    "Blu Eye" police radio detector

    "Blu Eye" monitors radio traffic activity used by emergency vehicles and alerts when they are in close proximity. It does not allow someone to actually listen in on radio transmissions, but alerts to the presence of an emergency vehicle (police, fire, ambulance,etc.) up to 1km away. Made by Target Automotive, the device can detect pulses sent over these channels every few seconds, so it works even when there are no transmissions. $1,600 and only available in the UK for now, but a model for the USA's P25 protocol is on the way.

    I like the idea if they cut the price to about $400. And only if they allow a Bluetooth connection to a smart-phone, WITH an ap that runs in the background and notifies with a pop up window.

    I can see how this could be useful in Europe, where scanners are illegal most places and the radio protocols are encrypted. That price tag is way high, though. In the US you can get a digital scanner for $300 or so and with careful programming achieve the same effect. I was able to hack together a cellphone app using a serial to blutooth adapter that works as you describe:https://www.rdforum.org/showthread.php?t=31131

    I've only had a few successful "close call" hits... just road construction crews and factory maintenance personnel I happened to drive past. Aside from police mobile computers, I'm not aware of any radio protocols that send out "blips" when the user is not actively transmitting. Still a cool idea... got a link?

    Edit: Found it: http://www.target-automotive.nl/en/target-blu-eye/ As I suspected, it monitors the TETRA systems in Europe.

    nice find ^^^^^ Blue! Years ago we had a similar concept incorporated into a CB radio called a BCT( Beartracker). I had one and it didn't work very well. It was supposed to capture those transmissions and then tell you approximately where they were. I'd love it if we had a new digital version that actually worked.

    The blips are the repeaters that the vehicles use to communicate with the body radios the Leo's wear.

    I still have mine, I use it at the NASCAR races I have to go to. The only thing it was good for was listening in on canadian truckers giving out the bear calls on CB, and even that was not that helpful.

    This seems to be the modern take of the Uniden Beartracker technology which, instead of listening for the 4 second Tetra pulses, listened for mobile repeater transmissions. My BCT-7 had this and it worked pretty well. When it picked up the mobile repeater transmissions it would alert with beeps and a flashing red light. You were with a mile or so when it alerted and it seemed to be very effective. When it went off I would come upon an LEO about 50% of the time. No doubt the other 50% were LEO bogies too, just not on the same road I was traveling. Alas, I've pretty much retired the BCT-7 in favor of the PSR-800. But I miss the Beartracker feature. I can't wait to see how the P25 tracker works for the US. ;)


    Cheers.

    My scanning experience is limited to my PSR-800. I am wondering if this EU system can indeed capture the digital trunked systems that most (BUT NOT ALL) Depts. use. If it works as well as the vid (not much distance though??), I'd call it a win for sure!!! You guys with scanner experience, what do you think??

    Some interesting reading on P25:

    https://en.wikipedia.org/wiki/Project_25#Traffic_analysis_and_active_tracking -discusses vulnerabilities in the protocol

    http://op25.osmocom.org/trac/wiki - software defined radio project

    Motorola trunked systems are extremely common in the US. I would think this would also need to be implemented in the US version.

    The "Close Call" feature in Uniden scanners (called "Signal Stalker" on RS/GRE scanners) could work something like this device. You would have to be careful to mask out unwanted frequencies or the thing would be going off all the time. Range definitely will be short (depends on your antenna and transmitter power):

    http://wiki.radioreference.com/index.php/Uniden_Close_Call
    Also see:
    http://forums.radioreference.com/uniden-thread-archives/234971-closecall-range.html

    I think some of the new SDR technologies will go a long way towards solving this problem.

    Our locals mobile computers are cellular. You can see the mifi hotspot mounted on top of their dash. I think the days of police computers transmitting over radio are over. Government cell contracts are cheap and unlimited. You can clearly see their toughbook mounted in the car too.

    This sounds like a really cool idea - I just wander how well it will work due to all the different systems in place here in the US.

    X2. When i was looking for a scanner, I wondered about this. Now we now. Thx PC.

    This is a great tracker and for me it would wonderfull in the desert.

    Target Blu Eye works on 380-400 MHz only.
    But in the near future Target will be able to modify the range.

    PC,

    I used to have a Uniden BCT7, but by the time I got it, LEO's in NJ had switched to a different system and didn't use repeaters. However, on a trip from NJ down to NC via Route 95, the BCT7 was mind blowing....it was picking up State LEOs with unerring precision. A few times I got an alert from the BCT7 and it took four minutes or so before I got lit up with radar. Ah, the good old days....

    If they can keep the price reasonable, this would be a Great supplement to our current CMs . I mean, this is truly the proverbial "cop detector" that we've all talked about.

    Some videos of the Blu Eye are on the net. Maybe its quick examples just for our need for instant gratification, but I am not impressed by this product as shown. The lead time is a second or two at the most, FAR less than a kilometer, more like 100 feet. Its possible the sensitivity is set to City, but its still too little warning time to be effective. If it was a ambulance, you would easily hear the siren long before the Blu Eye alerted you. At least in the examples I've seen so far.

    Funny how big-media and leos are reacting to this product. Anything less than total control freaks them out.

    Update: I couldn't get the video link to load in this thread, but if go to YouTube and do a search for "Target BluEye Signaleert" there is nice example of the product performing as I had hoped. Maybe someone else could get that video to link here. Most of the other videos were just silly, but this one gives me high hopes for Christmas. Plain and simple, this unit needs arrows. For $1,600 it should show what it is (police, fire, ambulance, etc.) and dispense hot coffee as well.

    So true. Of course they don't read the specs... short range, doesn't decrypt the transmission or distinguish between police/fire/ambulance etc. I do think it's a cool toy, not extremely helpful as a countermeasure though.

    I agree. See my post above. I use the PSR-800 now but still miss the BCT-7. It came in very handy! I know the BCT-15 has the Beartracker feature, but it's in a rather large box and I'd rather have it in a standalone radio (or have it programmed into the PSR-800 ;)). Yes, indeed -- the good ole days!


    Cheers.

    Well, it COULD BE more effective in a rural area where there's NOT a lot of activity!!

    Exactly. The Beartracker (BCT) was designed to listen for mobile radio extenders (MREs). That was a good concept because LEOs were the most likely to use them, and the range of them was a few miles. So in a way it served has a "cop detector." With the advent of 800 MHz trunked radio systems, the use of MREs fell out of favor. I have read on radioreference that some 800 MHz trunked systems have returned to the use of MREs but AFAIK it is not that common.

    To optimize Blue Eye as a countermeasure, it would need to limit itself to reporting transmissions just from LE talkgroups. This should be totally possible with P25 systems, but it would almost have to be user configurable then.

    With encrypted systems, I always wondered if it wouldn't be helpful if you programmed a scanner to just monitor input frequencies (mobiles and portables) to the repeater and report transmissions with an audio alert. IIRC, some Unidens will let you swap output with input frequencies when monitoring a trunked system. However, the Unidens will automatically skip encrypted talkgroups so that would rule them out. GREs, like my PSR-500, do not skip encrypted talkgroups so it would be more useful. If you could mute the annoying encrypted audio and just report the reception with a beep that would be a good work around.

    Hey anything that lets me poke my finger in they eye of fully encrypted systems, I am interested!!!

    It would be nice to see this come to and get developed for the US market. The more countermeasures the merrier. :)
