Have the fisheye camera installed

A fisheye camera combines a wide area into a single strongly distorted image. Software can create clear partial images of it; this is called dewarping. The installation is only usable when both the chosen viewpoint and the viewing and searching capabilities of your recorder and viewing software match.

Have the fisheye camera installed

Place based on the actual space

A central ceiling position can provide a panoramic view, but cabinets, beams, and hanging objects can block parts of the scene. Indicate on a floor plan which passages should remain visible. Check those points in a test image. A wide lens does not look through an obstacle and does not automatically provide sufficiently recognizable details at every location.

Evaluate the edges separately

Do not merely focus on the appealing overall picture. Allow someone to walk along the important edges of the area and examine the relevant sub-image. The available pixels are distributed across a large area. If a small detail at one entrance is crucial, it should be evaluated to determine whether a supplementary focused camera is more suitable for that task.

Choose where the image correction takes place

Depending on the combination, the camera, recorder, or viewing software can convert the round image. Check which views are supported and how they are offered to a user. A correct partial view in the manufacturer app does not prove that the same function is available through another recorder. Let the intended chain be confirmed before purchase.

Make looking back part of the trial

Record a recognizable playback route and view it using the normal playback function. Check whether other parts of the recorded image can be selected later, or whether only the configured display is preserved. Export a short fragment and see what a receiver sees from it. This prevents expectations that the chosen storage method does not meet.

Document viewing stands and operation

Note which position is intended for overview and which for detailed inspection. Explain to the user when looking around digitally, so that it is not confused with physically rotating the camera. Keep the mounting orientation and settings with the system. A later changed ceiling or wall mode can noticeably change the presentation.

Frequently asked questions

Is digital looking around the room the same as turning a PTZ camera?

No. With a fisheye, you choose a portion of the available image; the camera does not need to physically move for this to happen.

Can every NVR correct a fisheye image?

No. Check the supported combination and also test included images.
