Bandwidth-Optimised VMS vs Standard-Bitrate VMS
At scale, the codec and compression strategy of a video management system drives more cost than any other single factor. Here is how a bandwidth-optimised VMS changes the storage, network, and total-cost equation versus a standard-bitrate platform.
Bandwidth-Optimised VMS
Smart-codec / low-bitrate architectureA video management system engineered to minimise the bitrate each camera transmits and stores without sacrificing usable image quality, using H.265 / smart H.264, dynamic frame rate and GOP, region-of-interest encoding, motion-based recording, and proprietary compression. The result is dramatically lower network and storage cost across the retention window, and the ability to run cameras over constrained links such as 4G/5G.
Best For:
City-wide and multi-site deployments with thousands of cameras
Remote or mobile cameras on 4G/5G/cellular backhaul
Long retention windows where storage cost dominates TCO
Election, transport, and smart-city programmes
Standard-Bitrate VMS
Default constant-bitrate recordingA video management system that records cameras at default or constant bitrate with limited codec optimisation. It is simple to configure and adequate for small estates, but bandwidth and storage scale linearly with camera count, resolution, and retention, making it costly and sometimes infeasible for large or distributed deployments.
Best For:
Small single-site estates with abundant bandwidth
Short retention windows
Deployments where storage cost is not a constraint
Proof-of-concept or pilot installs

Frequently Asked Questions
How much can bandwidth optimisation actually save?
VMukti developed proprietary video-compression technology that reduces bandwidth usage by up to 96% versus naive encoding, on top of standard H.265 savings. Because bandwidth and storage are recurring per-camera costs paid every day across the full retention window, even a 50-70% reduction reshapes the total cost of ownership of a large deployment, and the headline savings are what make cellular-backhauled and city-wide camera fleets financially viable.
Does aggressive compression hurt evidential image quality?
Not at tuned settings. Smart codecs and region-of-interest encoding preserve detail where it matters (faces, plates, motion) and economise on static background, while dynamic GOP and motion-based recording avoid spending bitrate on empty scenes. VMukti tunes compression so that ANPR reads plates at speeds up to 200 km/h and AI models keep their accuracy, while bandwidth and storage drop sharply.
Why does bitrate strategy matter more at scale?
Because the cost is multiplicative: bitrate per camera, multiplied by camera count, multiplied by retention days, multiplied by every site. A small estate barely notices the difference; a city-wide programme with thousands of cameras and long retention sees storage and network become the dominant line item. That is why a bandwidth-optimised VMS is effectively a prerequisite for large public-safety and smart-city deployments.
Can a bandwidth-optimised VMS run cameras over 4G/5G?
Yes. Low-bitrate encoding is what makes cellular backhaul practical. VMukti has deployed 4G-SIM-based cameras at scale, including more than 12,000 cameras for a single state election and 4G-SIM intelligent monitoring across 23,000+ locations in a state assembly election, which would be unworkable on a standard-bitrate platform.
