This 8 Channel DVR is compatible with a wide array of camera resolutions and signal types. It is a powerful hybrid DVR that supports up to 4K security cameras over RG59U coax cabling. Even if you have cameras purchased elsewhere, you can use them with this DVR as long as they meet the resolution and signal types supported by this DVR. This 4K security DVR supports a combination of five security camera signal types, which can be found here. These five types include HDCVI, TVI, and AHD coax cameras that can send high definition video over Siamese security camera cable. You can also use IP cameras purchased from CCTV Camera World to setup a hybrid security camera system consisting of coax BNC cameras and network cameras.

As explained in our Security Camera Buying Guide, in the past IP cameras were required if you wanted resolutions greater than 1080P. That is no longer the case thanks to HD security cameras over coax, which make it possible to send 4MP or 4K video over good quality coax wire. HD over coax cameras are great for use in upgrading existing camera systems or in new security systems where you want to avoid the complicated computer networking that's associated with IP cameras. If you are looking for a complete system, be sure to check out our security camera systems page.

This 8 Channel 4K Security DVR is one of the best the security industry has to offer at this time for a small form factor with one hard drive slot. It can accept a total of 16 cameras (8 BNC Cameras and 8 IP Cameras). It allows the use of 5 different types of security camera technologies:

  • Analog Security cameras up to 960H resolution - old security cameras will work.
  • HDCVI cameras up to 8MP on any BNC input on the back of the DVR
  • AHD or TVI cameras up to 8MP on the BNC inputs
  • IP Cameras up to 8MP 4K Resolution. Using IP cameras requires a PoE switch to network the cameras with the DVR.

Take advantage of the selection of 8MP 4K HD Coax cameras listed below with this 4K DVR!

This 4K Security DVR supports a lot of different recording configurations.

If you connect the DVR to a PoE switch, you can also connect up to 8 IP cameras from CCTV Camera World along with 8 BNC cameras. By disabling the BNC inputs, you can also set the DVR to record IP cameras across all 16 available channels, making it essentially a NVR. In this mode, the DVR will support a total of 128 Mbps of network camera encoding bandwidth.

It supports one hard drive up to 16 TB, providing plenty of storage space for recording footage.

This 8 channel XVR has a high speed processor with an embedded Linux operating system that stays free of viruses. It comes with the same great user interface as all of our other DVRs and uses H.265+ encoding to record video at great quality while saving up to 50% more storage space compared to regular H.264.

It does not sacrifice any of the features or reliability that our larger, more expensive DVRs offer. You can use PTZ cameras of either HDCVI or IP camera type with this DVR. You can also add our security camera with built-in audio across all BNC channels or our IP cameras with built-in mics.

The XVR allows its users to take advantage of cutting-edge AI Smart Detection analytics such as Smart Motion Detection, Digital Tripwire, and Intrusion Detection on the BNC cameras that are connected. You can choose one AI event detection method per channel on up to 8 of the BNC channels.

The XVR allows for Tripwire and Intrusion Detection features, enabling you to optimize video event detection using the advanced AI technology built into this DVR. Alternatively, you have the option to use Smart Motion Detection for up to 8 channels, which excels at identifying humans and vehicles while ignoring irrelevant objects like leaves, insects, or shadows compared to traditional video-based detection. The XVR is compatible with the Avalonix Premium Series IP cameras and supports video analytics across all IP camera channels as long the camera offers analytics.

Additionally, the XVR provides Face Detection support for up to 2 BNC channels, allowing the system to identify and record faces within the camera's field of view. This added feature enhances security by making sure critical events are documented in areas where people have to pass through entrances, exits, or specific pathways. To effectively capture a face, it should occupy at least 50% of the camera's field of view.

Either motion or smart detection can be set to notify you using a push alert to your mobile device when an event is detected, and you can also playback video from your phone or tablet.

With your purchase, you'll receive free technical support for the life of the product, as well as FREE iPhone, iPad, Android, and Windows/Mac apps. Check out our apps in action here.
