Anabon field guides · Surveillance Knowledge
Form factors, lenses, night imaging, deterrence, panoramic and thermal technology explained in the installer's terms — what to spec for which job.
An IR camera lights the scene with invisible light; a thermal camera reads the heat the scene emits. What that changes for detection range, temperature measurement and fire detection, and where thermal is not a fire alarm.
A stitched 180° camera gives the NVR one wide image; a non-stitched dual-lens unit gives it two channels. What that changes for channels, bandwidth and mounting, and when one panoramic camera beats two.
A recording-only camera documents the incident; an active deterrence camera tries to interrupt it. How EW and AEW work, where they pay, and how to set expectations with the customer.
A fixed 2.8 mm lens is right where the camera is close to the subject; a varifocal lens pays off where distance or scene width is uncertain. The arithmetic, the labor side and the CASE varifocal SKUs as printed.
IR, white light, PhotonX and NightBright produce very different night footage. Here is how each works, what the printed lux and WDR figures do and do not promise, and which CASE camera fits which night scene.
Turret, dome or bullet is a mounting-position decision, not a style decision. One comparison table, five CASE examples with printed specs, and quick picks by site type for installers.
