Everything You Need to Know About Night Vision CCTV Cameras
Home security has become a serious problem over the past few years. A sharp increase in burglaries around this period has made property security a global concern. An estimated 50% of burglaries in the United States alone are home invasions, emphasizing the need for more effective security systems.
Fortunately, innovations in modern security systems have made protecting your family cheaper and more effective. A shortlist of these new technologies includes motion sensors, infrared, and night vision CCTV cameras.
Night vision capabilities have been around since 1939, but it wasn't until 1943 that this technology became useful in low-visible circles. Fast forward to the 1980s night vision when third-generation night vision equipment, or what we now refer to as the auto-gating function, was able to penetrate consumer markets and special operations programs.
How Do Night Vision CCTV Cameras Work?
Night vision cameras use thermal imaging and infrared technology to produce clear images in low light. This feature allows them to tap into atmospheric temperature and warm body imaging to identify trespassers and burglars on your property.
In 2022, night vision counts as sophisticated equipment used for military and security purposes.
Night vision also uses a system that emits non-toxic infrared radiation to produce images that are invisible to the naked eye. Modern night vision cameras have adaptive infrared illumination, high light sensitivity, and an ICR filter for added clarity.
Light sensitivity is one of the standout features of this security camera and has the rare ability to produce crisp imaging on a moonless night. In principle, even in the absence of natural or artificial lighting, a night vision camera can present an excellent picture. The primary reason many security cameras have night vision technology is to enable you to see in pitch darkness with little effort.
Another standout feature of this technology is it can intensify existing light and amplify it for better image clarity.
Night Vision CCTV Camera Capabilities
As mentioned earlier, this technology is feature-rich. These capabilities work together to give you the value of precision in low light. Some of these primary features include:
Thermal Imaging
A feature frequently used in military circles to identify enemies through heat signatures is termed thermal imaging. Essentially, this technology converts heat energy into visible light. Living things emit heat-this makes them visible to thermal imaging equipment.
Your body heat produces infrared radiation, and in thermal devices, this radiation transmits, is absorbed, or even transmitted. Thermal cameras can capture this heat signature and precisely determine its source.
A thermal imaging system locates burglars via a heat signature. This component makes it easier for you to see an intruder hiding in total darkness.
Low-Light Vision
Modern night vision cameras come equipped with low-light capabilities. These cameras can pull in ambient lighting to illuminate faintly lit areas. This feature is critical because the biggest challenge in monitoring systems is inadequate lighting.
Low-light capabilities improve detail and produce intelligible images at close to zero visibility. Modern night vision CCTV cameras have better pixel sizes, higher sensitivity, and a larger lens aperture. Image sensors in these cameras convert photon energy into electrical signals, producing clear images in areas with insufficient lighting.
For home security systems, night vision helps to produce better detail and image quality in real time. If a perp breaks into your home, a night vision camera can record footage of the burglary and give law enforcement agents more to go on.
Motion Detection
Motion detection cameras use passive infrared to detect body heat and pinpoint warm body locations. This system monitors ambient infrared levels and triggers an alarm as soon as these levels change. A slight increase in heat vision CCTV alerts these infrared cameras, and it is one of the few systems that is difficult to evade.
While effective, night vision cameras equipped with motion detectors can be problematic, especially if you have pets or domestic animals. For this reason, they are not highly recommended in areas with high levels of activity as they may cause several false alarms.
Importance of Night Vision CCTV Cameras in Surveillance System
Modern night vision cameras do more than improve visibility in low-light innovations filter areas. This high-tech equipment helps identify offenders in the dark and is programmed to work without electricity. Motion and infrared detection in these cameras make it impossible for burglars to hide, even in poorly lit areas.
Lastly, the footage from a night vision camera is admissible in court, making a home dark invader night vision system identifiable with this data as the only source of evidence.
Verdict
90% of break-ins happen in the dark-this makes garden variety CCTV inadequate. With night vision cameras, you will be able to secure your home and deter criminals from threatening your property.
