ALP heads getting warm

[deano]

just noticed tonight at work ..after all the bosses had gone home we decided to bring in my car listen to some music on a real sound system ....cut a long story short I noticed some dirt on the ALP heads I wiped them with my finger and noticed that the heads where warmer than the car itself... I then went to the LI heads and touched them there stone cold ...the key was on for at least 30 mins and every thing was armed

the heads do not get hot as in you cant touch them burning hot but they are very warm on the top and bottom as if some one had held them in there hand just before touching the heads ....I never had my temputer gun to get readings

the reason I posted this I haven't seen this before and im just wondering the life efficiency on the heads specially on a hot summer days

I may be wrong but they may be designed like this and maybe there drawing more power on standby than any other jammer who knows

I believe I read somewhere that ALP is active all the time, so that they can act as true parking assist.

I know mine beep if I get too close to the car in front of me at a red light, meaning they must be always sending some sort of signal. I would assume a very low powered one.

cheers mate

all of AL products work as a parking sensor full time so its nothing new on the ALP

my g8 and G9 don't get warm

all AL: through a IR camera will show a flash pattern on heads even when there are no lidar Interference

Yes,I've noticed when in STBY (not active defense mode) & viewing w/ IR video cam that there are very brief & very low output "pulsing" signals sent out to check proximity of objects nearby (inside your set-point) getting to close.

Yes, You are all correct. With Parking Mode activated they are constantly monitoring for obstacles which is why they are always warm when on. They were designed this way and its not a flaw.

just never noticed this on the G8 and G9 going to switch off parking mode at the week end this means the heads should not do any thing I will check then unless some one beats me to it

Thermo gunned mine @ 40 degrees Celsius, they have been on all day. I thought to myself the same thing

You must have read my mind lol, something I asked about 10 mins ago lol

905nm is in the infrared spectrum which produces what we sense as heat. This is how in the dark infrared sensors can image heat containing objects. As explained above because the ALP is a parking sensor and is always active at low power, the heads are always producing heat. That is one of the reasons brute force jammer can only operate for a short period of time.

On a good note I can see two benefits from this:

1. If someone asks what they are you can really tell them parking sensors and tell them to go and block a sensor and they will hear the alert go off
2. If you are in a cold climate you do not have to worry about snow and ice building up on the heads and rendering them useless
