Your DVR may have boot failure issue if any of the following happens:
- LEDs are OFF at the top or front of the DVR.
- LEDs are ON and swann loading page shows but reboots after.
To isolate the issue, consider following the steps below:
- Check the red tag – most of the power adapter included has red sticker along the power cable. See if it has DVR/NVR on it.
- Check the power adapter and its output rating – check the sticker attached to it and look for output rating. Most of our DVR use 12V 2A/2000mA.
- Plug to a wall outlet – to eliminate possiblity of faulty extension cable or UPS.
- Unplug some cables – if you have an ethernet cable or cameras already connected, disconnect them for the meantime. Only leave the power plug and monitor connected.
- Secure connection – ensure that the power plug is connected properly to the DVR and not loose.
- Turn on the DVR – some units may have power switch at the back; ensure that is switched ON.
If you are done doing these steps and the issue remains, get the camera's power adapter and check its output rating.
- If it is similar, use it to power the DVR.

Try to plug the adapter to a different outlet instead. Once the LEDs are ON and Swann loading page only showed once but still not getting the DVR's Menu interface, consider reading this article:
