Features of Choosing a Video Surveillance System

Security video surveillance systems have become the most common and effective method of protecting any facility from unlawful actions.

Today, manufacturers offer both analog and digital video surveillance systems. However, facts show that digital video surveillance systems are becoming the most popular among consumers. Factors contributing to the high demand for digital systems include: the latest technologies that provide higher image quality, high data transfer speed, as well as the ability to display the time, date, and camera number on the recording. The system also allows zooming in on the image both during recording and after archiving. A clear advantage of these systems is the possibility of remote monitoring. Internet access enables not only remote observation but also receiving warning messages by e-mail. Recording can be done on various removable media, while the system itself requires relatively low maintenance costs.

Of course, analog video surveillance also has some advantages, though fewer – mainly its simplicity of installation and use.

If the plan is not to limit yourself to a single camera with mediocre image quality, it is better to choose a system based on a digital video recorder (DVR) or an IP server. These devices not only ensure high-quality recording but also allow connecting multiple cameras and continuous 24/7 recording.

Due to the widespread use of different systems, video surveillance installation services are now in high demand. At the same time, IP video surveillance is becoming increasingly popular. This technology enables wireless digital monitoring via Wi-Fi and offers many other important advantages. Once you decide on the system, you should also carefully consider which video recorder to purchase and which type of camera to choose, since recording quality directly depends on them.

There are two main types of cameras most commonly used in digital video surveillance: IP cameras and analog cameras. The market offers a wide range of models, but the most popular options include:

• Pan-tilt cameras – covering a large area thanks to adjustable viewing angles; among them, high-speed PTZ cameras with motion detectors are especially effective.
• Day-night cameras – advanced devices that provide quality monitoring at any time of day without image loss.
• Infrared (IR) cameras – the best choice for night surveillance in complete darkness.
• Hidden cameras – allowing discreet monitoring when required.
