This 4 Channel DVR is our most powerful 4 camera security video recorder that supports HD security cameras up to 4K resolution. You can use any of our 8MP security cameras to record up to 7fps per camera, or use one of our 4MP security cameras to record up to 15fps per camera. By using our HDCVI cameras you can get better video quality than 1080P while avoiding the hassle of upgrading your existing security camera cable. In the past, to attain resolutions of 4MP or higher required using IP cameras, but recent advents in security camera technology have made it possible to send 4MP and 4K video over good quality RG59U coax wire.

In comparison to our other 4 channel DVRs, this unit has a few important features that set it apart from the rest:

If you are unfamiliar with HDCVI cameras, they can send HD video over RG59 siamese cable, i.e. that's the type taken from a spool of wire. They are great for use in upgrading existing systems, or in new systems where the fussy networking required for IP cameras is too difficult. If you are looking for a complete system be sure to check our 4 camera security system.

This surveillance video recorder is a 4K Pentabrid DVR (aka XVR) that supports all the common security camera signal types: IP cameras, HDCVI cameras, and standard analog security cameras. It has one SATA port for one hard drive up to 10TB, and four add-on microphone inputs. Using the HDCVI technology, it can capture audio from our HDCVI security cameras with built-in mic (mentioned above) and the DVR can capture audio from the camera over the video coax cable without the need for an extra cable.

This DVR does not sacrifice on any of the features or reliability that more expensive DVRs offer. You can even use PTZ cameras with this 4 channel XVR. Simply connect the cameras and start recording. You can find compatible HDCVI cameras here, and choose from 720p up to 4K cameras depending on your requirements. If you are unsure which security camera is right for you, don't forget to read our guide on how to choose a security camera.

This 4 channel HD DVR has a high speed processor with embedded Linux operating system that stays free of any viruses or Trojans. It comes with the same great user interface as all of our other DVRs, and uses the latest generation H.265 encoding to record video at great quality while conserving hard drive space.

All of the DVRs we sell include tons of features, most important of which is video based motion activated recording that you can use to save hard drive space and record only when motion is detected by the intelligent software on this DVR. The motion push alerts can also notify you on your phone or tablet when activated, and you can also playback video from your phone or tablet.
