What Type of Surveillance System Should People Buy?
Today, the home surveillance market represents a huge amount of motion sensor technology. Various principles of discovery, with its advantages and disadvantages, are listed in this article. Of course, motion sensor manufacturers have sought to reduce defects to zero. Here are some general descriptions of motion sensor types. Keep in mind that some systems tend to require additional sensors to connect an external device, which provides a more reliable level of detection. Passive infrared motion detector PIM sensors can detect a temperature difference between a moving object and the background. Optics can focus on and pinpoint problem areas too. When setting narrow or wide volumetric detection fields, it is necessary to install the sensor in a specific area under protection. This technology does not rely on the camera’s image quality or the illumination of the area. False alarms can be reduced by using various techniques. Meanwhile, if the temperature of the moving object and the environment are the same, the sensor cannot detect movement. In addition, a sudden change in temperature can also prompt a false alarm. It is noteworthy to realize that the PIR detector can be easily installed and adjusted. The price range for these sensors is among the most reasonable. Market leaders that provide video surveillance equipment will also offer a certain number of motion sensors, as a means to get the client underway. For external use, video surveillance cameras must be placed within a certain range of the motion sensor, especially if they want reliable object recognition. Photoelectric sensors Infrared (IR) light source generates a pulsed infrared beam, which transmits a signal to the IR receiver. The transmitter and receiver must be mounted on opposite sides of each other. The receiver detects when the pulsed beam is physically interrupted and then generates an alarm. Photoelectric sensors are designed to create IR rays so that there is a certain “line of defense”. Only an intruder passing through the security line can cause an alarm. The downside is that, if the object is moving too quickly, it may go unnoticed. Furthermore, plant height may block the beam’s path, thus leading to a false alarm. Laser scanning sensors Scanning sensors use specific technology in order to accurately calculate the distance between the subject and the detector module. The scanning mechanism rotates very quickly, making it easy to recognize the size of the object, the distance of motion and its speed. Because of this, it can detect both human and other types of figures. After an image is caught, the system sends the data back to the camera and then the system. Keep in mind that the detection area will be funnel-shaped. Depending on the manufacturer, some products can create highly accurate detection areas, while the exact detection zone parameters and reliable operation is a big advantage for most businesses. However, the price range can be much higher than other detectors. Just fog, heavy rain, and snow may affect the process of detection. Data protection Nowadays, business managers increasingly have to turn to video surveillance systems that will help improve the analysis of business data. It should also improve employee productivity, and most importantly, protect yourself from problems such as theft and fraud. Since the new system continues to receive and analyze all different types of video streams, there are risks and responsibilities associated with the access and control of this type of data. This makes it even more important to pay maximum attention to the protection of information. For security professionals, themselves, it is important to protect video data and prevent the possibility of theft. This is particularly vital for industries that process personal data, such as hospitals or government facilities. For example, a hospital should pay particular attention to its internal data security to ensure the confidentiality of each patient. Large enterprises are subject to the same data leakage and must be protected from fraud, theft, eavesdropping and other security threats. People should choose the device they want, study it in detail, and determine the possibility of protecting their data efficiently. Fiber optic sensors Fiber optic sensors are used for the detection of certain signals. Trapped motion, vibration, pressure from the attacker – all can cause a slight change in the fiber. This, in turn, will send a signal to a detection circuit that evaluates the change, thus creating an alarm. In comparison with other types of sensors, fiber optic sensors have the following advantages: they are composed of electrically non-conductive materials, which allows them to be used in areas with high voltage, mainly because they are not susceptible to electromagnetic interference (EMI) and radio frequency interference (RFI). The market The CCTV market continues to monitor the transitional process from analog CCTV to a more sophisticated IP network of cameras. IP video cameras use network-based video management software, which can effectively collect, manage, and distribute large volumes of video over networks. However, a massive problem with this type of home surveillance is the heavy network traffic involved. High-quality video requires broadband channels. Without addressing this factor, owners cannot obtain proper quality videos. When using external motion sensors that do not rely on the image quality, the number of false alarms can be reduced even in very bright or dark light. The sensors can be installed in protected areas, where they will be clearly visible to the protected zone. The high degree of detection may reduce the number of false alarms, which will contribute to more effective surveillance applications, including local and remote video surveillance.
