DVR & NVR Video Surveillance Systems
Everything You Need to Know About DVR & NVR Security Camera Systems in Long Island
If you use surveillance camera systems at your business or home and you want to access the footage, utilizing Digital Video Recorders (DVRs) or Network Video Recorders (NVRs) are an excellent option.
A DVR monitoring system is a common way low definition or coaxial video signals are recorded and security footage is stored. It contains a CPU board, various software and firmware and of course a hard drive to archive local data. Digital Video Recorders can take in video feeds and turn them into a digital format of images or video. In addition, they have the ability to hold hours of footage and to apply motion detection and other simple analytics during recording.
DVRs are issued in various sizes (ex.4 channel, 8 channel, 16 channel, 32 channel, etc) and are created to fulfill different security concerns. Most recorders can connect to a remote network, allowing you to watch footage on the internet from anywhere in the world.
Different Types of DVR Surveillance Systems
Hybrid DVRs
Hybrid DVRs are distinct due to the fact that they can accept one or more kinds of video signals, including analog CCTV camera signals or CVBS, as well as CVI, TVI and IP camera components that can be used as video inputs. This degree of flexibility isn’t available from previous versions of DVRs. They grant easy transition from analog surveillance systems to IP-based systems and vice versa.
Because they support both IP and low and high definition analog signals, users do not have to restrict their camera recording prospects. It’s recommended to install analog recording cameras in safer areas before they are typically lower definition video and place high-resolution IP cameras in spaces with a high degree of security vulnerability. The main benefit of employing this kind of recording system is that it allows the possibility of easily managing and recording with either analog and IP surveillance cameras.
Embedded DVRs
This model is a device that is stand alone, accepting various CCTV camera system inputs for compression and storing recordings on a local hard drive. The system and software it operates on are built-in and it has an HDD or hard drive to save recorded information. Embedded DVRs typically have a variety of internal hard-drive reservations and additional external hard-drive attachments for extensive recording times. Embedded systems work well because it eliminates a lot of network vulnerability since the since is considered a closed loop system.
PC-based DVRs
A DVR security system based on a PC is usually integrated into a surveillance situation with hardware compression or software compression operating on a personal computer. This kind of DVR environment contains a video board, a network card, a motherboard and a memory drive, as well as Ethernet ports for IP-based cameras and a DVR capture card for analog cameras.
One of the greatest aspects of PC-based DVRs is the level of adaptability in terms of storage space. They’re more upgradeable and expandable, offering you the capacity to add on more hard disks. You can change its remote-access selections as well.
This DVR security system operates by turning analog data into digital signals that will go on to be compressed and saved on a hard drive for additional processing. This arrangement lets the users search or call up captured recorded videos or images at any point in time. However, PCs have become obsolete in recent years, and are most often replaced by Embedded recorders or full cloud-based video surveillance systems.
Network Video Recorders (NVR) Surveillance Systems
Similar to their brother the DVR, NVRs allow you input surveillance cameras onto a closed loop system. The major difference is the protocol that these systems work at. NVRs are able to read IP cameras only, which means that this camera can be placed on a network without having to be plugged directly into the system. This gives systems the ability to grow very large or matrix in cameras from various sites onto the same recording device. Also, IP cameras are usually capable of a much higher video resolution, making them very attractive to today’s security-minded customers.
All kinds of recorder arrangements are extremely effective but it’s important to establish the correct type that will satisfy your security obligations.
