THE BUYING GUIDE

Plan what happens after an event.

Active deterrence combines selected detection functions with a supported response such as light or audio on particular products. Choose the target event and decide where an alert is appropriate, then check the exact camera functions, schedules and recorder integration. These features should support a considered site response rather than replace it.

Plan the scene first.

List the target areas, approximate viewing distances, daytime and night lighting, cable routes and retention needs. This makes it easier to compare cameras on useful evidence rather than headline megapixels.

BEFORE YOU ORDER

A few useful answers.

Planning your installation?
Talk through your requirements with us ↗

Does more resolution always give a better result?

Not by itself. Lens, target distance, lighting, exposure and compression affect useful detail. Compare sample requirements for the actual scene.

Will any IP camera work with any NVR?

Check the recorder compatibility information, supported protocols and firmware. Recording, audio and analytics can have different requirements.

Do all models include a memory card?

No inclusion should be assumed. Check the exact listing for card support, capacity and supplied accessories.

How do I choose between a fixed and adjustable lens?

Choose from the required view and installation flexibility. Confirm the lens range and field-of-view specifications for the exact model.
