The digital peephole viewer device of the present invention comprises a housing, an image capture unit, a signal processing unit, a display unit and a connection means. The image capture unit has a first lens to receive the optical images captured by the door lens assembly. The signal processing unit converts the optical images into continuous dynamic digital images. The display unit presents the continuous dynamic digital images. The connection means integrates the housing with the door lens assembly."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Digital peephole viewer device","description":"The present invention discloses a digital peephole viewer device, which integrates with a door lens assembly on a door board to acquire optical images captured by the door lens assembly, converts the ","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8487998","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
