INTRUDER ALARMS

Electronic alarms designed to alert the user to a specific danger. Sensors are connected to a control unit via low-voltage wiring or a narrowband RF signal which is used to interact with a response device. The most common security sensors are used to indicate the opening of a door or window or detect motion via passive infrared (PIR) or/and Microwave or glass break. New construction systems are predominately hardwired for economy. Retrofit installations often use wireless systems for a faster, more economical installation. Some systems serve a single purpose of burglar or fire protection. Combination systems provide both fire and intrusion protection. Systems range from small, to complicated, multi-zoned systems.

Depending upon the application, the alarm output may be local, remote or a combination. Local alarms do not include monitoring, though may include indoor and/or outdoor sounders and strobe lights which may be useful for signaling an evacuation notice for people during fire alarms, or where one hopes to scare off an amateur burglar quickly

Remote alarm systems are used to connect the control unit to a predetermined monitor of some sort, and they come in many different configurations. High-end systems connect to a central station or responder (eg. Police/ Fire/ Medical) via a direct phone wire or GSM dialer, and the alarm monitoring includes not only the sensors, but also the communication wire itself, running a direct line may be prohibitive. It is possible to use a wireless cellular or radio device as the primary communication method.

CLOSED CIRCUIT TELEVISION

It is a system in which the circuit is closed and all the elements are directly connected, probably the most widely known use of CCTV is in security systems and such applications as retail shops, banks, government perimeter observation, etc. The true scope for applications is almost unlimited..

The starting point for any CCTV system must be the camera. The camera creates the picture that will be transmitted to the control position. Apart from special designs such as dome, bullet or boxed CCTV cameras. Boxed cameras in contrast to the rest are not fitted with a lens; the lens is provided separately and screwed onto the front of the camera. Some lenses have varied focal adjustment. Cameras may be used indoors, like Dome Type camera or outdoors, as Boxed type or bullet cameras. When used

outdoor they will always require a protective weatherproof housing. A special type of camera is Pan, Tilt & Zoom units (PTZ), is used to enable the movement of a designated camera remotely via a PTZ Controller. The PTZ Controller unit allows the operator to move the camera up, down, left and right, and also to control the zoom functions of the camera. The PTZ Camera can also be controlled via the mouse on your PC providing the system is connected to your existing LAN. Systems may contain a combination of different type of cameras.

A digital storage system is employed to capture and store the images from cameras. Additional storage systems can be linked to allow additional cameras to be connected. A hard drive is the medium onto which the images are stored. The system can also be linked to an existing LAN (local area network) or connected via the internet to a remote computer, where images and stored images live can be reviewed (internet high speed connections are recommended to ensure a high video transfer rate).

The picture created by the camera needs to be reproduced at the control position. A CCTV monitor is virtually the same as a television receiver except that it does not have the tuning circuits.

FIRE ALARMS

An automatic fire alarm system is designed to detect the unwanted presence of fire by monitoring environmental changes associated with compustion. In general, a fire alarm system is classified as either automatically actuated, manually actuated, or both. Automatic fire alarm systems can be used to notify people to evacuate in the event of a fire or other emergency, to summon emergency services, and to prepare the structure and associated systems to control the spread of fire and smoke.

Magnetic Door Holders Wall or floor mounted solenoids or electromagnets controlled by a fire alarm system or detection component that magnetically secures spring-loaded self-closing smoke tight doors in the open position.

Duct Mounted Smoke Detection mounted in such a manner as to sample the airflow through duct work and other plenums specifically fabricated for the transport of environmental air into conditioned spaces. Interconnection to the fan motor control circuits are intended to stop air movement, close dampers and generally prevent the recirculation of toxic smoke and fumes produced by fire into covered spaces.
There are many types of fire alarm systems each suited to different building types and applications. A fire alarm system can vary dramatically in both price and complexity, from a single panel with a detector and sounder in a small commercial property to an addressable fire alarm system in a multi-occupancy building. Systems have to protect both buildings and occupants.

ACCESS CONTROL

Access control is a system which enables an authority to control access to areas and resources in a given physical facility or computer-based information system. An access control system, within the field of physical security, is generally seen as the second layer in the security of a physical structure.

Access control is, in reality, an everyday phenomenon. A lock on a car door is essentially a form of access control. A PIN on an ATM system at a bank is another means of access control. The possession of access control is of prime importance when persons seek to secure important, confidential, or sensitive information and equipment.

Item control or electronic key management is an area within (and possibly integrated with) an access control system which concerns the managing of possession and location of small assets or physical (mechanical) keys.

Physical access control is a matter of whom, where, and when. An access control system determines who is allowed to enter or exit,

where they are allowed to exit or enter, and when they are allowed to enter or exit. Historically this was partially accomplished through keys and locks. When a door is locked only someone with a key can enter through the door depending on how the lock is configured. Mechanical locks and keys do not allow restriction of the key holder to specific times or dates. Mechanical locks and keys do not provide records of the key used on any specific door and the keys can be easily copied or transferred to an unauthorized person. When a mechanical key is lost or the key holder is no longer authorized to use the protected area, the locks must be re-keyed.
Electronic access control uses computers to solve the limitations of mechanical locks and keys. A wide range of credentials can be used to replace mechanical keys. The electronic access control system grants access based on the credential presented. When access is granted, the door is unlocked for a predetermined time and the transaction is recorded. When access is refused, the door remains locked and the attempted access is recorded. The system will also monitor the door and alarm if the door is forced open or held open too long after being unlocked.

GATE AUTOMATION

Sliding and swing gates, booms and garage door, suitable for residential and commercial use. An automated entrance or access gate is a great way to add beauty and security to your home or business. Our detail work continues with careful installation that guarantees your gate is hung and operates properly taking into consideration all safety issues.

We highly recommend for the safety of you and your family the use of 'photocells' or similar devices to prevent the gate from closing if someone or something is in the way of the gate. A photo eye shoots a beam of light across the gate opening. If the light beam is broken, it will prevent the gate from closing, or it will stop the gate and reverse its motion, if the gate has begun its closing cycle.

SHOP ANTI-THEFT SYSTEM

Electronic article surveillance (EAS) systems are used for inventory control and to prevent theft and similar unauthorized removal of articles from a controlled area. Electronic article surveillance systems allow the identification of a hard tag or soft label within a given detection area. EAS systems have many uses, but most often they are used as security systems for preventing shoplifting in stores or removal of property in office buildings.

An electronic article surveillance system detectable label is attached to every article that is to be protected. When an unauthorized article removal is attempted, the EAS system detects the label as the article crosses the detection zone. The Electronic Article Surveillance system responds to the detected label with an alarm. When an article is properly purchased or otherwise authorized for removal from the protected area, the EAS tag/label is either removed or deactivated. If the EAS tag/label is not removed or deactivated, the EAS system will trigger an alarm
