Product Description |
|
A car alarm is an electronic device installed in a vehicle in an attempt to discourage theft. Car alarms work by emitting high-volume sound (usually a siren, klaxon, pre-recorded verbal warning, the vehicle's own horn, or a combination thereof) when triggered or when circuit is breached.
Car alarms can be designed to be triggered by vibrations, tilting o f the car (to prevent unauthorized towing), touching the car, the opening or closing of special switches (e.g. door contacts), sensing small but rapid changes in battery voltage (which might indicate an interior light going on, or the ignition circuit being activated), or using volumetric sensors such as ultrasound , infrared or microwave.
Many times a car alarm can be triggered accidentally. This may be caused by the passing of large trucks, the vibration of thunder or people coming into contact with the vehicle, triggering the alarm sensors. Some sensores may need adjustment in order to prevent false alarms.
Since many car alarms are triggered accidentally, most people in American cities are numbed to the sound of alarms, and do nothing to prevent theft. The New York City Police Department claims that car alarms are actually making the crime problem worse (see their booklet called "Police Strategy No. 5: Reclaiming the Public Spaces of New York," City of New York, New York, 1994) because nothing is done about the alarms, the general impression is that no one cares about the neighborhood.
Because of the large number of false alarms with car alarms, many vehicle manufacturers no longer factory fit simple noise-making alarms, instead offering silentbut effective?

Customer Reviews For Car Alarm Remote Start Starter Keyless Entry Ht800d |
 If you only need a starter...... |
| Review Date: January 26, 2010 |
| Reviewer: Thomas W. Kime, Montana |
| originally I only wanted a remote starter and that's all I ordered. Unfortunately they did not have the one I ordered in stock so they upgraded me ,free to this unit, which was very nice of them. the big issue is this unit is very complex and does everything and it was a gift for my 67 year old Mother. So teaching her to use it has been the hardest part. My mechanic complained bitterly about the complexity of installing it and it took him 9 hours to do it. It really is a nice unit if you need all the things it does. |

| A good car alarm, the company provided fast tech support when asked via email. The sensors take a little time to initialize, that took us by suprize, but we got it sorted out on enquiry. |

Hi, I own this car alarm system and it's been working pretty well. it is 2 way LCD paging system as well as car alarm + engine remote starter.
especially, winter time, it really help my smooth riging. the paging system works pretty well, paging distance is quite long.
keyless entry feature is well done by Hutai company.
also owner recogntion feature is one of the fancy feature. it unlock automatically as you approach to your car without pressing the button.
[...]
company are selling at [...] fee in their website, but amazone offer at [...]with free shipping.
I strongly recommend this kit, it's pretty good one.
