Video surveillance is everywhere today, from private home installations to massive enterprise deployments. And while the migration from analog to IP has been on the rise for several years, many companies of all sizes and shapes have been hesitant to make the leap to an IP-based video surveillance installation. Using HD  cameras, IP-based systems bring the inherent advantages of network storage to video surveillance as well as the overall storage needs of a business.  IP camera software, also known as network camera software and NVR software, allows you to record surveillance video from IP security cameras to a central computer / server over an IP network.

A Network Video Recorder (NVR) is a video recorder that is connected to your computer network and records video footage from the IP cameras also connected to that network. It allows you to manage an IP camera system via existing computers and IT hardware.

A NVR is different from a network-capable DVR in that a DVR is for use with analogue CCTV cameras that must be physically connected to the DVR itself, whilst a NVR is for use with IP cameras and records video from the cameras via the network without need of a direct connection between the IP cameras and recording device.

IP Cameras – Network IP cameras transmit video over network wiring (cat5/6) just like your typical computer or laptop. These cameras tend to offer a lot more features and come in various HD resolutions that are not matched by its competitors. There are several cameras over 20 Megapixel on the market today. IP cameras offer consumers the ability to program cameras individually and separate from the recorder. This means that you can have IP cameras that are not connected to a recorder at all. You can have an IP camera connected to a network by itself and view the camera independently without the need of a recorder. This is something the other technologies simply cannot do. IP surveillance cameras act much like a recorder themselves by providing full programing of their resolution, bandwidth usage and even email alerts. You have a vast amount of options with IP cameras that you simply will not get with other technologies. The downside is the learning curve for most consumers. Consumers that do not have network experience or will never use these advanced options will opt for a more simplified surveillance system. Another downside to IP cameras is that you cannot transmit further than 330 feet without needing a repeater or booster to further the distance of the IP camera. This can add to your cost if you have long wire runs.

NVR vs DVR – The difference between an NVR and DVR can be confusing to many. A network video recorder (NVR) records IP cameras that are transmitted via a network cable. These cameras connect to an NVR either by way of a network switch or router and in some cases directly to the recorder itself. In essence, NVRs record IP cameras. Digital video recorders (DVRs) are synonymous with recording analog or coax based cameras. Newer HD-SDI or HD-CVI cameras also transmit via coax cable and also use DVRs to record. So in short, a DVR records cameras that are connected via a coax cable. There are more technical details involved explaining the two technologies but for the purpose of this article we will keep it as simple as possible. They both record cameras and offer the same similar options but they record different transmission methods.

Low-definition analog camera systems and DVRs are beginning to reach their end of life. This is largely because of competitively priced, HD -definition IP cameras and NVRs that use advanced hard drives designed for professional use with a backup design commonly known as RAID (redundant array of independent disks). With RAID, data is spread across multiple HDDs. If one drive fails, the files have been backed up on another hard drive.  Additionally, the maintenance expenditures required to support legacy video hardware create an urgency to upgrade equipment.
