Incorporating Video Into A Single-Door Access Control System, Part One

The BlueWave Security NetGen IP Door Controller makes your favorite electric door hardware manageable over the IP network.


Examples of non-proprietary electromechanical, standalone network locks are the Sargent Profile and Schlage AD locks. Locks that are just locks, not equipped with a reader mechanism, such as electrified cylindrical locks, mortise locks, electric strikes and electromagnets will operate with any type of access control software that has a triggering mechanism.

Two types of input mechanisms are used by access control systems the keypad and the card reader. Card readers are usually designed for a specific application including bar code, magnetic stripe, proximity, biometric or Smart Card. An example is the proximity card that is probably the widest used technology for controlling access and time and attendance. There are numerous proximity card formats; some are proprietary, some are not. To read the different proximity card formats, there are different card readers.

BLUE WAVE SECURITY

At a trade show, I met John Hughes, vice president of engineering and products at BlueWave Security. This company provides electromechanical access control solutions that are not limited to a single vendor’s product line. BlueWave Security produces the NetGen IP Door Controllers, BlueView Pro software to manage access control, and a wireless electromechanical lock.

The BlueWave Security NetGen IP Door Controller is a one- or two-door access control panel that takes your favorite electric door hardware and makes it accessible and manageable over the Internet Protocol network. It runs over an existing Ethernet or Wi-Fi network, or can be installed over a dedicated subnet. The NetGen unit is installed on, and configured for, the network like any computer or printer or other networked device.

Running on either 12 or 24 VDC power, the NetGen IP door Controller uses only about 3 Watts of power (current draw is .260 Amps @ 12VDC). It can connect up to two credential readers using the standard Weigand protocol. It has three sensor Input ports, two alarm Output ports, and two Form C dry contact relays. On-board memory stores the valid credentials along with shift, holiday, command information, and audit trails of recent events at the secured opening. The onboard access control firmware evaluates the presented credentials and makes the decision to Admit, Alarm or whatever is configured.

BlueWave Security also provides software to make managing the Access Control configuration simple. The software, BlueView Pro, is a small application that runs on Microsoft Windows operating systems and uses the freely downloadable Microsoft SQL Express database. It can be configured to point to an existing installation of the enterprise versions of SQL Server for higher performance access control installations. Existing installations run the gamut from one door to hundreds of doors spread across a worldwide retailers’ Intranet. BlueWave Security is associated with Clark Security Products.

For this article, I was invited to an installation controlling access to a single door that incorporated a video camera providing real time video prior to the opening of the door and continuing until the door is closed and secured.

Suggestion: During your preliminary site survey, determine the conditions for running wire. Is there a drop ceiling or accessible attic? Are the walls wood or metal studs or poured concrete? Knowing the installation considerations can determine whether an access control system should be wired or wireless. Most manufacturers of access control systems and electric door hardware recommend a specific size of shielded twisted pair wiring be used to install their devices. We recommend you follow those guidelines. For this site the installer used 18/2 cable for the sensors and locking devices (anything that just needed a contact closure to work) and 24/6 shielded cable for the proximity reader.

The door leads into a secured room at the San Diego branch office of Clark Security Products. The room has a drop ceiling. To simplify running the wires to the power supply, electric strike and the proximity reader, the installer used Fiberglass Push Rods from Labor Saving Devices. These flexible, fiberfuse fiberglass rods are .162” in diameter and allowed him to easily guide the wires through the walls.

Hardware being installed is an:

Altronix AL600 ULX power supply
