Video Compression Comparison

Choosing the right camera to match your broadband plan is vital for optimum performance and ensuring good camera function.

Refer to our System requirements page for basic data relating to hardware and software requirements.

On this page we want to detail the importance of matching your broadband plan with the camera you want to purchase.
Many ISP (Internet service provider) customers are on an ADSL 128k upload, unlimited download plan unless you have paid for higher monthly data upload capacity.

Below is a diagram giving a visual representation of the 3 different video compression options available at present. Video compression translates the images the camera sees into a JPEG, MPEG-4 or H264 format to transfer the images across the Internet. If the video compression of the camera isn't suited to your broadband plan, the camera function will operate so slowly that it isn't worth having, and it will deplete your monthly data upload allocation very quickly.

H264 Video compression comparison

As you can see in the diagram, a JPEG camera uses 5 times the amount of data transfer bandwidth as an H264 camera to achieve the same picture quality or speed. If an H264 camera needs 128k bps for a particular operation, a JPEG camera will need 640k bps. If you are on a 128k bps upload plan, a JPEG format camera will display video images as a series of jerky images. An MPEG-4 format camera is an improvement over the JPEG camera, but it will use twice the broadband capacity of the H264 format camera.

And now in 2015 H265 is beginning to appear in some products, mainly IP cameras. The requirement for H265 to be accepted was it had to be twice as efficient at video compression as H264. By the looks of it they have succeeded. The bandwidth and storage requirements are about half H264.
