Security of property and people is important for any commercial and industrial business owner. They are investing in various security solutions, such as IP CCTV cameras and NVR systems to achieve this safety and security. IP CCTV cameras have been described and discussed several times over the years; however, Network Video Recorders (NVR) are understated for various reasons. They are used with IP cameras to enhance the effectiveness of security installations. What makes them popular? How to set up NVR for the IP camera on the network? This post discusses everything you wish to know about NVR camera systems
A Network Video Recorder (NVR) is a system featuring a software application. This system is designed to collect and store the videos captured by all cameras connected to the network. NVR records these videos on mass storage devices. Unlike other storage devices, it features no specific video capture hardware, and the software is operated on a dedicated device. NVR is usually employed on the IP video surveillance systems, and they are capable of streaming video/audio data on a single cable.
NVR can be set up with or without a Power over Ethernet (PoE) or Non-PoE switch. PoE switches are used with PoE compatible cameras. The cameras are plugged into the PoE ports of NVR and they require no individual power adapters to function. Non-PoE models feature no ports for plugging for cameras. However, they feature an inbuilt scan function that can scan the camera on the same network. The scan feature is also used by PoE models.
For configuring, the NVR for IP camera on the network using PoE switch, you will require some components and accessories including a power cable, an Ethernet cable, SATA cables, security screw, and a power supply cable for hard drive installation. Most manufacturers provide technical assistance during the connection process or they also supply an easy-to-understand instruction manual with the product and accessories.
NVR is very much similar to digital video recorders (DVR). DVR is mainly used with analog cameras, whereas NVR is used with IP Cameras. It is basically a DVR of an IP camera.
you can find ethernet switches for IP surveillance in different configurations. The configuration starts with a hardware setup. Here is how you can proceed with the hardware setup:
When these steps are performed properly then NVR and IP camera connection can be easily made. Software setup is the next step in the configuration, and this can be easily done by following the instruction manual provided by the manufacturer.
As discussed before, NVR without PoE switch has no Ethernet ports at its back panel. It utilizes an external power adapter or an external PoE switch to power each IP camera. Like NVR with a PoE switch, the configuration of NVR for IP camera without a POE switch also begins with the hardware configuration. Here is how to proceed:
Recording will be enabled only when users add the cameras to NVR. This can be easily done by referring to the steps in the instruction manual.
Here is everything you may want to know about the configuration of NVR with IP Camera:
NVR when connected to the Internet provides easy remote access of the recordings. It sends alerts or notifications to users regularly and creates backup of the videos on cloud storage solutions. In the absence of the Internet, NVR will record and stream the videos, but they will not be remotely accessible to users.
The maximum transmission distance of the Ethernet cable connecting the NVR and an IP camera is 100 meters. This distance limited due to the attenuation of signals. The Ethernet extender is used to extend the transmission distance beyond 100 meters.
No, you can use NVR without Internet, too. Most NVRs can be operated as CCTV systems in the absence of the Internet. However, the absence of Internet makes it difficult to view the captured footage off-site.
No, IP CCTV cameras do not always need NVR. Many IP CCTV cameras have SD card slots, allowing users to record and store videos.
Yes, you can add more cameras to NVR. If you are using an 8-channel NVR, you can add more cameras to it without buying a new NVR. Depending on your expansion plans, you can buy NVR with 4, 8, 16, 32, 64, and 128 channels.
All the above pointers will help improve your understanding on NVR systems, but that is not enough. You must address several factors while selecting NVR security systems for your applications. First, you need to check the compatibility of NVR security systems with the IP cameras on the network. Next, you need to ensure the NVR camera system supports the camera resolutions because many cannot support 12MP or 4K security cameras. After all these considerations, ensure to use quality PoE switches for the connection. VERSITRON provides PoE media converters and switches in different configurations. PoE switches are one of the most popular products in their collection. You can contact the company’s experts to discuss your requirements for PoE switches for IP CCTV cameras and NVR systems. Versitron provides PoE media converters and switches in different configurations.
