Bandwidth Requirements for Cloud Based CCTV

When it comes to cloud based CCTV, bandwidth requirements are one of the fundamental elements to consider. As with any other internet reliant technology, understanding bandwidth for cloud based security systems is critical.

Security professionals are often resistant to adopting cloud CCTV, as they’re concerned that the bandwidth requirements of video are too great. For example, what if the site is remote and has no access to fixed broadband? Or, if the site relies on ADSL connection, but has multiple cameras recording simultaneously, will the broadband cope? While it’s true that transmitting video can load the network, it’s not necessarily a show stopper. Furthermore, the opinion that low bandwidth isn’t capable of supporting cloud CCTV is yet another myth. In fact, the reality is often the complete opposite.


Is your internet fast enough to support cloud based CCTV?

When it comes to CCTV, there are a number of factors impacting bandwidth usage. The bandwidth required depends on the number of cameras and the bit rate of the video, which in turn depends upon its resolution, frame rate and the video compression settings of the camera. Videoloft has been tested and optimized for real world networks, meaning it will use as little bandwidth as possible. Should the internet connection completely fail, video is stored on the Videoloft Cloud Adapter until the connection is restored.


Record on motion only

Cloud uses a lot less data than you think, especially if you only save motion events to the cloud. Not only will this reduce bandwidth usage, but also reduce storage usage. By default, Videoloft records on motion, and on average this results in 2.5h of video per day. Moreover, in our experience, the average data usage in the field is approximately 0.5 GB a day per camera. However, motion triggered recording may not be an option for every customer. For example, some customers may want scheduled or continuous recording, whether it be for personal reasons or regulatory requirements. Naturally, continuous recording consumes more bandwidth than motion recording, but there are other factors at play. 


Adjust the bit rate

As IPVM puts it: “Bandwidth is like vehicle speed. It is a rate over time.” Therefore, bit rate impacts cloud CCTV bandwidth requirements. As mentioned previously, cloud CCTV can be optimized for real world networks. For instance, in our experience the majority of cameras in the field require a bit rate of only 400-600 kbps per camera.  


Change the resolution 

The greater the resolution, the harder it becomes to compress the video to a low bit rate, and so the greater the impact on the network. Therefore, if you’re looking to reduce the bandwidth requirements for cloud CCTV, you can lower the resolution. Videoloft can also take a very high res still image for each motion event at the maximum resolution of the camera. For some sites, this’ll be preferable to sending high resolution video to the cloud, as the low resolution video shows you what happened, while the high resolution still provides fantastic detail.

Test your upload speed

Another perk of the Videoloft app is that you can use it to test the upload speed at customers’ site. In other words, whether the bandwidth can cope with the number of cameras you’re planning to install. To check the network upload speed, from the app’s main menu tap on ‘Tools’, then ‘Speed test’. This will automatically start the upload speed test and takes less than a minute. Once the test is complete, the app will advise you on the optimal as well as a maximum number of cameras.

Case study: Remote mine protected using Videoloft cloud

Low bandwidth isn’t a barrier for cloud based CCTV, and a good example of this is a story of one of Videoloft’s many customers. With expensive machinery and a remote location, security at a mining company’s site in South Africa was a top priority. Needing CCTV and intrusion detection at their perimeter they contacted one of Videoloft’s installers. As the internet connection was provided using 3G, bandwidth usage had to be kept to a minimum. 

Using Videoloft’s SD video and high resolution stills recording mode allowed for reduced bandwidth usage, but also maintained the integrity of the security solution. This reduced the bandwidth used to send the recordings to the cloud, but provided the client with high quality 5MP images for each motion event. In addition to this low bandwidth mode, the Videoloft software running on the cameras constantly monitored the network connection. It dynamically adjusted the video bitrate if the network struggled to ensure that video can always be sent to the cloud. Both the security professional and the client were satisfied with the solution, and quality of the site’s security wasn’t compromised.


Bandwidth concerns shouldn’t stop you from adopting cloud CCTV

To sum up, regardless of the type of internet you’re using, bandwidth requirements for cloud based CCTV aren’t insurmountable. Depending on your customers’ requirements, you can adjust some (or all) of the above discussed elements to lower the impact on bandwidth. Despite various benefits of cloud CCTV, its flexibility and scalability alone are sufficient for you to consider moving to cloud.
