front gate automation, which hardware

In attempt to catch the mailbox smashing hooligans that were driving me crazy I became infatuated with everything home automated.

I prefer to stick to linux purely because of

a) I know it's stable and 99% runtime is easily achievable
:) I can easily customize it to do anything I like.


For my CCTV system I have chosen zoneminder and an 8 input video input card from blue cherry running on Ubuntu linux. I have one camera going by the road for the mailbox vandals and will be mounting 2 in my barn for monitoring horses. But I will have the option to expand later.

I will use a few x10 devices for light control, etc... because I'm cheap and don't want to do extensive rewiring. I don't trust wireless and my house and property are too spread out anyways.

The central server location will be in my house. I would like to add an Elk M1 system for security and perhaps to handle some of the automation.

That said, the camera in the barn is about 300' from my house and the camera at the road is 300' in the opposite direction.

For these cameras I plan on running video baluns as it seems like the most economical solution for that distance.

Here is where the automation kicks in. I want to change the locks on the house to keypad entry. Nothing fancy, something similar to the ones you get at home depot. I know I can tap into these to send a lock/unlock signal quite easy.

What I'm not sure how to do, is the next part. I have a front gate with an opener and closer. I want to put a keypad at the gate, so when someone enters a pin number it sends it to the ELK/Computer, checks against the code and then executes a script. If the pin number belongs to the barn staff, it opens the gate, logs the time and makes an announcement. If the pin number belongs to me or my wife it opens the gate and sends the unlock command to the house door locks, unarms the Elk, etc... all before you get to the house.

My question is this, what keypad do I choose for the road that can send a signal to the misterhouse or elk and what should I use to send that signal? Is there an X10 device? Perhaps a keypad over ethernet device, or even a compatible outdoor keypad for the elk system.

I can use the Elk or Misterhouse to sort the scripts. Whether it be Misterhouse telling elk to disarm, or Elk telling mr house to send signal to unlock the doors. I just can't seem to find the keypad hardware for what I want to do.

Programming isn't a serious issue, but I can't seem to find the hardware.

Cliffs:
1) I'm setting up my smarthome with misterhouse, zoneminder, Elk
2) I need a keypad at the gate which checks the pin with the Elk/Misterhouse and issues scripts
3) the scripts unlock the house, disarm everything before you get to the house
4) what hardware do I use?
 
tough crowd....

anyone have any ideas? even a guess to send me in the right direction... hours of googling and I've found nothing that I think can help...
 
Welcome to CT!

The M1 supports executing certain rules depending on who is 'authenticating', so I don't see why you can't use one of the outdoor rated Elk compatible keypads that places like AutomatedOutlet.com sell. Since it sounds like you have Cat5 in place, which will work perfect with Elk compatible hardware.
 
There was a post here on keypads recently and I believe one was outdoor rated. I'm trying to remember the details, but I believe one was RS-232 interface and the other contact closure (when correct code was entered). You would probably want the RS-232 one. I'm not sure if Elk makes keypads that are weatherproof for the gate area.

Reading your post I wasn't sure if you had wiring to the keypad location (you said you wanted to "send a signal", wired or wireless?).

The other problem is your distances concerning X-10 (which is not that robust to begin with). Are all the circuits on the same breaker feeds? Do you have a coupler/repeater? Can you perform a simple test with an appliance module and mini-controller and see if a signal will get from your house to barn?

I believe the Elk can handle all your needs, the problem is the distances that the peripherals have to cover.
 
thank you very much for your replies. Automated outlet seems to have a good selection of devices.

I don't need to control much in the barn using X10, mainly the house.

The front gate however, the only device I want to control is the gate. Although using an x10 device would be easiest, I could use another controller to switch the gate relay. I'm still in the process of setting up the gate system before I can test for x10 signal out there. It is just one breaker for the gate and the camera is powered over ethernet by a balun. But I can pull as much cat 5 or anything else out there as I need. I have a 3" pipe with lots of room left inside.
 
The Elk M1 has an on-board relay, plus other outputs that can control external relays. You can also get a relay module that runs off the main data bus (such as extenders, keypads, etc...).

You can use that to control your gate providing a "contact closure" will suffice for this purpose.

May I ask how you are going to do this? I would be interested in dong this myself.

it depends on the lock, but the one I took apart was very simple


once you enter the correct pin number, it basicaly signaled one contact to unlock the door. If you pressed a lock button, it signaled the door to lock

so basically it's just a matter of grounding out the right contacts.

Depending on which route I go, ELK rule or serial device I will do this with a simple relay
