The DVR can be connected to a monitor or HD television screen to view the images. A power supply provides power to the cameras. The cameras are connected to the DVR by means of cables. Wireless connections are available where line of sight is possible. If a network cable connects the DVR to a router (With a ADSL/LTE/3G connection), the DVR can be viewed via internet.

Live footage of what is happening at your home or business can be viewed from your smartphone and/or personal computer at work after the correct setup. It is possible to have remote access to all the features of the DVR.
