Reading the situation
The choice starts with the task: overview of a complete space, recognition at a door or both. For brands such as Dahua and Hikvision, mounting, image correction, and available displays vary per model and recorder.
advice
Choose and install a fisheye camera
A fisheye camera gives a wide overview from one position. That is useful in a hallway, shopping floor or central space, but a large image is not automatically a usable detail image.
First evaluate
Check ceiling height, obstacles, light and the places where a person is small in the frame. Also check whether the recorder or viewing software supports the desired dewarping display before comparing a camera on brand alone.
The correct next step
Choose the mounting position on the relevant overview and, if necessary, combine a fisheye with a focused camera at an entrance. Capture the model, recorder, channel settings and the chosen views for the transfer.
Check after the change
Test live view and look back at the device that is used daily. Walk through the relevant zones, compare the overview with the detail needs, and check whether nightlight and recording provide the same usable situation.
Frequently asked questions
Does a fisheye always replace multiple regular cameras?
No. A fisheye provides a wide overview, but at a greater distance a focused camera can be more suitable for recognition.
Does every fisheye work the same on an NVR?
No. Check the exact camera, recorder, and software combination, especially for image correction and additional displays.
