Our 4-channel security DVRs enable video from four surveillance cameras to be recorded at the same time. A 4-channel security DVR recorder is ideal for home or business surveillance, and comes with H.264 compression and motion detection recording to maximize the amount of video you can store on your hard drive. Each security digital video recorder lets you export your video via USB, to your network, or via DVD burner, so you can easily back up your evidence. All DVR recorders feature multiplex operation so you can record, live view, back up, and play back video at the same time. Our security DVR recorder models can be added to your network, so you can easily access your security camera system over the internet or from our free smartphone app from any location.
