COSEC DOOR PVR is a highly secure and contactless biometric device that reads the internal vascular pattern of the palm. These patterns are unique to each individual and exist underneath the skin layer, which cannot be forged thereby making it most secure compared to other biometric technology. To give accurate result, COSEC DOOR PVR uses fujitsu biometric palm vein scanner to provide utmost security and hygiene. This makes COSEC DOOR PVR more secure in comparison to other biometric devices. Being contactless and technologically advanced, it is appropriate for places like hospitals, chemical industries, nuclear stations, factories, corporate houses, R&D centres, financial institutes and many others where security and hygiene are of utmost importance. Hence, with this unique palm vein recognition system, COSEC DOOR PVR is capable of storing up to 20,000 user templates and has up to 1,00,000 events storage capacity. It proves to be extremely secured for Time-Attendance and Access Control applications with false acceptance ratio less than 0.00008%.
CCTV (closed-circuit television) is a TV system in which signals are not publicly distributed but are monitored, primarily for surveillance and security purposes. CCTV relies on strategic placement of cameras, and observation of the camera's input on monitors somewhere.
