24/7 Business Access & Control

Nothing is more vital to the health of an organization than making sure that its people, material assets and operations are safe and secure. GHS’s access control solutions (manufactured by Kantech) address the full scope of risks that might arise, including risks that other devices in your security system (such as burglar alarms and intrusion detection devices) simply are not designed to handle.

GHS Utilizes State-of-the-Art Access Technology & Equipment


Proximity Card/Readers & Pin-pads

Proximity readers continuously transmit a low-level fixed radio frequency (RF) signal that provides energy to the card. Once powered, the card transmits the code to the reader in microseconds. The big advantage of proximity over other technologies lies in its simplicity. There are no moving parts, no mechanical wear, no slots, and no read heads to maintain.


These commercial and industrial rated door strikes can withstand the traffic involved with access control applications. And the solid construction electromagnetic locks will provide years of maintenance-free operation.

Access Control Kits

Choosing an access control system doesn’t have to require hours spent sorting through hundreds of software, hardware, and reader offerings. GHS’s Access Control Kits include all of the components you need to get up and running quickly and easily.

Frequently Asked Questions

The selection of reader and keypad combination affects the level of security at an entry point.

Keypad Only

A keypad only installation is generally considered less secure than a reader only installation. The reasoning is that users may illegitimately “lend” their codes to another person but cannot prevent further use (in comparison to getting a card back) unless the code is changed. Moreover, a user’s code can sometimes easily be visualized and duplicated.

Reader Only

A reader only installation is the most common application but can be susceptible to illegal entry by a person who has found a card outside the protected site, such as in a parking lot or in public transport. Readers outside of a building may be more exposed.

Reader/Keypad Combination

Adding a keypad to a reader significantly increases the level of security. The user is now required to provide both a card and a keypad PIN code (Personal Identification Number). Optionally, the PIN code requirement can be scheduled for use only outside hours rather than during high traffic hours.

Long Range Proximity Readers

The most common uses for long range proximity readers are for parking entrances and per handicap facility requirements. Although several users request long range proximity, they are seldom informed of the actual “side effects” of these expansive readers. For an example, a long range reader installed at a door in a corridor may read the cards of any users walking by the door who do not have any intention of unlocking and entering that door. The door will actually unlock, and remain unlocked for a preset time, without the user’s knowledge. Here is another situation that happens frequently at a door: several users are outside the door having a discussion and finally, one user goes in. Chances are that the system may erroneously report the user having already entered. Therefore, make sure that readers are properly installed to prevent such instances and that a voluntary action from the user is necessary to unlock the door. In most cases, you may revert to a 10 cm (4 in) reading range! As far as parking lots are concerned, there are other alternatives with wireless fobs and vehicle tags

Exit Detector

The purpose of an exit detector is to detect an individual’s legitimate exit through a supervised door. The detector must capture the individual’s hand movement towards the door handle (or panic bar) and, prior to the actual opening of the door, warn the system of a pending exit. When the door opens, the system is able to discriminate between a valid exit and a forced entry. The exit detector can be used on both free exit and controlled exit doors. The exit detector provides automatic and hands-free operation.

Exit Button

The exit button can replace the exit detector on controlled exit doors. The user is forced to press the exit button to actually unlock the door. Exit buttons cannot be used on free exit doors because if a user opens the door without pressing the button, a door forced alarm will be generated by the system.
