Considerations for Infrastructure
Compound annual growth expected to continue through 2023

ecurity is top of mind for consumers around the world and businesses across industries. This is evident in the booming video surveillance market. Markets and Markets estimates the video surveillance mar- ket, including both analog and IP video surveillance
systems, will grow from $36.89 billion in 2018 to $68.34 billion by 2023, with a compound annual growth rate (CAGR) of 13.1 percent between 2018 and 2023. The market for IP video surveillance systems is expected to grow at an even higher CAGR. IDC expects there will be 41.6 billion connected IoT devices, or “things,” generating 79.4 zettabytes (ZB) of data in 2025, with most of that data being gener- ated by video surveillance applications.
What is causing this explosion in IP video surveillance, in addition to concern for public safety, is largely the swing to IP systems from traditional analog systems. Using IP cameras and NVRs instead of DVRs replaces separate cable connections to each camera with Eth- ernet networks that connect multiple cameras to the recorder.
There are several benefits to deploying IP surveillance systems over analog systems as you plan your infrastructure from endpoints through edge to core.
Easy to Install, Easy to Expand
In the past, most surveillance cameras were connected by one discrete

cable. Gone are the days when a recorder with 16 cameras would re- quire 16 separate cables. Leveraging an IP connection over a network, all you need now is one ethernet cable for each camera to connect to. No matter the size of the company, from a mom-and-pop shop with a few cameras to a commercial bank with 100-plus cameras, surveil- lance cameras at endpoints can connect to the secured network and then to a centralized recorder and server.
With traditional analog cameras, adding cameras would mean adding more recorders and more cables for each one. In an IP world, you can support additional cameras simply by registering each ad- ditional camera to the network using its IP address. In home security, if you want to add a camera to your front porch, you can just hook it up to Wi-Fi, assign an IP address, and the camera starts pinging the network while the recorder constantly pings for new connections.
ONVIF Enables IP Conversations
ONVIF (Open Network Video Interface Forum) is the open standard protocol that allows IP cameras to communicate and link with other surveillance components, including network recorders. As new cam- eras are added to a network, the recorder can negotiate and recognize the cameras and begin recording video streams.
ONVIF also allows common camera parameters such as resolu- tion and frame rate to be set by the recorder. System administrators
