Siren is Uniden's long awaited scanner control app for the BCD536HP. The app allows you to listen to and control your scanner over a wifi link -- either a direct link to the scanner (useful for mobile applications) or over a local intranet connection.

V1 allows monitoring and control in scan mode. Future updates will continue to add more capabilities to the app.

Your scanner must be running the latest firmware to use this app. For information about the latest firmware, see

Works but needs major work

The app works when the iPhone and radio are connected to the same wifi or when iPhone is remote but connected via VPN to the network that the radio is on. The audio is very flaky though. There is a problem with extreme low volume on bluetooth connected devices. And, if the app is started with headphones already plugged in it still outputs to iPhone speaker instead of to the headphones. Also, Unit IDs are not shown on the app display even though they are set to display on the radio. Come on Uniden, an update to fix these bugs is needed.

Development Halted

Hasn't been updated in over a year. This is barely useable and appears to be a beta version. Only works over a LAN - trying to forward over the Internet (using DMZ or a VPN) results in telemetry, but no audio. The audio is a good 3 seconds behind the data on the screen, replay / recording don't work right, no way to remotely reset the radio, app doesn't close properly, it's just a beta proof of concept to be demoed at a trade show - can't be used in real life. There are much more mature remote control s/w apps out there that do this same thing a lot better. I bought this radio solely for the EDACS PROVOICE decoding (an extra 50 dollar upgrade BTW) and thought the remote would be a nice touch, but come on! No updates to this S/W since last year? It's vaporware. Thank god it was free.

So far so good.

I just put this app on my iPhone and iPad today and so far it’s working great for me. Took a little while to figure it out but after I connected my BCD536HP to my wi fi then entered the IP address from the scanner into the app it started working!

I can leave my scanner on but my volume all the way down then listen to the scanner in near real time on my phone or iPad in another room or even in the yard. This way it doesn’t disturb the wife when she’s watching tv as my scanner is in the living room.

So far so good.
