Short answer: To choose an inspection camera, define one real job and measure it before comparing screens or resolution. Record the smallest opening, distance to the target, bends, lighting, environment and whether live viewing is enough. The Hayve listing provides a useful worked example: a 7.9 mm lens, 5-metre semi-rigid cable, eight adjustable LEDs and a 4.3-inch built-in screen. It also states up to four hours from a USB charge. None of those figures makes the camera universal, so every unlisted requirement should remain unresolved until the manufacturer or seller documents it.
Define the inspection before comparing products
A useful brief names the target, access point and decision the image must support. Looking behind a trim panel, inside a dry void and around a stationary machine are different jobs even when they use similar camera shapes.
Separate essential requirements from preferences. Lens diameter, route and safe operating conditions are essential; a larger screen may be a preference unless the operator must identify very small details.
- Name the target and the question the live view must answer.
- Measure the narrowest opening and total route to the target.
- Count significant bends and identify surfaces that may snag the cable.
- Describe lighting, temperature, moisture and contamination conditions.
- Decide whether live viewing alone meets the workflow.

Compare physical fit before image specifications
A lens that cannot enter the route makes every other feature irrelevant. Compare the full route with the camera diameter, then consider whether the cable is long enough and controllable enough to reach the target.
The Hayve example lists a 7.9 mm lens and a 5-metre semi-rigid cable. It does not provide a bend-radius figure, so a sharply curved route remains an unanswered fit question.
| Priority | Question | Hayve example |
|---|---|---|
| 1 | Will the camera pass the narrowest point? | 7.9 mm lens |
| 2 | Can the cable reach and follow the route? | 5 metres, semi-rigid |
| 3 | Can the target be lit without excessive glare? | Eight adjustable LEDs |
| 4 | Is the viewing setup suitable? | 4.3-inch built-in IPS screen |
| 5 | Are all operating limits documented? | Several limits remain unspecified |
Choose the viewing and power arrangement
A built-in screen keeps the viewing device with the camera. The Hayve listing says its model works without Wi-Fi, an app or a smartphone, which may suit a shared bench or a buyer who does not want phone pairing in the workflow.
The listing states up to four hours of use from a USB charge. Treat that as the published maximum wording, not a guaranteed duration for every session, and confirm charging arrangements before a time-sensitive job.
Limits that should stop a purchase
The current listing does not state focus range, operating temperature, chemical resistance, a liquid-use procedure, minimum bend radius, image saving, export, replaceable parts or compatibility with named equipment.
If the job depends on any missing detail, do not substitute a general marketing phrase for evidence. Choose a product with explicit documentation for that requirement.
