What Load Really Depends On (Spoiler: Not Megapixels)Ask anyone in the industry what load depends on and you get the classic answer: number of cameras, resolution, frames per second. Which is about as useful as saying that your health depends on food and sleep. Technically true. Practically useless.
In the real world, system load is almost entirely driven by functionality. Not by the logo. Not by the sticker on the box. Not by how loudly it says Smart. It depends on what the system actually does with the video stream.
Historically it was all very simple and oddly honest.
Camera looks. Disk writes. Archive grows. Once in a while someone remembers that they need to review something and digs into this digital attic. The camera understands nothing. It just sprays the stream at the recorder. Like a night guard who sees everything and comprehends nothing. Then cities grew. Warehouses, parking lots, malls and use cases multiplied. Archives inflated to terabytes. False alarms became a lifestyle. The operator turned into a human time machine, rewinding yesterday for a living.
At some point it became obvious: "record everything forever" is not reliability. It is architectural laziness. You need motion detection, analytics, noise filtering. Not for the buzzwords, but for survival. Less archive, fewer useless alerts, less pointless human work.
Ten Years Of "Smart" On The Box, One Answer In SupportEnter marketing. Boxes got new titles: Smart DVR, AI Camera, Intelligent VMS. Any device without "Smart" in the name felt obsolete before it left the warehouse.
If you believed the brochures, ten years ago video surveillance should already have been able to:
- understand who is in front of the camera
- tell a cat from an intruder
- ignore snow, rain and shadows
- and ideally predict what you are trying to see
Now open user forums or Reddit threads and you land in a parallel universe.
The daily tech support dialogue is almost always the same:
- "It is not detecting anything."
- "Did you update the firmware?"
Detects the curtain moving: update the firmware.Fails to detect a human: update the firmware.Camera does not connect: update the firmware.Connects, but only on Tuesdays: update the firmware.Users have been updating recorders, cameras and their own hope for years. The miracle stubbornly refuses to appear.
On top of that you get some industry "traditions":- the pretty boxed camera refuses to connect until you install the latest update
- the connection workflow is so weird it feels easier to align a satellite
- configuration still requires Internet Explorer that your modern machine simply refuses to install
- the UI looks like it was designed for an 800×600 CRT and a ball mouse
- "security" is solved with a password the size of a Victorian novel
And no, it is not because users are stupid. The problem is in the architecture. In software that was originally built for a different era and very different tasks. Rewriting everything from scratch is painful and expensive for the manufacturer, and terrifying for integrators and customers who know exactly what "major update" means: risk, stress and night shifts. So the industry lives in a permanent mode called "one more firmware".
Why A Box Does Not Become Smart After A New FirmwareMost DVRs and "smart" cameras are powered by a compromise System on Chip that was perfectly fine in the era of "write stream to disk". The world has moved on a bit since then.
Modern analytics needs to:
- decode each frame
- run it through several layers of detectors
- decide what to do next
In other words, software that was built for "continuous recording" is being stretched into "AI platform". That is how you end up in the firmware Groundhog Day. The hardware is already at its limit, the architecture was never designed for this, but marketing really wants one more checkbox in the spec sheet. You cannot turn a cheap old NVR into a serious AI system by flashing it often enough. This is not about "optimizing the code". This is physics. If the box has a modest SoC that already struggles with H.265, it will not suddenly start calmly running face detection, OCR, smoke detection and speech to text on top. The laws of thermodynamics are not impressed by your roadmap.
"Just Record Video" Is Cheap, "Understand Video" Is NotPlain continuous recording is easy mode. The camera sends a stream, the system writes it to disk. H.264 in, H.264 to storage. H.265 in, H.265 to storage. No analysis, no transcoding. Load is minimal. Everyone is happy, at least until someone asks "what exactly happened yesterday at 3:24 AM".
H.265 saves disk space, but with a catch. You cannot just play that stream in a browser. For the web you usually have to transcode it to H.264. So you save money on storage and spend it on CPU or GPU. One way or another, you pay.
SmartVision lets you make an explicit choice. Record the stream "as is" over ONVIF or transcode it for maximum compatibility. But the second you want to understand what is going on in the scene, the rules change. Analytics starts with frame level access. Every frame must be decoded, passed through a light detector to check that the image is not frozen and that there is real motion, then forwarded to heavier modules: object detection, face recognition, license plates, smoke, fire, sound, you name it. To keep the system alive you can downsample in time. You do not have to analyze all 25 or 30 fps. Sometimes 10 fps is enough. It is still a heavy workload. GPUs love this type of task. But with a sane architecture and modern software you can build a very capable intelligent system on regular CPUs too. The key point is this: software decides how to distribute the load. A closed black box does not give you that kind of control by design.
Software vs Appliance: Who Owns The BrainThe main difference between software based video surveillance and the classic recorder is simple. Freedom and scalability.
What software gives you:
- you are not locked to a single camera vendor
- you do not have to replace hardware to get new features
- even a budget camera can become part of an intelligent system because the brains live in the software stack, not inside a sealed plastic box
- you scale compute by upgrading a standard PC or server, not by throwing away a "next generation" NVR every few years
How the appliance world usually works:
- vendor X expects you to use cameras X
- want parking analytics? welcome to product line Y with its own logic, limitations and sometimes unique protocol flavor
- want to monitor a nanny by sound, detect crying, shouting and adult presence? here comes another specialized box
- need license plates, faces, age and gender, people counting and smoke detection near the warehouse? that will be yet another "series"
The end result is predictable. A zoo of devices, protocols and user interfaces. Every new requirement drags in a new appliance, a new firmware, a new integration headache. In the software world, the script is different. You build architecture once, then add modules. Need a smoke detector? you connect it. Need speech transcription? you enable it. A new model for behavior analytics arrives? you update the software, not the camera fleet.
When A Small Software Team Beats A Giant Hardware BrandLarge corporations are defined by their legacy. Thousands of developers, committees, release trains and a lot of sacred code that no one wants to touch. As long as the old web interface still technically opens, it is very hard to justify rewriting it, even if customers run it inside a Windows XP VM just to configure cameras. Smaller teams live in a different reality. "It does not work at a customer site" is not a ticket for some quarterly review. It is a fire that needs putting out today. There are no holy relics like "that ancient CGI page from 2011 that integrators are used to, so do not touch it".
SmartVision was built as software without that baggage. Not "let us hack one more checkbox into the NVR menu", but "let us design the system around a modern service architecture and use AI where it actually helps". Services get split by responsibility. Analytics, storage, UI, cloud access each have their own role. You can improve, replace or scale parts without risking the entire stack. That is the sort of evolution that is practically impossible inside a locked appliance.
What Software Already Delivers That A Box Cannot FakeBy the end of 2025 SmartVision could already:
- recognize license plates from different countries
- run OCR and read QR codes
- transcribe speech
- detect objects in the scene
- recognize faces and search for similar ones
- detect smoke and fire
- maintain archive, events and timelapse
- provide cloud access on top
All of that on regular computers. No requirement to buy "flagship AI cameras" priced like a used car. In 2026 more detectors and scenarios are being layered on top. Better audio analytics here, behavioral patterns there, more context from text inside the frame. The important part stays the same. The intelligence lives in software. A boxed NVR in a similar situation tends to offer firmware version 5.4.7 with a note that "experimental feature X has been added". Then 5.4.8. Then 5.5.0. Somewhere at the bottom in small print it quietly warns that if you enable that feature, channel capacity is halved and the list of compatible cameras shrinks to a handful of models.
Why The Future Belongs To Software, Not The Next "Smart" BoxRecorders are not going away. They still have a perfectly valid niche:
- continuous recording
- simple scenarios
- minimal logic
But the moment the task moves beyond "please store this video", the balance of power flips.
Software turns:
- video and audio into data
- data into events
- events into actions
And it does this on infrastructure that you control. Need more analytics? you add a GPU or a stronger CPU. Need redundancy? you add another server. With a closed appliance the usual answer is simpler: "not enough performance? buy our new recorder".
The video surveillance industry is growing up slowly and a bit awkwardly. Lots of band aids on top of band aids. A cult of firmware releases instead of real progress. The real shift from "the box records" to "the system understands" is not about new plastic. It is about normal software and sane architecture.
You can buy a basic camera, install
SmartVision on a regular PC and get a system that, a few years ago, looked like a trade show demo. No tax for the "ultra smart AI" label on the box. No firmware marathons. No feeling that the future has been postponed until the next update cycle.
The future of video surveillance is already here. It just moved out of the black box and into software. And the best part is that what runs it now is not magic. It is engineering that finally does what the brochures have been promising for a decade.
