With the increasing burglaries and crime in many areas, especially at night, infrared security cameras come to the rescue. With this new technology, many store owners and homeowners can now sleep sound at night.
These cameras are now widely utilized to monitor a specific area. In fact, most large stores and business infrastructures rely on these devices for the safety of their properties and valuables.
With infrared security cameras, the workload of security personnel is also greatly reduced since they can now check the different areas of a building through monitors simultaneously.
So what really are these infrared security cameras and how do they function? These cameras are equipped with infrared LED (light-emitting diode) or the light from another region in the electromagnetic spectrum.
This LED is installed outside the camera’s lens. Furthermore, the LED in these security cameras is considered as a semiconductor light source. Aside from security cameras, LEDs are also utilized as indicator lamps in many devices, and are increasingly used as well as for lighting.
Now, what makes these infrared security cameras useful at night? The lighting produced by these cameras allow the cameras to capture images with satisfactory results even if there is no available light, so even the slightest activity in dark areas are visible to the monitors.
Through some amount of light, also known as low light, the infrared camera can definitely take a picture which seems to be taken during the daytime. Infrared security cameras are therefore used by individuals who have businesses that do not operate at night, and would thus employ maximum security measures to avoid crimes.
Take note, even during night time, there will still be a considerable amount of light coming from the stars, moon, and even from the street lights.
Such type of cameras is henceforth known too as “Night Vision” cameras since they have the ability to capture images during the night. But then, do not be mistaken with such cameras and take them similarly like Night/Day cameras as the latter type of cameras does not have built-in infrared lights.
Another good feature of infrared security cameras is that they are able to capture colored pictures when there is a good quality of light and when darkness lurks in, the camera will automatically turn in to the infrared mode and will illuminate the built-in infrared LEDs.
Infrared cameras are only able to capture images that are black and white when in infrared mode and the light’s level that is required in order to capture a great picture is known as the lux of the camera.
Now, if you have a lower lux, your camera can have a greater ability to view using low light. For instance, 0.003 lux is indeed better as compared to one that has 0.2 lux. Nevertheless, if you are wondering how much lux infrared cameras have, well, they have 0.0 lux, meaning, they can actually ‘see’ even without light.
Meanwhile, with the use of illuminators, regular cameras can become infrared cameras since the illuminator lights the area under surveillance with infrared light so that that any regular camera can record black and white images with the use of infrared radiation, which the naked eye cannot see usually.
Further, these infrared cameras are also available in a CCTV camera system and it is a good move to consider a CCTV infrared camera in order to get a high level of nighttime security and safety.
Lastly, infrared cameras can be customized depending on the needs and specifications of clients. With this, big businesses would opt for a more complex system of infrared cameras for the surveillance of their buildings and to ensure the security and safety of their properties.
