About DVRs

There are a wide variety of DVRs available and it is easy to get confused about which one will be best for your situation. The following information will help you understand the basics of Surveillance DVRs in order to help make your decision easier.

 To find the right Q-See surveillance system, first determine the number of areas that you want to observe as a Q-See DVR can monitor up to 4, 8, 16, or even 32 cameras.  The number of cameras a system can support is determined by the number of channels on a DVR; for example, an 8 channel DVR can connect up to 8 cameras. In order to allow for future expansion, it's recommended to choose a system that supports a few more cameras than what you currently need.

CIF & D1 Resolution:
 Select CIF or D1 recording DVRs depending on your preference. Choosing CIF will display a resolution of 352x240, giving a standard video image size; whereas choosing D1 will display a larger video image size for improved recognition of people and objects at a resolution of 704x480. Choosing D1 will make the video files larger and your DVR will get full faster. If the image size and detail are more important than the amount of time you can run your system before backing up the files, select D1.

Frame Rate:
In order to achieve smooth, ‘real time' video when playing back previously recorded footage, the DVR must be set to record 30 frames per second for each camera. If the DVR is set to record at a lower rate than 30 frames per second for a camera, then the video from that camera will look slightly choppy. Each camera can be set individually at different frames per second, depending on your needs for each camera. The more frames per second, the larger the file size will be for the video. 


Hard Drive: Most Q-See DVRs come with their own pre-installed hard drives. The hard drive stores video after it has been recorded, much the same way a hard drive holds a computer's data. The amount of video a DVR hard drive can hold depends entirely on the recording settings that you choose. Here are some helpful tips to maximize your hard drive storage:

·         To reduce the amount of video recorded, a DVR should be set to record video only when motion is detected. This also makes it easier to search for specific footage.

·         Additionally, a DVR can be set to record at a specified time schedule, such as during business hours, or at night.

·         Q-See DVR hard drives can be upgraded to between 2 terabytes to 8 terabytes or more, depending on the individual DVR's maximum hard drive storage support.


H.264 Compression: The best video compression is H.264, which is superior to MPEG4 and MJPEG. H.264 Compression minimizes file size in order to maximize the hard drive's recording time, as well as transfer video for viewing over the internet.

Connect LCD Monitors:
 Q-See DVRs can be viewed from a 19" or larger computer LCD or TV.  Some DVRs have an HDMI port which provides a true High-Definition viewing experience!

Operating Flexibility:
 Q-See DVRs have a user-friendly interface, for easy managing and monitoring. Simultaneously, Q-See DVRs provide significant flexibility so that their operation will fit every situation and preference.  The impressive list of operating features includes, but is not limited to:

1.  On most Q-See DVRs any of these 3 recording options (motion detection, time schedule or continuous) can be used at the same time on different cameras.

2.  Find the portion of recorded video you need with easy search options.  Search by time frame, motion occurrence, or the items that triggered an alert.

3.  With Q-See's DVR multiplex feature, you can 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. 


Remote Surveillance:  Using high-speed internet anywhere, anytime, you can remotely monitor your home, office or any property from your computer or smartphone! With select Smartphones, you can view the live feeds from one or all of your cameras, giving you an inside look into what's happening for added peace of mind. Enjoy additional peace of mind by receiving instant email alerts with snapshot images when motion is detected, when the hard drive is full, or when and if video loss has occurred. Five or more users can remotely log into the DVR at the same time and the system's dual-stream technology allows for easier internet access at lower bandwidths.

Q-See Exclusive! Multi-DVR Monitoring:
This Q-See exclusive, 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 or more 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.

·         Connect up to 100 DVRs, or up to 2000 cameras.

·         To identify if you have "Same-series" DVRs, please order within the same family, ie:

-       QT-Series DVRs include QT454, QT428, QT528, QT536, QT4532, etc....
-       QC-Series DVRs include QC444, QC40108, QC40196, etc....
-       QS-Series DVRs include QS464, QS408, QS206,etc....

Q-See's FREE Dynamic DNS Service (DDNS):
Save the additional cost to switch from a Dynamic IP to a Static IP in order to remotely monitor your DVR. Q-See's FREE Dynamic DNS service (myq-see.com) allows you to easily access your Q-See system without having to remember the IP address, even if it has been changed by your ISP. Q-See's dynamic DNS service is FREE with every Q-See DVR - never pay extra.

Universal Plug and Play (UPnP
): 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 the DVRs to automatically 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!

Convenient Backup: Backup video files from the surveillance system to a PC, Flash Drive or USB Hard Drive in order to free-up space for new video while retaining important footage.

Navigation Menus: The user-friendly interface, along with the accompanying mouse and remote control, make navigating through the program menus a breeze

*Always verify the specifications of each DVR, as not all DVRs come with the same features.

Peace of Mind - Anywhere, Anytime.
