighting
Most night vision camerasThey incorporate LED illuminators to amplify the light in the space. Be very careful when opting for the most powerful one, since too much lighting can mean a loss of precision when capturing the closest objects. It could dazzle.
On whether to choose an option with LED or one thermovision camera , this depends on the function of the device. Thermal imaging cameras are useful in warehouses and places with high temperatures, since measuring heat will help prevent fires.
However, if the intention is to protect the space especially from theft, it is essential that the image is as clear as possible , for which a light-amplifying camera will be more useful.
Installation of night security cameras
The installation of these cameras is very similar to that of any other type of device, although there are a series of issues that you should remember. The first thing is to check that the camera focus is properly adjusted.
- In a dark environment, it is importantmake sure that the camera is not out of focus, which would considerably worsen the image quality.
- On the other hand, don't forget to make sure that the sensors work correctly. These devices activate their infrared automatically when they detect the absence of light.
- We advise you that, once connected, you leave the room in the dark to check that the camera detects it correctly.and activates its ability to record without lighting.
- Otherwise, check that the height and angle are correct, and connect the camera accordingly, either with the cable or with the Wi-Fi signal.
Do you already have your night security camera? It is time then to finish completing the security of your home.
