optional sensors?

I've read in some forums that when installing a DEI alarm to choose and install 2 of these:
- glass break
- tilt
- 2-stage shock (AU84TA)

I'm ready to install this alarm (Cliff IG 770) with backup siren and battery. But I need some help comparing these 3 sensors (are there others recommended?) and why I should choose one or the other (or the other ;-) ).

The alarm comes with a "Clifford Omnisensor" (shock sensor). It's a little larger than an ice cube, black (no part number). Is this not a good one?

Any experience, comments, good and bad, welcome.

Thanks,
JJ

And why only 2 sensors? Why not all 3?

JJ

The only sensor worth having is the G5 digital dual zone proximity.
It will warn away before the others and is remote adjustable.
With the omni, that's really all you need.
The others are expensive overkill and prone to falsing.
Tilt; early versions were extremely prone to instant falsing.
You're better off with a good set of locking wheel nuts.
Glass break, absolute waste, the dual zone proxy should have already warned away.
Shock, why when you already have an Omnisensor.
In fact and this is the point, when properly set up, (I used to drive the car slowly into a mattress, a friend who was a techie at Clifford would hit the Omnisensor with a rubber hammer) it acts as a glass breaker, and shock sensor anyway.

Won't this get falsed by pedestrians walking on the sidewalk right next to the car?

The omni is not a proxy sensor, it's a shock sensor:

Clifford sensors

I think you mean to say that the G5 dual-zone proxy is the only sensor you need, yes?

Thanks,
JJ

Yes, because as you rightly said the omni is simply an extremely sophisticated shock sensor that will suffice (with the possible exception of tilt) as a sub for both shock and glass break.

I'm confused.

Are you saying keep the omni and add the dual-zone proxy?

Or ditch all sensors except the proxy?

Thanks,
JJ

Keep the omni.
Add prox, the G5 Clifford, NOT the 508d.
Possibly tilt.
What vehicle, make and model?

'89 Camry LE.

Not valuable, but mine and I keep tools in the trunk (stolen once).

It's #3 on the FBI most-stolen list not for value but because it's easy for punks to steal (with just a screwdriver!).

jj

Ah, someone with my lifestyle! Owned a couple of Maxis and Camrys, great for discreet tool storage.
Can you get Yale type trunk locks in the US? Bit obvious but more secure.

Like this?

ABUS FTW.
My first ABUS was the diskus series. Decades of motorbikes, mud, beach, abuse and she still works fine.
With their "ungripable" body and 8-tonne rack force, they or not easy to ope without a key. (As my mate found when his Yale imitation seized within a year LOL!)

And though ABUS is "new" down here, IMO they are penetrating fast. My new workplace has them everywhere (import containers & quarantine).


And nice to hear Howie's thoughts. I crack up every time my car sets off someone's "window" sensing alarm (I thought only loud Harleys did that!).
[I use switches & uWave (proximity), and NEVER voltage, glass or ultrasonic sensing.]

JoJo, nothing like that, it flushes in the trunk lid. I thought of Yale 'cause I was trying to think of a lock company also known in the US.

Can you link to a photo or page selling these?

BTW I'm considering shaving the trunk (boot) key lock altogether and doing only keyless. I'll have a backup plan of hidden wires for the actuator and a back-backup of a pull cable (will have to cut some sheet metal to access that one).

It's actually a toolbox on wheels. Drills, meters, small oscilloscope, etc. Trunk security primary priority, and towing security second. (That's why I think I want to add a tilt sensor.)

Yes I could get a van (lorry) but that in itself advertises "TOOLS! STEAL ME!". I like the stealth of a car trunk.

Thanks, jj

A tilt sensor is useless unless the car is jacked up as in removing wheels.
Unless you're extremely experienced or there's an existing electric trunk release, don't bother making it work correctly requires the patience of Job.
I did Google Yale Vehicle locks and got nowhere, meet me halfway and do some of this yourself, nothing installed for two posts and about 3 pages so far.

A tilt sensor is no good in a tow-away attempt?

If you mean that I've done no installing yet, that's by design: only fools rush in without a full plan.

If you're done answering questions I won't blame you. Thanks for your help.

JJ

Of course, anything that raises the vehicle but seriously start installing and by all means ask questions, you're still in the blue sky stage!

Speaking of tilt sensors, DEI makes 2. Both are called 507M but look completely different:

this one

and

this one

Which one do I get if I order the 507M. Is one an early design and one a later one?

Thanks, jj

Never seen the first one before.

Just been on the Directechs site, I think the first photo is a mistake, they've only ever listed the second shape.

And same issue with the proximity sensor:

jj

Oh, I see there's 2 different p/n's for those:

the first is 905311, the second one is 508D.

Which one is recommended?

Ah, thanks. I'll order the 905311.

Just out of curiosity, why that one and not the 508D?

On cars with proximity sensors, are cats a problem setting off the alarms?

I frequently have cat's footprints up the windshield and we all know they love to sit on the hood of the car at night because it's warm.

Are cats a problem?

Thanks.

Because they are made for each other and you can adjust it via the remote control.

Mount in the roof lining with the embossed label facing into the car.

Anything that has mass can be a potential problem. The larger the mass the farther it can be detected, depending how the sensor was adjusted. Many times heavy rain can set it off. So cats may set it off if they climb on your car. When I usually install them, I install a toggle switch so it can be turned off, if necessary.

Edit: as howie said, you can always install it in the headliner. It helps but still has the potential of falsing.
