The premium QT504is ideal for home or business use with a 4-channel multiplex DVR including industry-standard H.264 video compression, which compacts video file size, preserves quality, and maximizes recording time. Record with broadcast-quality full D1 on each channel, and get smooth continuous video motion in return. The DVR's multiplex feature allows you to simultaneously record, view live or recorded footage, play back footage, back-up files and remotely monitor and manage your DVR on your computer network or the Internet, without any recording loss. 

Don't wonder what's happening while you're away - see for yourself on your compatible smartphone, PC, or Mac computer.  Q-See offers a mobile surveillance feature that lets you easily view your cameras' live feeds via the internet or 3G/4G smartphone. Record using motion detection mode (includes email alerts), schedule or manual mode, and stay connected by backing up or transferring your video footage to a PC, USB flash drive or hard drive. Universal Plug and Play (UPnP) is a new network protocol that is designed to allow easier connections of networked devices such as computers, mobile devices and network-capable security DVRs. Q-See has incorporated UPnP technology into this DVR to allow them to automatically - and seamlessly interact with other devices on the network - without the need for special software or time-consuming configuration routines. If your router is UPnP-capable, Q-See's DVRs are ready to go to work!  

QT series DVRs are equipped with Central Management Software (CMS).  This advantageous feature allows you to access multiple same-series DVRs within your network or through the Internet.  If you have two or more same-series DVRs  in various locations (home office/business site, multiple retail sites, regional locations, etc.) you can conveniently view up to 64 cameras on one single screen.  Additionally, up to 10 users can remotely log into the DVR at the same time and dual-stream technology allows for easier internet access with lower bandwidths. 

All Q-See DVRs support worldwide remote monitoring and perform well with home or business computer networks and a variety of security cameras.   Rely on Q-See to save you money, and with competitive prices, strong warranties, easy installation, and lifetime technical support.  Peace of Mind, Anywhere, Anytime.
