Technology that accompanies surveillance cameras
At first surveillance cameras or whatever was used for surveillance and observing the environment, the main purpose was for security. In recent decades the cameras mentioned above have expanded their use not just as “surveillance” tools but surveillance for purposes other than security.
Until now, security purposes still occupy the top position in the use of this surveillance camera. Better known as CCTV (Close Circuit Television) is widely installed in private homes, housing complexes, office buildings, public facilities, highways, government agencies, and military agencies. The location of this camera placement can be installed outdoors or indoors.
Commercial-Grade Security Cameras vs. Consumer-grade.
The sale of surveillance cameras that are widely offered is Consumer-grade because of the wide range of enthusiasts and users besides that the prices are affordable. The package offers consumer-grade types consisting of 6 to 16 cameras equipped with video recorder capabilities.
Meanwhile, a commercial grade is set at a higher price, because its capabilities are superior to those of consumer grade. The advantages of commercial grade include greater data storage capabilities than a greater number of camera connections and also feature image processing or the ability to process image data.
Commercial-grade design and built to produce high-level capabilities and is claimed to be fail-safe, and can operate in a variety of varying lighting levels.
In general, consumer-grade CCTV can only work properly if the area around the camera range has enough light.
This is not the case with commercial-grade CCTV cameras that have the ability to work more precisely, this is because commercial-grade devices are equipped with internal video sensors.
Commercial-grade cameras have the ability to adapt and work in minimalist lighting, this is because of the internal video sensor. This device is also equipped with software and hardware called HDR (High Dynamic Range) which allows the camera to adapt quickly to changes in lighting.
Even though consumer-grade CCTV cameras can actually work in insufficient lighting, the resulting image quality is less clear.
This is due to the device taking time to adapt to the light, with extra light being let into the room by opening the shutter to compensate.
In addition to the built-in video sensor and HDR software/hardware, this commercial grade is also equipped with an “intelligent IR” (infrared) night vision illuminator that has the ability to adjust exposure. With smart IR this device can record objects in more detail even in low light or dark conditions.
The development of internet technology has brought new changes to the security system which was previously carried out by CCTV independently. Advances in technology have changed the game, the problem of previous CCTV owners was that the data storage devices were damaged for some reason or lost due to theft. Damage to or loss of data recorders leads to evidence of wrongdoing or crime without proof. Without evidence, it is impossible to catch or imprison the perpetrators of crimes.
However, technology has overcome this problem by developing a system called the “Intelligent Security System”, this system works by connecting all security systems including CCTV camera devices to the internet network.
With this system, all data captured by the attached camera is sent directly to and stored in “cloud storage” as data backup storage.
So far, the Intelligent Security System mode is considered the safest and most efficient because apart from cloud storage being separate from the main CCTV device, the cloud also has the ability to store unlimited data.
