Misconceptions Commonly Linked With Low Light Surveillance
May 20th, 2021
In some situations, normal security cameras in , cannot capture a clear and sharp footage. For instance, a security camera that requires a well-lit environment cannot be effective when recording outside a building at night. In normal situations, the outside area under surveillance is not properly lit; an intruder can stroll along with the camera not capturing clear evidence as required by the court of law upon filing a case. This is where low light and infrared security cameras are important. However, it is important that we understand some common misconceptions that surround this technology. They include:
Thermal cameras versus Low Light Cameras.
Night vision cameras come in different types, and differ in terms of functionality. FLIR cameras and thermal imaging cameras are quite different from the typical low light cameras. Most types of low light cameras have IR cut filters that allow the security cameras to operate during the day and night. Thermal cameras usually display images that are related to heat differences in a particular recording. Thermal cameras are, however, not so effective in identifying crooks as they only show heat differences. This implies that low light cameras are more useful in most situations in , .
There are many technologies related misconceptions about Low light security cameras. One of the common misconceptions is that low light facial cameras provide clear facial images. As depicted in most crime scenes, police identify criminals through night version cameras. Getting a similar, high-quality image in real life requires you to understand some photography concepts and meet some criteria such as the amount of light in the image and camera distance.
Low light cameras produce clear images by considering distance which is the main factor. For instance, if you have a security camera that monitors a 100-yard space at the widest setting, chances are that you will not get a clear facial image except when the criminal is at a position twenty yards from your camera. However, the quality of images also depends on the environment in , where the security camera is placed.
Low Light or No Light at all?
As mentioned above, the recording quality is highly linked to the amount of light in the security camera image. Security cameras designed for use at night have a concept that sounds counter intuitive. However, it is important to note that very few instances allow positioning the security camera in complete darkness. There are many forms of ambient light; some security cameras have some kind of lighting on. In a case that you set up a low light camera outside, they will receive light from various sources such as moon and stars. This way, the security camera will produce better images.
Although low light security cameras are not a totally efficient method for maintaining security in , , low light security cameras are helpful in providing important evidence and critical information for individuals and businesses. When monitoring a normally well-lit environment, look for a different type of security cameras that fits a specific environment. One key concept to remember is that the quality of images and recordings depends on the amount of light allowed.
