DVR Security System Review

Here is another Clover DVR designed for recording surveillance camera footage, the CDR4170 accommodates up to four surveillance cameras, these can be attached to its BNC connectors.  There are also 4 Din video inputs built in to the system, Both PAL and NTSC video signals are supported by the Clover DVR and it uses MJPEG compression.

In NTSC mode the DVR can record video at a maximum pixel resolution of 720*480, in PAL mode the maximum resolution is 720*576.  You can record surveillance camera footage that plays back smoothly as the Clover DVR has a maximum recording speed of 120 frames per second.  The recording speed is adjustable so you can set one camera to record smooth video footage using a high frame rate (eg:-30 FPS) while another attached camera records video using low frame rates.

If necessary you can set the DVR to record video 24 hours a day or you can devise a schedule that determines when it starts and stops recording.  The DVR has motion sensor capabilities and can be set to start and stop recording when motion is detected.  There are four alarm inputs built in to the DVR and the system will start recording security camera footage if it detects an attached alarm has been activated.

Video is stored on the 160 gigabyte hard drive built in to the system, this can be swapped if need be for a hard drive with a larger capacity.  There are 2 internal hard drive bays inside the security recorder and there is a built in USB port you can use for connecting memory cards, external hard drives or other storage devices to the system.

It would have been nice to see a few more audio inputs built in to the system, it has one audio input and one audio output, you can set up a two way audio system with the DVR but if you want to record audio with all attached surveillance cameras your out of luck.  An Ethernet port is built in to the system so you can connect it to the Internet or to a local area network so you can set up additional monitoring stations throughout your premises and monitor the system remotely.
