DVR Security System Review

Here we have another offering from Q-See in the form of the QSD6209 digital security recorder, the DVR supports an odd number of cameras, you can attach a total of 9 cameras to the device and these are connected through its BNC connectors.  The Q-See DVR uses MPEG 4 video compression and video is stored on the internal hard drive.  There is a 500 gigabyte SATA hard drive built in to the DVR so its storage capacity is decent, you do however have the option to remove this if you wish and replace it with another hard drive with a larger capacity.

There is an RS-485 connector built in to the DVR to accommodate security cameras that have built in pan, tilt and zoom functions.  The DVR is compatible with both PAL and NTSC video signals, at maximum the DVR can record video at a pixel resolution of 720*480 in NTSC mode, PAL mode offers a slight improvement to image quality that being a pixel resolution of 720*576.

If necessary you can set the DVR to record video footage 24 hours a day, a better way of ensuring the system records significant activity is to use its motion detection functions to activate and deactivate recording.  The RS-485 connector at the rear of the DVR can also be used for connecting external alarms to the DVR and it will begin recording should it detect an attached alarm has been activated.  You also have the option to set a schedule that determines when the Q-See DVR will start and stop recording.

At maximum the DVR is capable of recording video at a speed of 60 frames per second, the recording speed of the system lowers slightly when using PAL video signals.  You can select one of four preset image quality settings and these range from low, normal, high, and higher.  You can set up a two way audio system with the DVR but you can’t record audio from all attached cameras as it only has one audio input and one audio output.

The systems built in Ethernet port enables you to connect the DVR to a computer network, this gives you the option to turn computers attached to the same network into fully functional monitoring stations.  You can also connect the DVR to the Internet and this gives you the option of monitoring attached surveillance cameras while you are away from your premises via Internet Explorer.
