How to choose the right network camera for your project?
Quickly select the right camera model from the five dimensions of resolution, lens, night vision distance, protection level and power...
Is more megapixels always better? Choosing between 2, 4 and 8 MP
Resolution should match viewing distance, target size and storage budget. Reaching for the highest pixel count often backfires.
How do I choose between home and commercial cameras?
The two differ in stability targets, storage, power and operations. Service life and the number of users are the fastest way to decide.
Full-colour night vision or infrared night vision?
It comes down to whether colour matters at night. Full-colour models draw more power and cause more light pollution; IR is the more...
How do I choose between dome, bullet and PTZ cameras?

Cloud storage or a local NVR — where should recordings live?

How do I judge image quality from a sample unit?
Do not rely on daylight alone. Test five things on site: daytime detail, backlight, night performance, motion smear and colour reproduction.
