Wreless Access Control

I have an application I am trying to figure out. A facility is putting in a gate opener on a vehicle gate and a personnel gate with locking hardware. They want card access for both. There is power available at the locations, but they want the readers integrated, and they want activity reporting to a computer inside the facility. Unfortunately do to the existance of a parking lot, distance, and other underground parts of their operation it is not practical to run a conduit back to the building. Suggestions?

The access control system can be handled. There is still raw earth between the gate operator location and the personnel gate location. Mount some poles, and put the access controller in a large electrical J-box insdide the scondary fence.

The problem comes in getting from there to the building with reporting data in some easy to use format.

What is the distance between the gate and the building? Are there any obstructions between them? What kind of construction is the building and are there interior walls that might block RF data transmission?

There are RF data transmission systems you can use. The choice is going to be determined by the answers above. If it's not too far you may be able to implement this using a simple wireless LAN. That option will in part hinge on the degree of security required and the kind of data being sent. Log data typically won't need much security as it can be limited to sending user ID and time -- no actual codes. Obviously, control signals must be secure.

I was considering a point to point data transmission setup. Use something with lan management and just make a wireless conenction using high gain yagis between the building and the gate area.

But you know how it is. I wanted to see if there was a more complete and elegant solution available.

Same here.

They exist but prices tend to be higher.

You don't mention the brand of access control. Could be important. There are several ways to skin this cat using Schlage Wyreless Access wireless reader interface, Isonas, Brivo, Cypress Computer Systems, SALock (now part of Assa Abloy) and even Linear Access to name a few.

To get specific:

1) If your access controller has RS-232 or 485 you can use the Lantronix WiBox to establish a link.

It's cheaper than Black Box but works the same.

2) You didn't mention distance but you could put the control on the inside of the building and use wireless like this Cypress Computer Systems, Inc. stuff.

3) Use Bosch Access Easy Control (yes you can get it through regular distribution) with an 802.11a or b or g network. Again no computer to mess with just establish the wireless link and you're there.

4) Screw the whole thing and use Brivo. Then the customer can use any computer (with Internet access) they want to link to the source and you don't have to worry about anything other than collecting their monthly payment. Brivo works in all the spots we put it in so far.

Make money just like from a regular monitoring customer.
