Bandwidth usage depends mainly on video compression, image quality, scene complexity, video resolution, frame rate (FPS), and the number of cameras and display clients. Yes, you should also check your download speed. 1.0 – 2.0 Mbps should suffice. So, while you only view your cameras through the app once in a while, if they`re constantly communicating with the cloud, you can easily download hundreds of GB of data per month. For example, a single Nest Cam IQ can use between 100 and 400 GB of bandwidth per month. They didn`t talk too much about download speeds. My ISP told me it was more important than download speed. My download speed is barely one, but the download speed is 18, I can`t go higher. I have two wireless carriers just for motion detection. Sometimes they understand the movement immediately and sometimes I can stand in front of you and wave my arms, do nothing. The camera company helped me everything they know, which was very little. Could you enlighten us on that? And I don`t know how to determine bandwidth or how to determine it. Thank you very much.
The average bandwidth consumption of an IP cloud camera is 1-2 Mbps (assuming 1080p with H.264 codec at 6-10fps). A hybrid cloud camera reaches an average fraction of this figure and is between 5 and 50 kbps in steady state. For best performance with H.265 encoding, you must have a download of 2 Mbps for each 1080P 30 FPS camera or 4 Mbps for each 4K 20 FPS camera main stream. Here is a graph with various recommended bitrate graphs for different IP camera resolutions, frame rates, and encoding levels. And don`t think this issue is only relevant for streaming outside the home, like checking your doorbell camera when you`re at work. Since most large cloud-based systems like Nest and Ring stream to the cloud and then to your home, download speed is important, even when you`re at home with the cameras. A slow download will affect your experience, wherever you are. QEI Security & Technology recommends using speedtest.net to test your Internet speed monthly. If you have problems, test weekly. And be sure to test during peak hours (5-9pm). The Speedtest by Ookla app makes it easy to test your wireless internet speeds and record your history.
But before you buy a bunch of sophisticated smart security cameras with all the bells and whistles, it`s important to ask yourself if your home internet connection can support them properly. Tip: If you opt for a multi-camera setup, it`s a good idea to add each camera individually. This gives you instant feedback on actual bandwidth usage. You can then adjust each of the camera settings to optimize the network as it is assembled. Great article, but even though you`ve written a lot about why and how wireless cameras work, I still have an important question. I live in a rural area and my download speed barely reaches .5, let alone 2 lol. Therefore, I cannot use this type of camera. Please tell me what kind of camera I can use then. I would really appreciate it.
You need to consider all of the above when calculating the bandwidth requirements of an IP camera system. Keep in mind that you need to consider these points when planning your local network, even if you save locally. However, if you don`t plan to use as many cameras and not record high-resolution video, your bandwidth requirements will be more minimal. I intend to change a new Wi-Fi router at higher speeds. I would like to know if the security camera could respond to the high-speed router? Please note that the speed requirements are per camera, because if multiple cameras broadcast at the same time, the speed requirements add up. During an alarm, for example, all cameras record footage. Each NVR has a total incoming network bandwidth that defines how much data it can handle. Different models can be very different in this area, but the overall load is one of the key factors that you need to understand and consider before choosing a video camera security system. Here`s a closer look at bandwidth reduction strategies: (1) the use of “steady-state” cameras; (2) multiplexing; (3) the ability to view live recordings on the local area network (LAN). Hi Dave, yes very good point. Of course, you need a good download speed to view the images.
