Part of our troubleshooting when solving Video Loss issues (or some cameras are turning off) is identifying if the power is the cause. Before you proceed, ensure that the power adapters are plugged to a socket (preferably a wall outlet).
Once done, we can now check the output rating* of each power adapter. The power adapter of a DVR and add-on cameras (model number starting with 'PRO') are interchangeable as long as they match the power requirement of each device.
DID YOU KNOW?
- 1000mA = 1A
- A 4-camera DVR kit comes with two power adapters, both having 12V 2A which are interchangeable;
- An 8-camera DVR kit comes with three power adapters, all having 12V 2A output rating with two 4-way splitter as one adapter can support up to four cameras.
- A camera can operate between 12V 1A-2A
- DVR needs an output rating between 12V 2A-5A.
In the diagram below, both adapters have a 12V 2A output rating which means you can swap the adapters. Keep in mind the connectors of each power adapter as some DVR systems are using a different connector.
How to swap
- Check the output rating of the camera power adapter in volt (V) and ampere (A) or milliampere (mA) (e.g. 12V 2A or 12V 2000mA).
- Check the output rating of the DVR power adapter (e.g. 12V 2A or 12V 2000mA).
- As long as the output rating of the camera adapter is within the operating range of the DVR (shown above) AND the DVR power adapter to the camera's range, then you can swap the adapters.
- Unplug the power adapter from the splitter and connect it to the DVR.
- Unplug the power adapter from the DVR and connect it to the power splitter.
NOTE: If you have eight cameras, you can also swap the cameras' PSUs as long as both power adapters have the same output rating.
TIP: If performing the above troubleshooting for the Video Loss issue, please go ahead with BNC extension cable swap troubleshooting if this doesn't fix the problem. You can also connect your BNC extension power cable directly to the power adapter to check if your extension cable is faulty or not.
