"Do IP cameras affect internet speed?" If the network is slowed down, your access could be seriously affected, which could impact various aspects of your day-to-day life, including searching the Web, using your smartphone, and using any other device that may be connected to your network. If you are considering the IP camera bandwidth consumption, and wondering whether IP cameras slow down your network, you can spend a few minutes checking out this article.

Want to know if security cameras will slow down network, here is what you need to notice:
|Slow Down||Yes, but not much|

I was thinking about IP traffic on my home network and wondering if I'd overwhelm it with traffic from my cameras.
IP camera internet usage is one thing that you will certainly consider before installing a security camera. Do WiFi cameras slow down Internet?
In fact, the wireless security camera will NOT slow down the Internet if you are not remotely accessing the cameras via phone, PC or other devices – the impact is so small that could be ignored.
And the technology is always advancing, which means that IP cameras are becoming more adaptable to networks, and thus having less of an impact on them.
For example, the H.265 and H.264 cameras compress the recording files to a smaller size, and the battery powered cameras which use bandwidth only when motion is detected.

"Will 2 to 3 security IP cameras affect internet bandwidth?"
Generally, the IP camera Internet usage, namely the upload bandwidth and download bandwidth your security camera uses, varies due to several factors:
- Compression codecs: It's a major cause of your WiFi security camera data usage. MJPEG/MJPEG-4 and H.264 are the two most popular compression standard in the video surveillance and security industry.
- Camera resolution: A camera that offers higher resolution will require more bandwidth, which requires more storage, and will thus slow down your network. Say, a 5MP camera will definitely need more bandwidth than a 2MP or even 4MP IP security camera does.
- Frame rate (frame per second): The frame rate determines the quality of your CCTV surveillance footage. The more FPS, the better videos. FPS also has an influence on the data of your CCTV streaming uses.
- The number of IP cameras: The more cameras installed in your home, the more data your security system will use.
How much data does a WiFi security camera use exactly?
If you know the 4 variables mentioned above, namely the camera resolution, compression, FPS and camera numbers, you can easily calculate how much bandwidth the security camera uses via the formula below:
Bandwidth (Mbits) = Frame Size (Kb) * 1024 * 8 * FPS * the Number of Cameras / 1000000
If you are having trouble finding all the necessary information required, you may check this post for detailed instructions about IP camera bandwidth calculation.
Editor's Tip: The Internet speed needed for security cameras is around 1Mbps and up to 2.5Mbps for higher resolution videos. So, you can use online tools, such as the IP camera bandwidth calculator, to see the internet speed requirement for your IP cameras to work, and get normal video streaming.
If you are concerned that an IP camera will load down your home network, here's a look at some things that you can do to reduce the amount of bandwidth it will use.
Select the Proper Compression Format
Right off the bat, you should familiarize yourself with the settings of your IP camera and opt for a compression format that will best suit your specific needs.
For example, if you want to increase your storage, an H.264 format may be a good option for you, as this will reduce the amount of storage space your IP camera requires, and will thus save the IP camera Internet usage.
Use the Right Resolution
Another way that you can avoid having an IP camera slow down your network is by choosing a camera that provides the least amount of resolution that you need in order to get the job done. (Click here and follow our senior security expert, Elvia, to see what pixels you'll need if you want to identify license plate and people.)
Of course, you don't want to compromise security when choosing a camera. Before opting for a lower resolution camera, make sure that you take into consideration the area that you are monitoring.
For example, if you are monitoring a larger area, such as a parking lot, higher resolution like 4MP, 5MP and even 4K may be necessary; however, if you are only using the camera to monitor a small space, such as a door or a hallway, opting for a 1080p security camera that will capture the detail you need is a wise idea to avoid unnecessary strain on your network bandwidth.
Lower the Frame Rates
Lowering the number of frames the IP camera catches per second can also help to avoid unnecessary strain on your network, which will help to avoid slowing it down.
While it may be nice to capture a high amount of frames per second, doing so will have a major impact on the speed of your network.
Generally speaking, capturing 15 frames per second is more than enough to effectively monitor your home and will show you everything you need in order to capture evidence of criminal activity.
Choose Motion Detection Cameras
Does an IP camera use bandwidth all the time?
Some security cameras, usually the battery powered ones, only wake up when motion is detected, and thus they will not use the network all the time, saving your home bandwidth.
Watching security camera live stream frequently when nothing is occurring will definitely slow down your network.
So, a motion-triggered security camera, which only kicks in when it detects motion, will be a better choice. Such surveillance cameras can reduce the amount of data and storage used and won't lag your connection to the Internet at all.
However, setting your camera to motion detection mode could be a little different. The cameras will still stream videos and use bandwidth all the time, and that's why they can do pre-recording.
Isolate All Cameras on Separate Network
If the above methods fail to deal with the laggy IP camera network, separating WiFi network for cameras can be a reassuring way.
You can use a two-router system to take all of the traffic from the wireless IP cams off the main router and isolate them to the secondary router. Then have the server, PC for example, be connected to the secondary router for recording and remote access. And keep all of the gaming and network systems connected to the main router.
Or you may purchase an unmanaged gigabit switch which will provide very good separation between the camera traffic to the recording PC and the rest of the network.
Set up Security Camera Systems
A security camera system will not slow down your network – actually it will have zero impact on your home network – as long as you don't need remote viewing.
That's because the Internet cameras and NVR recorder will automatically set up its proprietary network and start to communicate with each other without connecting to your router and slowing down the network.

Want remote viewing and push notifications to your phone but the network connection is weak around the installation spot? You can perfectly handle that with a 4G cellular security camera.
