Is a security camera patented?

Short answer: specific designs of a security camera have been patented many times, but "a security camera" as a general idea is not what is protected. What matters is the exact combination of features in your version.

What our index shows
  • 798 US and WO patent publications since 2000 have a title matching “securitysurveillance camera” or a close variant (our index of 9.7 million patent families; one publication per family).
  • Among the 403 best keyword matches we examined, 158 were published in 2020 or later, and the earliest was published in 2000.
  • Most frequent assignees in those matches: HANWHA TECHWIN CO LTD (15), JAPAN ELEVATOR SERVICE HOLDINGS CO LTD (12), HONEYWELL INT INC (11), KUNA SYSTEMS CORP (9).
  • Most common patent classes (CPC subclasses): H04N (303), G08B (193), G06V (71), G03B (52).

Counts come from keyword matching on titles and abstracts, so they are indicative, not a legal count. Some matches are different products that share a word.

What this means for your idea

Because patents cover specific combinations of features, the useful question is not “has a security camera been patented?” but “has my combination of features been described before?” Consumer electronics are among the most heavily patented areas; the specific circuit, mounting, or interaction is what distinguishes a design.
