Must-Know Factors That Influence the Security Level of CCTV
The type of zoom capability in the camera is one of the criteria that set the stage for maximum security in CCTV camera systems. There are two types of zoom commonly found in modern CCTV cameras: digital and optical zoom. These features have their advantages and disadvantages. In this article, we will focus on the differences between digital and optical zoom with respect to maximum security in CCTV camera systems.
Digital Zoom
Most of the consumer-grade cameras including CLOSE-CIRCUIT TELEVISION or CCTV cameras, have this feature called digital zoom. While digitally zooming in, the camera literally crops the image and enlarges the selected portion digitally, giving the impression that the selected subject is magnified. The disadvantage of digital zoom is that it sacrifices quality for this effect. It really does not enlarge the image but stretches the pixels and makes the picture fuzzy and less sharp and detailed.
Is digital zoom suitable for getting maximum CCTV security?
Digital zoom can indeed be useful in some instances where a slight magnification is needed. However, with regard to surveillance and security, the quality loss that is usually accompanied with digital zoom usage can be a major limitation. In the most dangerous situations that involve clear and detailed images for identification of individuals or objects, digital zoom may not be ideal.
Optical Zoom
Optical zoom is the true form of zoom, taking in everything possible without damaging a photograph. What happens is the physical lens of the camera gets adjusted, and it zooms in and out so closely, without losing its clearness and sharpness, from its view of the subject. It makes optical zoom ideal for those clear and detailed shots required for security needs when observing through CCTV cameras.
Why opt for optical zoom in maximum security CCTV cameras?
Acquisition of such high-quality images, even in-close subjects, without any loss of fidelity or sharpness cannot be of use to deny maximum security in CCTV applications. Therefore, zoom in this area while judging specific regions and objects, and have the sharp image necessary to do proper monitoring and identification. Optical zoom gives an important feature toward maximum security in CCTV camera systems.
Comparison
Thus, from all that has been mentioned, it appears that optical is the only solution to existence maximum security in any CCTV camera system since it yields clear, detailed images without blurring. Digital LEDs offer some sort of illusion of magnification, but that is all it offers-the illusion-of magnification without the detail and clarity borne out of all good things about optical viewing. Such optical zoom must be the priority while selecting a CCTV camera for maximum security applications; because this alone can make the difference in how capable the entire system becomes.
