Telephone Entry System. Farm Gate Security ?

Edwards Finance > Phones

Q. I am a novice but have electonic experience, not electrical and am wishing to install a Gate Security system. I want to be able to manually open/close gate from the house (400 feet), converse with/see car at gate and provide several wireless units for our cars to automatically open the gate. I perfer a do it yourself method. Any suggestions on books, manuals, internet posts, etc. where I might get purchasing/installations instructions?

A. First and most important question is do you have or intend to install a conduit to gate and is this an existing gate or a future? I might also recommend looking at group (comp.home.automation You could use a telephone entry system which will hook up to its own telephone line (provided you could have one at the gate). It would then auto dial your house number and you could press a key on your phone to open the gate. Wireless from a car is not too easy since most wireless button systems have a very short range. If you have mobile phones then you could get a phone entry system that can dial several numbers (only one at a time) and you can set each number to dial one of the mobile phones. Then the person with the mobile phone can press at key and open the gate. This is an application where I concur that a hybrid RF/wired system will be best. Use coded transmitters to release the gate. A wired video intercom with remote release, such as Aiphone would be nice for visitors. Perhaps a vehicle sensing system such as Cartel or United Security's Vehicle Alert would be a nice addition to this. BTW, if the gentleman has a monitored security system on the home, he may wish to have the alarm system page him so he can activate the gate release when the police or fire department arrives. They usually don't climb over gates (unless they're looking for a missing glove). The easiest solution is to use a standard commercial gate operating device with off the shelf radio transmitters and receivers. Chamberlain/Liftmaster/Sears makes a commercial receiver unit that you can attach a coax cable to and extend the pig tail range for long distance operation. As it stands now, the FCC has severely limited the broadcast range of the transmitters to very close range so if you are looking to extend the range .... extending the antenna is the simple choice. Once you have the receiver you can then choose a wide range of transmitters including a wireless keypad that can be used outside to grant access to guests or visitors with a 4 digit code. We use ours from time to time with a temporary code to allow access to services. I do agree with one of the other suggestions that you do run a conduit to the house - hard wiring the unit does ensure reliable operation. I can offer a few reputable gate operator companies if you should want to pursue the topic further.
