Security cameras have been the first choice when it comes to enhancing the safety of a place. You need to choose the right surveillance camera from the innumerable options (Analog camera, NVR, DVR, HVR to name a few) depending on your needs. . One thing that you need to be careful about is that the firmware of the cameras needs to be updated on a regular basis even after it is installed. All good manufacturers release malware updates, like Hikvision camera malware updates and by updating your firmware you will be completely secured.
The two greatly popular kinds of surveillance systems are Network Video Recorder (NVR) and Hybrid Video Recorder (HVR). As the name suggests, both are meant to record videos from the security cameras with some differences. The consumers might get confused as to which they should buy, but the following explanation should help them in making the right choice.
Network Video Recorder (NVR)
This security protocol is paired with IP/network security cameras, which record the video footage in a digital format to any mass storage device. This can be an HDD (Hard Disk Drive), a USB flash drive or a memory card. There are two types of NVRs that are commonly used, but both can be used with IP cameras. The first type needs you to connect the IP camera to the router or switch, while the second type has a built-in network or power over Ethernet (PoE) ports. Thus, the need for manually adding the camera to the NVR device list in the first type gets eradicated in the second.
An NVR built with sufficient memory, processing power and storage can support a number of installed cameras. At times, just by adding a little more RAM and storage space, more cameras can be supported by the same system. The resolution in this is much better, which helps in providing greater details of a limited area or the coverage area can go up with slightly limited detailing.
Hybrid Video Recorder (HVR)
This recorder, when introduced, quickly started becoming popular, the reason being its versatility. These recorders are compatible with both the digital as well as standard analog signals and hence the name hybrid. So, you have the flexibility to connect IP cameras or AHD / CVI/ TVI/ Analog channels and everything works perfectly.
This option suits perfectly if someone is planning for a future expansion moving from analog to IP video surveillance. The transition in such cases can happen seamlessly by using the existing analog cameras and incorporating them into the new system without getting any drop in the coverage.
Now that you know about both the systems you can decide which suits your needs the best.
