More Sirens the Better

This interior siren fits the bill to deter thieves. Nice and cheap too.

DEI 513T Piezo Siren Review

Working with electronics and on cars for years now I have used this item, the 513at Piezo Siren in several cars I have owned. I usually install this siren somewhere inside the vehicle so that in the event the car is broken into, this siren will blast at around 110-115 decibels on a loud continous loop. Just within seconds it should annoy and deter any car thief from wamting to draw attention let alone keep wanting to hear this siren blaringin their ears . I would highly recommend this item for anyone putting in an alarm in their vehicle. Take time in having it installed in a place under the dashboard that would not allow easy access to it.

Great Product

This product worked as stated. It is been six months since I got the product and I haven't had any problems with it. I would recommend this product

Simple, works

a bit of a pain to adjust the sensitivity, (it still warns when a big truck drives by) but very simple install, just one plug and it works. would def. recommend.

worth

very good product. I would recommend this product to anyone as an extra siren as an additional security measure. Buy with confidence

Ouch

This thing hurts when its ringing. I highly recommend it!

loud

I've never installed these but we have them at work if u put one or two in ur car no thief would sit longer than a min cause it would hurt to bad.

worth every dime!

Let me tell you, this siren will cause massive headaches to anyone trying to break in your car. I personally couldn't stand by the hood of my car for more than a minute while it was going off. I have it installed underneath my battery tray facing towards the ground so it'll echo. Well worth the money and time to hook it up. I would recommend this product to anyone as an extra siren as an additional security measure. Buy with confidence.

Great Siren, it's small and easy too hide under the dash, and is ear piercing loud.

Loud and small

This siren delivers a very high pitch sound. Works awesome. This siren size is tiny but loud.

Mini Interior Siren

This siren works alright, it isn't super loud but I like having a backup that would pierce the ears of any intruder inside the car.

Directed 513T Sirens

Good product. Would recommend for security systems where you want lots of nasty noise.

great buy

this is a nice addition t o any alarm system its very loud.just dont set off the alarm while your still in the vehicle lol

Pain generator!

I bought this siren to install under the dash inside the RV. This was to add extra grief to any thief. Hopefully nobody will break in. But if they do it will be loud inside the cab and not pleasant.
