When the time comes to install a security camera solution, some choices need to be made. Irrespective of choice, all the available systems have the same function (for the most part to provide added security by use of video), but they differ markedly in how they work. It’s thus vital to understand the differences between them to make an informed decision.<\/p>\n
On the one hand, there are NVR systems that are completely digital and on the other, there are DVR systems that use analog signals in recording and storing video.<\/p>\n
The problem is that there’s so much information out there that it may be difficult to filter the good from the bad. Luckily, this post will deal with these systems in more detail and give some advice on which is best for a particular purpose.<\/p>\n
The first contender is the NVR, or the new kid on the block that relies on newer technology that offers several benefits over DVR cameras.<\/p>\n
An NVR<\/a> or Network Video Recorder records video directly from the network using either Cat5 or Cat6 Ethernet cables. IP cameras<\/a> encode video and send the data through these cables to NVR for storage.<\/p>\n An important distinction with the NVR is that it doesn’t process video. The cameras do all the processing, and only the data is sent to the NVR where it can be stored and viewed.<\/p>\n Well, here the NVR has two options. The most common option is for IP Cameras to connect to the NVR with the mentioned Ethernet<\/a> cables with RJ45 connectors. Here, NVRs offer an added benefit in that it supports POE or Power over Ethernet that allows the use of the system with fewer cables if the camera supports it.<\/p>\n One drawback with Ethernet cabling, though, is that they can only run up to about 300 feet before any further components are necessary to preserve the data.<\/p>\n Another way option for connection can be to utilize Wi-Fi cameras wirelessly. This obviously has some benefits when it comes to installation, but there may be concerns with stability as Wi-Fi signals are not always 100% reliable.<\/p>\n POE offers the ability to only use one cable for power, video, and audio. This means it’s not necessary for power outlets for each camera and eliminates the need for splitters like with DVR systems.<\/p>\n The Digital Video Recorder or DVR is the older of the two types of recording devices and relies on older analog technology.<\/p>\nHow Cameras Connect to an NVR?<\/h3>\n
