Before opting for a video surveillance technology, customers need to have a clear idea about what they need to accomplish. Performing full site survey and determining the number of video recording devices required are important stages to make a well-informed selection. Often the vendors of surveillance recording devices help customers in understanding their requirements well, and accordingly make the right buying decision.
The surveillance recording technology is on the upswing. Ordinary cameras have been replaced by high-resolution cameras, which provide clear and high-definition images and videos. For an effective surveillance, it is important to determine the right camera and video recorder. Owing to the advancement in video recording technology, various options are available in the market for buyers.
VMS is a software-based solution that is deployed on servers. It enables users to view, manage and record IP surveillance video from different security cameras, access control systems and hardware, at the same time. VMS is highly scalable and enables recorder control, live viewing, and system management. A single, easy-to-use graphical user interface is used to record videos using VMS. Video management system can be scaled up to hundreds of recorders and encoders and thousands of cameras deployed in a field. It is widely used for unifying large, networked video systems with a simplified central operation.
NVR is available with different channels of concurrent HD that helps in better recording. While both VMS and NVR record video, NVR is widely used for recording video while a VMS is put into the task of managing video along with recording. It is extremely useful for streamlining complicated functions like integrating with complicated enterprise networks and managing bandwidth. NVR rarely requires additional licensing requirement, and thus it saves costs.
NVRs are currently available with 128 channels of concurrent HD or better recording. While both record video, a NVR’s sole purpose is to record video while a VMS is tasked with the purpose of not just recording, but also managing video. Generally speaking, this holds true, especially for more complicated functions like managing bandwidth and integrating with particularly complicated enterprise networks. NVR systems, however, rarely require additional licensing costs. Other significant tasks like I/O triggering, motion detection, and managing remote view access are performed by NVR. Another important factor to consider is that NVRs come with simpler operating architecture. This recording device also features cutting-edge compression applications and algorithms.
VMS vs. NVR
Hardware-based network video recorder (NVR) and software-based video management system (VMS) are used by enterprises to capture and store images. Both these options are equally useful for video recording. Depending on which one of these two would be ideal for a particular application, you can make the final selection. NVR and VMS are well-suited for large, multi-site installations with multiple recorder. The only way you can decide between NVR and VMS is the number of cameras required for your project. If appliance type recording device is limited to 16 or fewer cameras, NVR is an ideal choice. However, VMS setups are being used for single camera recording.
Choosing the Right Security Cameras
Along with video recording devices, the choice of security cameras should also be based on your requirement. Different types of security cameras available in the market are fixed camera, PTZ camera and 360-degree camera.
Fixed camera is used to capture an image by always pointing towards the intended direction. This camera type can be optimized for specific applications with the use of different housings and advanced features.
Users can pan, tilt and zoom PTZ cameras on a particular subject to follow a person or object across a particular area. It is a form of fixed camera, which is wrapped in motors and gears. It is widely used to patrol an area, and is often manually controlled.
360-degree camera constitutes several high-resolution, fixed cameras placed together on a single housing. With the use of different cameras, images are recorded and stitched together for the surveillance of a wider area. Users can also zoom in the images for more clarity.
Although many surveillance systems are easy to install, it is always a better idea to take the help of experts. Surveillance system vendors, who hold ample experience in setting up the system can consult you in making the right choice for surveillance recording.
