What DOC stands for?
DOC stands for Dorlet On Card and is a Dorlet propietary technology that allows controllers and locks working without network connection while still being part of the security system using the same cards, software and access rights as the online systems.
When we use DOC technology?
DOC technology is used when an access must be controlled but there is not network deployed, or the cost of connecting that location is to high, the location is remote or when interfering with stand alone systems.
What devices are compatible with DOC?
All Dorlet controllers are compatible with DOC technology. All controllers have network connection but in case there is no network available the controller can be set in DOC configuration. If in the future the network is available, the controller can be set back to work with network.
DOC stand-alone products such as locks, cylinders and lockers locks are also compatible with this technology. Unlike the controllers, the stand-alon devices doesn't have network connection and are designed to work with DOC.
How does it work?
In a normal online controller the rights (cards allowed, time/day allowed, etc...) are stored inside the controller memory and any change in the rights are send directly to the controller through the IP network.
In DOC devices the rights are not stored inside the device memory as there is no network to communicate it, instead the rights are encoded inside the card. Once the card is read by the DOC device, this one decides if the card possess the necessary rights and if yes, it will allow the acces.
The DOC device also writes inside the card the access transactions and other information. If the card is read using the card encoder, all information stored in the card by the DOC devices will be uploaded to the server, keeping track of all movements, events and transactions in DOC devices.
Advantages of DOC?
-Remote sites without network can be also controlled.
-Stand-alone locks and lockers are now part of the security managment system sharing the same card and software.
-The user will use his card indistinctly in both systems without notice any difference.
-All rights, for online controllers, DOC controllers and DOC stand-alone devices will be managed from one and unique security management system.
Limitations of DOC?
The only limitation of DOC technology is when is used in controllers. A controller set in DOC loses the online communication and therefore it wont be able to send the online status of the door or any other alarm.
To store/update the rights inside the card and to download the transactions contained inside the card, the card must be read by a card encoder connected to a workstation, so it means that it needs physical access to the card. This can be a problem in large projects with large amount of users/cards, to solve this DORLET has available SYNC technology that allows the cards to be automatically updated in any online controller.
Are DOC devices really offline?
We saw that a controller without network and stan-alone locks don't have online connection to the server through ethernet but it doesn't mean that there is not communication.
The card acts as a data carrier sending data to/from the server to/from the DOC devices.
So we can say that DOC devices doesn't have instantly online communication but it has non instant communication through the cards.
