Abstract

The PC Alert System is an integrated intruder, smoke and flood or water detection system within a single integrated unit that is plugged directly into any Personal Computer (PC) through a connector, such as via a USB cable 4. The unit has a camera 1, smoke detector 2 and flood detector 3. When triggered by detection of flood, smoke or intruder, the user will get immediate notification of activation, such as by a Short Messaging Service (SMS) text message) to the user's nominated mobile telephone number. Images from the camera may also be immediately sent to the user's nominated Email account (see fig 2). When not connected to a PC, the smoke and flood detectors may trigger a local alarm sounder 5 integrated in the unit (fig 4).

Version 5.0 1.0 Title 1.1 The title of the invention is Personal Computer PC Alert System.
2.0 Background
2.1 This invention relates to a PC Alert System which provides an integrated smoke, flood and intruder detection system which plugs directly into a Personal Computer's (PC's) USB.
2.2 Whether leaving the house to go to work, shopping, or away on vacation, people always worry about the safety and security of their homes.
Flooding is also becoming more frequent due to our changing environment and the threat of a break in or a fire whilst away is always there.
2.3 Whilst there are many alarm system on the market -there is no system which provides a means of integrated monitoring for smoke, intruder or flood through a single unit that plugs into a PC directly through the USB (with the added benefit of instant remote notification to the user whilst there anywhere in the world).
2.4 A vast majority of existing alarm systems do not provide remote notification of activation, they simply sound an alarm on the property.
These systems therefore rely on a neighbour or passer by taking action -which sometimes does not happen (particularly during the day whilst neighbours are at work and/or where properties are remote).
3.0 Statement of Invention
3.1 To overcome the problem stated above (2.0), the invention proposes an integrated intruder, smoke and flood detection system within a single unit that is plugged directly into any Personal Computer (PC). When the : associated PC Alert Software is installed on the host PC and the unit is * armed, the user will get (on detection of flood, smoke or intruder) immediate notification of any activation. This will be provided through Short Messaging Service (SMS text message) to the user's nominated mobile telephone number. Images from the PC Alert Systems Camera : will also be immediately sent to the user's nominated Email account. In addition, users will be able to log onto the PC Alert Website and view live * images of their property through the PC Alert Unit's Camera.
3.2 The PC Alert System will allow the user to be made aware of any activation whilst they are away from their home. On being made aware of the event the user can investigate so that the necessary can be taken. The user may decide to investigate by viewing transmitted images from the PC Alert Camera, viewing live images from the Camera and/or contacting a friend or neighbour to investigate. The user then may decide to go home and/or contact the emergency services.
4.0 Advantages 4.1 There are many alarm detection systems on the market but there are no integrated units that monitor for intruder, fire and flooding that plug directly into a users PC (through the USB).
4.2 The PC Alert Unit will be attractive to anyone who owns a PC who wants an affordable, easy to set up means of monitoring their home (with instant notification of any activation) any time they are out of their home. This unit would also be ideal for businesses as a standalone or to supplement their existing systems in order to provide a means of cost effective remote rn on i tori n g.
4.3 The integrated unit (coupled with its plug and play functionality and simple to use PC Alert Software) will mean that the unit is very easy to install and set up. The initial set up of the entire PC Alert System will be below 5 Minutes. From then on any subsequent arming and/or disarming of the system will be a simple click of the mouse through the SMS Alert Software interface.
4.4 The simplicity of the PC Alert system will make it an ideal choice for any one who wants an easy to use, effective way of monitoring their home whilst they are out or away. The remote notification service (which will be effective and affordable) will be a particularly advantage to all users as it will allow people to monitor and/or check on the status of their property from anywhere in the world.

5.0 Detailed Description
5.1 An example of the invention will now be described by referring to the
accompanying description and drawings.
5.2 Accompanying Diagram 1 shows a representation of what the PC Alert System may look like.
5.3 Figure 1 -Camera -The Camera is fitted (in a slightly elevated position) on top of the PC Alert System. The Camera is fully adjustable (fitted to a pivot) in order to provide monitoring of any area within a given room/area.
5.4 Figure 2 -Smoke Detection -The unit has an internal smoke detection chamber fitted with a smoke detector. Any smoke in the vicinity of the unit will be detected. To aid the detection of smoke, slots are located all around the sides, top and the bottom of the smoke detection chamber.
5.5 Figure 3 -Flood Sensor -The Flood sensor will be attached to the unit by a cable (approximately 1.5 -3 Metres in length). The water sensor will be placed (or attached) at floor level so that any flooding will activate the sensor.
5.6 Figure 4 -USB Cable -The USB Cable (approximately 1 Metre in length) plugs directly into the computer. When the unit is armed through the PC Alert Software, any activation of smoke, flood or motion (detected through the Camera) will be triggered to the PC Alert Software on the PC. This in : *** turn will trigger a Short Messaging Service (SMS) to be generated to the user's Mobile Telephone. * *
5.7 Accompanying Diagram 2 is a simple overview diagram which shows all of the PC Alert system and its interfaces. A detailed description of * : operation is then provided below in the remainder of this section. *S S.
* 5.8 The PC Alert Unit (Figure 1) will be placed in the vicinity of the Users PC (Figure 2). The PC Alert unit will need to be placed in a position where : motion of any likely intruder can be detected. The unit also ideally needs *....: to be located in a position which is likely to be in the flow of any smoke * (should a fire occur). The water sensor needs to be placed (or attached) at floor level so that any flooding will activate the sensor. The water sensor should be placed where any likely water flow/settlement will occur in the event of a flood (i.e. on the ground floor and/or an area that has been previously subject to flooding).
5.9 The PC Alert Unit (Figure 1) will be plugged into the host PC (Figure 2).
After installing the PC Alert Software and configuring the unit (delay timer, Mobile Telephone number and Email address), the PC Alert System will be ready to use.
5.10 When the user leaves the property they will activate a simple option on the PC (through the PC Alert Software interface) in order to arm' the system, A configurable countdown timer will be displayed on the user's PC and an audible alert will sound.
5.11 From when the countdown timer has elapsed any activation of the associated devices (Camera Motion, Smoke Detection or Water Sensor) will trigger the PC Alert Unit to send a signal to the PC Alert Software. The software wilt interpret the signal and send it to the PC Alert Website Interface (Figure 3). This Gateway will then automatically (and instantaneously) send the appropriate SMS Message (depending on occurrence) to the user's configurable mobile telephone number (Figure 4). An image will also be sent to the configured Email Address so can be accessed from any PC in the world (Figure 5).
5.12 Activation of the Water Sensor -If water is detected by the sensor, a signal will be sent from the PC Alert Unit to the host PC. An image will also be taken from the PC Alert Camera. The SMS Alert Software will instantly send an SMS text messages to the users configured mobile telephone number. The image from the Camera will also instantly be sent to the users configured email address.
The flood sensor on the unit will remain active at all times (even when the unit is not armed' and/or the PC is not switched on). Therefore in the event of water being detected, the internal buzzer will sound alerting any occupants in the property (SMS Text and Camera Images will not be transmitted).
5.13 Activation of the Smoke Detector If smoke is detected by the smoke detector, a signal will be sent from the PC Alert Unit to the host PC. An image will also be taken from the PC Alert Camera. The SMS Alert Software will instantly send an SMS text messages to the users configured : *.* mobile telephone number. The image from the Camera will also instantly be sent to the users configured email address.
S
The smoke detector in the PC Alert will remain active at all times (even when the unit is not armed' and/or the PC is not switched on). Therefore in the event of smoke being detected, the internal buzzer will sound alerting any occupants in the property (SMS Text and Camera Images will not be transmitted). S...
5.14 Activation of Motion Detected by Camera -As soon as motion is detected through the PC Alert Camera, the event will be immediately * S logged and the image sent to the Users Email Account (this is to ensure that if the activation is due to an intruder, the image will be captured before the computer is possibly disconnected and/or the PC Alert system is seen (and unplugged)). Images will then be subsequently captured and sent to the users configured email account on any subsequent motion detected after the configured delay time.
When then system is armed, it will be possible to log onto the PC Alert Website from anywhere in the world in order to view live images through the camera.
5.15 Loss of communication (through failure, power loss or the PC Alert System being unplugged) will also be detected and reported via SMS text message.
5.16 Activation of any event will result in a image (or images) from the Web Camera being automatically sent to the user's email account -thus if the user receives an PC Alert text message and then logs onto their email account they can view the images (sent by PC Alert) from anywhere in the world. The user will also be able to log onto their account (through the PC Alert Website) and view the Web Camera on their PC Alert Unit any time the unit is in an armed' condition.
5.17 The associated PC Alert Software, which will be installed on the host PC, will enable users to configure the PC Alert System, view all triggered events (alarm and the recorded CCTV), configure the alert Mobile (Mobile Telephone Number and Email Address) and test the system.
