Here is why this specific search string tells a story about the industry:
Essential for cameras placed near glass entries or areas with harsh shadows, WDR balances light and dark areas to ensure the image remains clear.
A fixed camera draws less power than a PTZ (typically 5W to 8W vs 25W).
Before you finalize your purchase based on the research, print this checklist.
If using a fixed box camera (not a bullet/bullet), you must physically adjust the back focus. Point the camera at an object 15 meters away. Loosen the set screw, rotate the lens until sharp, lock it. If you skip this, your network camera will output soft video forever.
A fixed network camera forces discipline. You cannot frame the shot lazily from your desk chair. You cannot rely on digital zoom (which is just cropping). You must engineer the scene.
A 6mm fixed network camera aimed at a gate provides license plate capture (LPC). Because the lens is fixed, the pixel density at the gate is mathematically constant. This allows for reliable ANPR (Automatic Number Plate Recognition) without the autofocus hunting that varifocal lenses suffer from in rain or snow.
