The D32PS 32-Channel PS Hybrid DVR with Digital Deterrent & 4TB HDD from Speco Technologies is designed to deliver hybrid IP and analog recording capabilities along with full HD display. Feature-rich performance, extensive storage, display options, and powerful search capabilities make this DVR a simple migration strategy to IP with no added licensing fee. Moreover, the ability to support megapixel IP cameras (sold separately) gives added flexibility to it. Optimized for full HD surveillance, the PS Hybrid DVR provides 2 full HD video outputs (1 HDMI, 1 VGA), which generate clear live and playback images when using HD monitors.The Digital Deterrent feature that is built into the DVR is triggered by motion detection or alarm input activation that initiates visual indications, audio warning, and advisories. The visual part of the Digital Deterrent is a strobe or light that activates when motion or an alarm input is detected. This DVR is equipped with Form C contact that activates during these events. The audio output of the DVR is a line-level output and requires an amplifier (sold separately) to amplify the signal to be heard.
