The present invention relates generally to security windows mounted in doors and barriers. More specifically, the present invention is a dual view virtual high security window that is intrusion, fire, bullet, and blast resistant.
School shootings have unfortunately become more common and more deadly in recent years. If an assailant breaches the front entry of a school, the classroom door is the last line of defense for the students in the classroom, and few teachers are equipped to defend and protect students in such a scenario. It is therefore an objective of the present invention to address this issue by providing users with a full-size virtual “window” created by a pair of opposing cameras streaming live video feeds to digital displays mounted opposite each other in a frame such as an interior door that offers positive security against unwanted or illegal forced entry into a classroom, office or the like. It is also an objective of the present invention to provide an information dissemination platform through remote electronic control of any messages or other digital content to be displayed on the digital displays.
It is a further objective of the present invention to provide to provide a high-security door or other barrier constructed to withstand fire and bullet impacts, and whose constituent components are further laminated and encapsulated together with high performance laminate material, providing durability and enabling functionality in a wide variety of challenging environments.
Additional advantages of the invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention.

The following is an alternative, exemplary description of the present invention intended to further illustrate the spirit and scope of the present invention, and is not intended to be limiting.
The present invention is a dual view virtual high security window that is intrusion, bullet, and fire resistant. The present invention uses monitors, a ballistic core, and additional electronic features for installation into doors and barriers.
A 911 emergency button for intercom communications could be integrated for 911 calls to police, school security, admin, teacher, and other designated persons. Such calls may or will be routed through phone lines, two-way radio, or simultaneously through phone lines, 2-way radio, and a police alarm line. An emergency 911 button will serve as a trigger switch for security, police, or to any prescribe user responsible to respond. Once the button is pressed, a person executed the call will be recorded on video, and the door flashing red/blue strobe will flash, the high voltage arcing electrode will start arcing, this will cause a delay to destroy the door lock by the intruder. The call will also activate simultaneously via intercom and 2-way radio so that there will be a redundant route if one gateway fails.
A blue/red strobe light flasher is also integrated to give warning that an intruder is present on a certain door area once the emergency button is activated. Blue and red is the code light for the law enforcer. These flasher lights on both sides of the door will be active once the emergency button is enabled.
One or more motion detectors may be integrated for video recording and light activation if anyone is detected approaching the door within a certain selected distance. The motion detector function may be enabled or disabled at will in some embodiments, and is used to record the moving subject within the selected distance, in addition to being used for power saving and keep the video monitor on hibernate mode when not in use.
A broadband two-way radio and antenna system (VHF/UHF/800 MHz) is used to simulcast the emergency to police, sheriff, security, administrator dispatch, etc. via a 911 call button. The present invention can utilize any existing radio (mobile or handheld) embedded inside and specially wired for 911 dispatch.
A bright LED back up light may be included to light the surface within camera view area during power failure, and can also be used as a regular illumination light during video recording.

A UPS power supply can be installed near the door or remote and capable of back up power during extended time of power failure. Also, the door has an internal lithium ion battery and charging system as an added back up power.
A radio detection unlock switch may be included, which will unlock the door at the entrance during emergency via radio signal on transmit. The internal circuit of this device will activate if radio RF signal on transmit is detected. The circuit will activate on VHF/UHF and 800 MHz bands on close proximity. The circuit sensitivity can be adjusted from 1″ to 12″. The door lock solenoid will open as long as the handheld radio is transmitting near the designated points of the RF device. This is another option for the responders (police, security, medics, etc.) to open the door quick. Must be restricted to authorized person only access.
A Bluetooth transceiver may also be added for whatever purpose it may serve. For example, to serve as an emergency door opening override.
The present invention is based on a with a standard full view 180-degree vision window. The present invention can be a complete unit for new construction, or a retro-fit unit for existing doors. The present invention can be fully contained within the standard door thickness. The present invention can be on or two way. The internal security core can be steel, fiberglass, ceramic, or alum composite as determined by weight requirements. If the building exterior is breached, the present invention becomes the last line of defense. While there are several choices for the core material, the present invention focuses on the CMF, aluminum foam, as it provides high performance and reduced weight. Power for the present invention is low voltage DC. Special inside (protected side), contains the access to the control panel. Electronic components are contained in this security storage area with room for a defensive weapon if desired, and first aid kit. This substitutes for weapon storage. Teacher is not required to carry a gun.
The present invention provides openness, safety, and comfort of a standard glass, door vision window, while protecting against intrusion, bullets, and fire. The present invention is a safety barrier. The present invention can alert the school administration, the school security guard. The present invention can call the police immediately, locates and identifies the specific classroom with a flashing alert signal light and alarm. The present invention allows for voice communication within the room and the hallway. The present invention has battery back up in the event of power failure. The present invention will help the teacher protect students, without the necessity of carrying a weapon. The present invention will provide fire, intrusion, and protection against ballistic attack, up to and including, high powered rifle, 30.06, AR-15, and armor piercing ammunition.
Security admin can open the door via switch lock/unlock feature. A number dial pad can also open and access the door by dialing a secret combination number. A special designed RF detection system switch that would open the door when radio transceiver is located on transmit in close proximity of the designated sensor inside the door. Example a sticker or reflector in any portion of the door indicates the RF switch override.
