The spec sheets sit side by side and invite a comparison on resolution, field of view, and night vision range. Those numbers rarely decide anything, because both products clear the bar for their price. What actually differs is who ends up owning the device after you have installed it.
Two different ideas about what you bought
A camera built on an open platform is a device that speaks standard protocols and joins an ecosystem your other devices can also join. It is designed to be one component among many, possibly from different makers, controlled by whatever you already use.
A camera from a closed ecosystem is a device designed to be part of that maker's system. It works very well inside it. The recorder, the app, the storage, and the other cameras are all from the same place, and the integration is the product.
Neither is wrong. They are answers to different questions. The mistake is buying the second while expecting the first.
What you gain from the closed system
Integration is the real advantage. Multiple cameras, a recorder, and the app are designed together, so features that span devices work without configuration. Playback is consistent, firmware updates are coordinated, and there is one place to look when something misbehaves.
Recording is usually better thought through. A dedicated recorder with its own storage is a more robust answer than a card in each camera, and it does not depend on any single camera staying powered.
Support has one throat to choke. When something breaks, there is a vendor responsible for the whole chain rather than a camera maker and a platform operator pointing at each other.
What you give up
You give up mixing. Adding a camera from another brand later usually means running a second app, and the two systems do not share automations without an integration somebody has to maintain.
You give up some local control options, depending on the maker. Some closed systems expose a standard stream you can pull into third party software. Some do not, and what you can do with your own footage is defined by what the vendor chooses to allow.
You give up the option of moving piecemeal. If you later decide the ecosystem is wrong for you, the exit is replacing the system rather than replacing one device.
What you gain from the open platform
Choice and price. Many makers build on the same platform, so there are more form factors at more price points, and you are not locked to one vendor's release schedule for a feature you want.
Interoperability with what you already own. If your other devices are on that platform, the camera joins them, and automations that span a sensor and a camera are straightforward rather than a project.
A path that does not require replacing everything. If one camera disappoints, you replace one camera.
What you give up on the open platform
Consistency between makers. Two cameras from different factories on the same platform can behave differently in the details that matter, because the platform defines the interface, not the implementation. Event detection, night switching behaviour, and stream stability are all areas where implementations diverge.
You also inherit a dependency on the platform operator. If the cloud account is unavailable, features that route through it fail, even though local recording continues. This is true of most platforms and is worth knowing rather than fearing.
The questions that actually sort it
Do you already have a system? If you have cameras and a recorder from one maker, adding to it is almost always right, whatever the numbers say. The value of one app and one timeline is larger than a marginal resolution advantage.
Do you need to record continuously or by event? Continuous multi camera recording is where a dedicated recorder earns its cost. Event based recording with local storage works well on either approach.
Will you want to pull the stream into something else? If the answer is yes, check whether the specific model exposes a standard stream before buying, and check it per model rather than per brand, because it varies inside product lines.
How many cameras will you have in two years? Below four or so, the integration advantage is modest. Above that, the value of one system grows quickly, and the cost of mixing grows with it.
Are you adding to an existing smart home? If your switches, sensors, and plugs are on a platform, a camera on the same platform gives you automations that a closed camera cannot. That is often the deciding factor and it is not on any spec sheet.
The Tuya camera comparison walks through these questions with the actual differences in stream access, storage, and ecosystem behaviour. The security camera range covers both platform based and standalone models side by side.
For the manufacturing side, including which models expose local streams and what the firmware support commitment is, see XingLiao Tech, and the camera specific notes at the CCTV camera manufacturer page.
The short version
Both products take adequate video. Decide on the system you are joining, how many cameras you will have, and whether you need to get your own footage out. Those three answers pick the product, and the resolution line does not.
