How Does a Security Camera Work at Night with Little or No Light?

The high tech security cameras that are used these days are exemplary instances of platforms that use a striking combination of technology to get the desired results. One of the most crucial questions that may cross people’s minds is how these state of the art devices work at night, when there is hardly any light to ‘see’? Let us take a sneak peek into the issue. 

Infrared Technology

The cameras that are meant to work 24x7 and are supposed to ‘see’ regardless of the light condition use infrared technology or infrared light. It is a particular type of electromagnetic radiation, which is invisible to human eyes. It is essentially speaking, an energy, which emanates from the body of each and every object in this planet. Thus, with the help of the infrared technology, the IR cameras would detect this energy and transform that energy into an electronic signal that is then processed for the production of the image. 

Every IR security camera available in Wollongong comes up with infrared light emitting diodes (LED), which are strategically fitted on the exterior of these cameras, around their lens. These LEDs act as spotlights, to illuminate the images that are supposed to be captured by the cameras. The more is the number of LEDs in a camera, the further it can ‘see’.

External Lighting

There is another way of making sure that your camera is able to ‘see’ in darkness. That is, by using motion detector lights. These motion detector lights are able to detect infrared waves from the moving objects. As and when the motion detector senses any object moving across its line of sight or the field of view, it will electronically turn the lights on. This will allow the security camera to ‘see’ what is going on. 

There are various types of motion detector lights that are used by modern cameras. They can include floor lights and other decorative lights. Floodlights generally have a field view of up to as much as 240 degrees. And they can cover a distance of up to 70 feet or even more than that. Decorative motion detectors lights include those that are fitted on and around the decks and patios, stairways and the pool areas. 

There are a number of high quality security cameras available in Shellharbour that use various kinds of cutting edge technology that helps them to work flawlessly at night in low-light condition. These cameras are known as day-night cameras. These cameras have image intensifiers embedded in them, and these intensifiers are designed to intensify the light that is available. However, unlike the infrared cameras, these cams do not come with infrared LED lights to generate any additional light. That is why these cameras need a minimum amount of ambient light to operate perfectly.

All said and done, the modern security cameras are developed to work in diverse lighting conditions for protecting a public, private or commercial property. Hence, the efficacy of the modern security cameras depends upon how smartly they can adapt to the changes in lighting conditions. This is the most important parameter to be looked for, before you select one.
