Bosch 4K Tested

(Member Only)

4K promises more pixels but does it undermine WDR and low light performance? We tested the Axis 4K camera and there were certainly issues. Now, we tested the Bosch 4K camera, the Dinion IP Ultra 8000 against the 4K Axis P1428-E and Arecont 10MP ...

Testing Day vs Night With IR

A Major Flaw in Long Lenses and PTZs Found

(Member Only)

Theoretically, long lenses should let you capture faces and license plates very far away. For example, over 900 feet away from a 1080p camera one should get over 40ppf from a 100mm lens. But how well does this work in practice? In this test, we...
