How to fix no signal on my Smartwares WDVR740S?
- GgkingAug 1, 2025
If your Smartwares DVR shows no signal or video, first, check the power adapter and power cord connection. If that doesn't work, unplug the camera power and plug it back in to reconnect it. You might also need to relocate the DVR or camera for better reception. Consider adjusting the antenna or using a proprietary extension cable with a high-gain antenna to improve the range. Finally, remove any major obstacles between the cameras and the DVR, such as water tanks, metal surfaces, or brick/marble walls.
