![]() Here are a few common things to watch out for: Be mindful of your cameras’ field of viewĮven with an LBR setting, unnecessary motion in your cameras’ field of view (FOV) can still increase your data rates and eat up storage. Again, this is using the exact same factors of 2MP resolution, high scene complexity, and recording at 15 fps.ĥ. With an LBR feature, you only need 117.2 Mb/s of bandwidth and 36.2 TB of storage – about a third of the amount required compared to a camera without the LRR mode. Now, try that scenario again with a camera that uses a LBR setting. Using a typical 2MP IP camera, capturing detailed video with high scene complexity at 15 fps, you would need a total of 360 Mb/s of bandwidth, and 111.2 TB of storage to keep your video for 90 days. You need 60 cameras to cover your entire facility naturally, you want the best image quality possible with the least amount of storage. The law in your state also requires you to use at least 720p camera resolution. ![]() Let’s say you operate a cannabis cultivation business that’s required to record video continuously for 24 hours a day, and keep that video for 90 days. Here is an example to illustrate our point: In our own tests of this feature, we’ve seen video streams that can drop below 1 Mb/s at 2MP (at 15 images or frames per second) with no noticeable degradation of video quality. Our LBR mode can reduce storage and bandwidth consumption by as much as 50% in most applications. March Networks recently optimized the H.264 compression in our ME4 Series and SE2 Series IP Cameras with a Low Bit Rate (LBR) setting that automatically manages the bit rate to give you the best video quality with the lowest bit rate, based on scene complexity. ![]() Many IP cameras have settings that can help you control the bit rate and reduce your storage. Using one of these tools, you can determine ahead of time how your camera recording will affect your storage and bandwidth, and where you might be able to make some adjustments. Many video surveillance manufacturers, including March Networks, offer these tools free of charge as a convenient way to help you plan your system. Since many factors like camera bit rate, video compression, frames per second, and scene complexity affect storage, use a CCTV or camera storage calculator to determine the exact amount of bandwidth and storage you’ll need. The majority of surveillance video is never used often, it’s only when something occurs that you’ll need to review your video and investigate. It’s one of the simplest ways to reduce your storage. If you don’t have legal requirements around 24/7 recording, configure your NVR/DVR to record on motion. For example, if loss prevention is your main goal, keep HD cameras over your high-value assets or point-of-sale terminals, but use lower resolution cameras elsewhere. ![]() That means it requires four times the bandwidth and storage capacity, so it’s important to consider exactly where you’re using HD video. The biggest factor in this discussion is IP cameras.Ī video image captured by an HD IP camera is roughly four times the size of an image captured by an analog camera. Determine where HD video is needed – and where it’s not If you’re struggling with demands for more video storage, or if you need to keep video for a specific period of time, consider the following to help extend NVR/DVR storage capacity:ġ. Many banks, K-12 schools, and emerging businesses like cannabis dispensaries are required to keep video for 30, 60 or even 90 days, depending on government requirements. ![]() This is particularly true for businesses with requirements around video archiving. Even if your recording solution is scalable, your budget probably is not, so finding ways to reduce storage without degrading video quality is becoming more of a priority. Of course, all of this storage comes at a cost. Today, purpose-built NVRs/DVRs for enterprise surveillance can accommodate over five times that amount and more when direct-attached storage (DAS) or network-attached storage (NAS) devices are added. As more businesses move from analog to high-definition (HD) IP cameras, there’s increasing demand for video recording solutions with larger storage capacities.įive years ago, commercial NVRs/DVRs with 2TB or 3TB hard drives were the norm. ![]()
