12 Channel Hybrid DVR for HD-TVI / HDCVI / AHD / CVBS / IP with Alarm / Sensor

Analog HD Support
Year Warranty

Designed for universal compatibility, our 12 channel hybrid DVR supports up to 12 x security cameras with support for HD-TVI, HDCVI, AHD, CVBS, and IP cameras. Built-in HDMI and VGA outputs allow you to use various monitors for display with USB 3.0 / 2.0 ports used for mouse control and external hard drive backup. 8 channel audio inputs allow microphones to be connected and a 1 channel audio output allows output onto an external speaker if necessary. RS485 terminal connections are provided for PTZ control. Alarm / sensor terminals are provided to hook up external sensors and alarms for triggering DVR action. Local and remote viewing is supported either through the browser, software, or iOS and Android app.

High Definition

Ultra HD support allows the DVR to support analog cameras up to 5MP (2560x1960) and IP cameras up to 4MP (2592x1520). This provides clearer and more detailed images for a better recording experience.

HD-TVI, HDCVI, AHD, CVBS, IP Camera Support

The DVR has broad support for a wide range of camera formats. Mix high definition analog cameras with their IP counterparts for seamless integration. Note that when using IP cameras, they will need to be plugged into a router / switch since the DVR itself does not have dedicated RJ45 ports for IP cameras.

* When using H.265 IP cameras, please make sure to set the compression on the IP camera to H.264 in order to work on this DVR
** The DVR can support up to 16 analog channels and 8 IP channels

Cloud Support

Skip port forwarding by enabling cloud support on the DVR. With cloud support enabled, access to the DVR is as easy as installing the DVR application or iOS / Android app and then scanning the QR code for access.

* To use the iOS / Android app, download RXCamView from either the Apple App Store or Google Play Store

Audio In / Out

Install microphones to your setup to capture sound with your recordings. Audio output allows a speaker to be connected.

Alarm / Sensor Terminals

Alarm and sensor terminals allow you to hook up external sensors (PIR sensor, magnetic contacts, sirens, and more) so that the DVR will trigger an action when the alarm / sensor is activated.
