Dahua Technology N25CB5Z Overview

The Pro Series N25CB5Z 2MP Outdoor ePoE Network Bullet Camera from Dahua Technology uses a 1/2.8″ STARVIS progressive scan CMOS sensor to capture 1920 x 1080 resolution video at up to 60 fps. Four IR LEDs provide up to 164′ of night vision. The 2.7-13.5mm motorized varifocal lens delivers a 101-31° horizontal field of view and 5x optical zoom. Two-way audio communication is possible thanks to audio I/O ports. An onboard memory card slot supports microSD cards up to 128GB. microSD cards are available separately. Integrated PoE technology simplifies connectivity by enabling the transfer of power and data through a single cable. Additionally, ePoE technology offers a cost-effective solution for transmitting power and data over long distances via Ethernet or coaxial cables.

This bullet camera is housed in an IP67- and IK10-rated metal enclosure that is suitable for outdoor use in areas at risk of vandalism.Built-in IVS (Intelligent Video System) analytic algorithms monitor a scene for tripwire violations, intrusion detection, and abandoned or missing objects, as well as support for tamper & face detectionEthernet over Coaxial (EoC) technologyEnhanced Power over Ethernet (ePoE) technology enables long distance power and data transmission via Ethernet or coaxial cables up to 3281’ePoE technology converts existing coax-based analog systems into IP systems, reducing cable & peripheral device requirements, saving you time & moneyIR cut filter for day and night functionalitySmart IR and Starlight technology for low-light applicationsAuto and manual IR on/off controlSmart H.265+, H.265, Smart H.264+, and H.264 video compressionTriple streamingUnicast and multicast streaming methodsCBR and VBRMotorized DC auto iris and focus control0.98′ close focus distance5x optical and 16x digital zoomTrue wide dynamic range (120 dB), backlight compensation, and highlight compensation>50 dB S/N ratioWhite balance modes include auto, natural, street lamp, outdoor, and manualAuto and manual gain control3D-DNRMotion detection for 4 zones (rectangular)ROI (region of interest) for 4 zonesPrivacy masking for 4 zones (rectangular)Flip perspective 0, 90, 180, and 270° and mirroringONVIF compliantUp to 20 usersCompatible with Internet Explorer, Chrome, Firefox, Safari, iOS, and AndroidRecords to local PC and NAS edge storageAnalog video output for installation adjustment onlyRCA audio input and outputTwo alarm inputs and one alarm outputReset buttonIP67- and IK10-rated metal enclosure that is suitable for outdoor use in areas at risk of vandalism6kV lightning protection
