No Alert from LI

[spider_55]

I finally encountered 2 laser hits today, and I get full blast alert from my STi-R and absolutely nothing from my dual Laser Interceptor. Not a warning, gun detection, nothing...

I could see the LEO shooting out of his window and got the alert from the STi-R and was just waiting for the LI to speak. I turned it off, then on again to see if it needed to be restarted and all I got was "Welcome".

I can set it off with an iPOD remote control and get "unknown gun", but the real thing gave me nothing. I am very disappointed with this outcome. I am just glad I wasn't speeding. I waited months to get a chance to run into a laser trap. I found two and the only alert I got was from the Sti-R.

Any suggestions or reason why?

Driving into the sunrise or sunset?

How close was the encounter?

He would have gotten the "Interference from sun is detected....etc."

OP: How is the battery in your car? Is it old or new? Are you power and ground connections solid?

I don't know what version your CPU is, mine is 7.05 with TS. When I activate the system, it says the "welcome" and after 10 seconds it should say "parking aid is..." etc.

2. Another question, did you make any modifications to the unit via the software? Did you remove the jumper on the circuit board at all?


3. Are you getting any warnings about heads connectivity errors?

I feel that if you can rule out all these, you might have a defective unit.

I'm sure LI USA will chime in here shortly to assist.

Only if that feature is enabled at the CPU. Not all of them are.

How close was the encounter?

-- I was driving into the sunrise
-- 200 ft all the way to the LEO
-- version 7.08

OP: How is the battery in your car? Is it old or new? Are you power and ground connections solid?

-- New car. Battery is good

2. Another question, did you make any modifications to the unit via the software? Did you remove the jumper on the circuit board at all?

-- Yes, I modified the software settings.
Parking Aid is OFF, the Parking Switch is DISABLED and the SIA is OFF
-- No, I didn't touch the jumpers

3. Are you getting any warnings about heads connectivity errors?

-- Nope, just the welcome message. No warnings about sensors.

Even if the SIA is disabled and there was an issue with sun interference, wouldn’t the LI still tell me the gun that was shooting? I got nothing...

No. If you're getting sun interference, the sensors are blinded and cannot receive the laser shot. If the SIA is disabled, it can't tell you that it's blinded.

Another close-up shot too! Take that, all you non-believers who think a jammer that protects you down to 500 feet is "ticket saving performance"!

Ok, that's why you aren't getting the parking disabled warning...

SIA is the sun warning right? Could it be it was interfering right when you were being target? It is possible.......

I would turn the SIA back on.

How loud is your car? (Road noise, exhaust)

By the way, are the heads clean?

How are your heads installed? Maybe something with your install isn't quite right...

I'm starting to gravitate towards one of the following:

1. Something wrong with your install. (head alignment or positioning)

2. You did not hear the internal speaker warning when the unit went off. That's common, which is why I highly recommend an external speaker.

3. Your heads were getting interfered by the sun the same time you were being targeted.


Also, you mentioned you have been waiting for a laser encounter. I think you should get your setup tested with a real laser gun. Imagine what would have happened if you were above PSL.......

+1000, thank you, enough said.

OP: turn on the SIA back on and get your setup fully tested.

Are you sure you were the target? My Sti-R is the most sensitive lidar detector I have ever seen. I got a lidar alert on the STi-R the other night, slowed saw LEO shooting out of window. Blinders never went off because he was shooting the car next to me.

LEO pulled out and grabbed him. Is it possible the STi-R was picking up a shot someone else was taking?

Thats exactly what I was thinking too. The STi-R, just like the STi, has four front IR receivers which look like 5mm diameter clear LEDs. The center two IR receivers face straight ahead, and the outer two IR receivers are angled 30 degrees to either side of straight ahead. Thus the STi and STi-R are very good at detecting way off-axis laser shots, and they are fairly good at detecting laser scatter off of a nearby vehicle which is in an adjacent lane of travel.

The LI's laser detection is fairly good, and the LI will definitely detect any laser shot which directly targets your vehicle, assuming that strong sunlight interference isn't a problem at the time. Yet in the OP's case, I suspect that it was a nearby vehicle which was targeted and that by chance one of the STi-R's outermost IR sensors just happened to be pointed either in the direction of the laser gun or at the adjacent targeted car.

I plan to do some fairly crude laser jammer sensitivity testing at the next Atlanta Jammerfest. So, when you see the results, take the results with a grain of salt.
