It has become very common in this modern day and age to invest in CCTV Cameras to record and archive high-quality videos for surveillance and security purposes! Basic components of a fully equipped security system is a CCTV Camera, Storage unit and a computer system for observation purposes. These components are fused into single unit usually referred to as a digital video recorder. That can not only record high-quality videos but also store them. Some of these devices are so advanced that they can be used to record on the basis of the slightest movements because of motion detectors embedded within them!\n\n\n\nSince these digital video recorders are used for surveillance and security purposes, they are specially designed in order to be adaptable to different sizes and be used for different applications based on the user\u2019s needs! Smaller devices can be easily conceivable and may not be easy to find! Some of these devices can also be controlled by remote controls! There are three main types of digital video recorders! Let\u2019s take a look at these types!\n\n\n\nPC-Based DVR\n\n\n\nThese are usually integrated and fused into a fully equipped surveillance system! These consist of software as well as hardware components that are compatible with a personal computer. These usually consist of a video board, network cards as well as memory drives and a motherboard. They also consist of a DVR capture card that has Ethernet ports useful for sending video inputs over a network usually used in IP Cameras. These have huge memory drives and serve no issue when dealing with storage. These storage units are expandable by using additional peripheral devices like external hard drives.\n\n\n\nEmbedded DVR\n\n\n\n These systems usually have only one unit and are useful in recording footage of CCTV Cameras and can store them in memory storage drives and peripheral storage devices. It uses software to run the system as well as to software to store onto the memory devices embedded in the system. These have multiple internal memory units and ports allowing the device the added feature of connecting the device to an external hard drive. It makes use of a real-time operating system that cannot be accessed by external components. This makes the system even more secure and safe from malware and viruses. \n\n\n\nHybrid DVR\n\n\n\nThe unique feature and advantage of such a system is the ability to record different types of video footage formats for both CCTV Cameras footages as well as IP Cameras footage. There is a smooth transition from analog to IP surveillance in such a system. Because of this, it doesn\u2019t have a lot of video recording restrictions. The biggest disadvantage in a hybrid digital video recorder is the inability to be flexible compared to the other types of DVRs. \n\n\n\nConclusion\n\n\n\nAt the end\nof the day, security needs differ from institution to institution especially in\na low crime area like Mangalore. These different requirements must be\ncalculated carefully before deciding which type of DVR to invest in. It is\nhighly recommended to consult with a professional service or to refer to a\nlocal listing service like oyoList before investing in one! So good luck with your\nsurveillance!
