Hoping someone might have found a solution to this issue. 


I have my 16CH DVR located in a rack along with other equipment. The problem is that the IR signal from other device remotes switches functions on the DVR. I've tried changing the DVR remote code but this seems to have no effect on the IR codes.  

Is there any way to stop this happening if using IR for control?  Ideally I'd like direct IP control using an app like Roomie. I know I can view the DVR output with an app but I'd like control of the actual DVR using IP.

You can probably stop the behavior by a putting a small piece of electrical tape over the ir receiving window on the face of the Dvr, which would block the signal from remotes entirely. Just use a mouse at the Dvr, and your remote software for everything else.

That won't really help unfortunately. I have the DVR feeding into an HDMI matrix and this allows viewing of the CCTV throughout the property on any TV.  Although the matrix allows discrete IR to be sent to each source the matrix control itself interferes with the DVR as the IR signal sent from each display location to switch sources causes changes on the DVR. 


I have ditched all PCs as well and am only using MACs and iOS devices. I'm already using apps to remote view on an iPad. However this doesn't solve the problem of control when viewing the CCTV on the TVs throughout the property. 


The  only workaround I've found is to set the IR remote code to something different when not using the CCTV and only switch to the correct code when wanting to switch camera views etc. Not ideal but it works.
