For wireless network connection between DVR/NVR and internet router
Break Free From the Network Cable
Use the USB Wi-Fi Antenna to replace the network cable connecting the DVR/NVR to the internet router.
Going wireless on the network connection lets you choose more secretive spots to hide your DVR/NVR, as it no longer needs to reach the router via cable, making your video evidence more secure.
Add the USB antenna to the following recorder series: DVR-4480V, DVR-4580V, DVR-4780V, DVR-4980V (4 channel) and DVR-4980 (8 and 16 channel), DVR-5580 and NVR-8580. They must firmware version 8 or higher.
