Our take
SmileCAM-USB SU-320 is a documented low-resolution camera whose distinctive feature is powered pan and tilt. Sintec lists motion tracking and VGA/CIF modes, while the guide shows an older USB and RS-232 setup. The historical Amazon ASIN is not verified.
A legacy telepresence or observation setup that can support the original software and values powered movement over modern resolution..
It is not for modern HD meetings, a simple current UVC webcam installation, buyers who need confirmed present-day software, or a setup that expects the camera to work from USB alone without checking the guide.
Pros & cons
What could work for you, and what to consider before buying.
What works in its favor
- Sintec identifies the SU-320 USB model separately from the PST-320 composite-video camera and its different specifications.
- The record lists VGA/CIF modes, 300-degree pan, 60-degree tilt, movement speed, focus distance, and USB power.
- Software motion tracking and remote control are explicitly described, with current service operation left unresolved.
What to weigh up
- The highest listed image mode is VGA at 15 fps, and its alternative CIF mode is lower resolution.
- The user's guide targets old Windows versions and documents a USB plus RS-232 setup path.
- The source ASIN, cable contents, microphone, and present host/application compatibility remain unverified.
The key details
| Model covered | SU-320 |
|---|---|
| Documented video modes | VGA 640×480 at 15 fps and CIF 352×288 at 30 fps in the SU-320 record |
| Focus and framing | 60-degree stated view, 30 cm-to-infinity focus distance, and powered 300-degree pan/60-degree tilt |
| Light and lens privacy | No integrated light or physical lens cover is documented |
| Integrated audio | Microphone presence and pickup performance are unknown |
| Connection and mounting | USB 1.1; the legacy guide describes USB plus RS-232 and Windows 98/Me/2000-era software |
| Identity and setup limits | USB SmileCAM SU-320 is distinct from the PST-320 composite-video camera; ASIN B001MV1MNK is not mapped |

What the features mean for you
The USB SU-320 and its sibling boundary
Sintec's product record names SmileCAM-USB as SU-320 and describes a webcam that connects through USB. A separate block on the same page describes the PST-320, a CCD camera with composite video and RS-232/RS-485 control. Those are different products, so none of the PST-320 sensor or connector details belong to this review. The historical candidate uses SU-320 and ASIN B001MV1MNK; the source page and user guide identify the model, but neither establishes that Amazon code. Search by SU-320 and check the exact unit and control accessories.
A clear but limited video-mode ladder
For the USB SU-320, Sintec lists a 1/3-inch CMOS sensor and VGA 640×480 at 15 frames per second, plus CIF 352×288 at 30 fps. That makes the tradeoff explicit: the faster listed mode is also the smaller image. A 320K sensor reference and the mode table do not support an HD claim. The product page gives no 1080p60 or 60 fps path. Application and driver negotiation may affect what a legacy computer exposes, so these documented modes should not be read as a guarantee for a modern video-call app.
Powered movement and the stated viewing angle
The manufacturer lists 300 degrees of pan, 60 degrees of tilt, and motion up to 90 degrees per second. That is a meaningful distinction from a static clip camera and is paired with automatic tracking and remote-control software in the product description. It is still an old software-controlled device, so present operation of the tracking service is not established. Sintec gives a 60-degree field of view but does not state whether that figure is diagonal, horizontal, or vertical; the category's diagonal-angle filter therefore remains unknown. The source gives a 30-centimeter-to-infinity focus distance, not an autofocus guarantee.
Legacy wiring and setup
The user guide describes driver installation for Windows 98, 98 SE, Me, and 2000, bundled ezNetmeeting and ezWebCam21 software, and a setup route that connects USB and an RS-232 serial cable. The manufacturer record says the camera is powered from USB at 5 volts and lists a 3.1-meter cable. The available sources do not confirm which cables ship with this historical listing or whether current USB hosts expose the camera as a standard UVC device. A buyer should confirm the exact package and software path before designing an installation around it.
Who should consider SU-320
This model may suit a restoration, telepresence, or observation project that has compatible legacy hardware and needs a camera head that can move under software control. It is not a reasonable default for an ordinary modern desk call: VGA/CIF capture, USB 1.1, driver installation, and unclear current application support all create setup risk. Microphone presence and audio performance are not established, so plan an independent audio path. This is an assessment of the product documents, not a hands-on test of tracking, movement noise, picture quality, current service, seller condition, or availability.
What else to compare
For automatic movement with a current-documented model, the released OBSBOT Tiny 4K is a stronger modern option; its tracking and privacy behavior differ from the SU-320.
Before you buy
Does the SU-320 record 640×480 at 30 fps?
No. Sintec lists VGA 640×480 at 15 fps and CIF 352×288 at 30 fps for the USB model.
Does the product page's PST-320 block describe this camera?
No. PST-320 is a separate composite-video model; this listing is the USB SmileCAM SU-320.
Is ASIN B001MV1MNK confirmed for the SU-320?
No. The product record verifies the model, but the historical Amazon ASIN and offer contents remain unresolved.

The decision
Choose SU-320 for a compatible legacy installation that needs powered pan/tilt. Confirm the software and included control cable because the historical offer is not mapped.
