A  public address system  ( PA system ) is an electronic sound amplification and distribution system with a microphone,  amplifier and loudspeakers, used to allow a person to speak to a large public, for example for announcements of movements at large and noisy air and rail terminals or at a sports stadium or amplify other audio content, such as recorded music or the live sound of a band. The term is also used for systems which may additionally have a mixing console, and amplifiers and loudspeakers suitable for music as well as speech, used to reinforce a sound source, such as recorded music or a person giving a speech or distributing the sound throughout a venue, building or area. Simple PA systems are often used in small venues such as school auditoriums, churches, and small bars. PA systems with many speakers are widely used to make announcements in public, institutional and commercial buildings and locations, such as schools,  stadiums and large passenger vessels and aircraft. Intercom systems, installed in many buildings, have both speakers throughout a building, and microphones in many rooms allowing the occupants to respond to announcements. Sound reinforcement systems and PA systems may use some similar components, but with differing application, although the distinction between the two terms is not clear-cut. Sound reinforcement systems are for live music or performance, whereas PA systems are primarily for reproduction of speech.In Britain any PA system is sometimes colloquially referred to as a tannoy after the company of that name now owned by TC Electronic Group, which supplied a great many of the PA systems used previously in Britain.

Analog CCTV system The main difference between an analog and IP camera is the way in which the video signal is delivered. Analog cameras turn the video signal into a format that can be received by a television or other receiver such as a VCR or monitor. An IP-based camera, also known as an IP network camera, digitizes the video signal using a specialized encoder that contains an onboard web server. This allows the IP camera to act as a network device, thus allowing captured video images to be viewed not only through an existing network but also through a web browser that can be accessed through the Internet. Both analog and IP-based video cameras can transmit signals either wirelessly or through wired connections such as Cat-5 cables. IP-based cameras have the added benefit of being able to use switches, hubs, and routers that allow the Cat-5 network to be expanded to much broader ranges. Benefits of analog security cameras: Lower cost – An analog system is more affordable and usually is more than sufficient for remote monitoring. Greater flexibility of design – Analog cameras often come in a larger variety of designs such as mini covert cameras to large PTZ models. If you have unique surveillance needs you may find it easier to find the style of camera you need in an analog model. Superior compatibility – It is much easier to mix and match cameras and brands if you use analog versions. This can make it easier if you already have existing camera equipment that you wish to incorporate into your surveillance system. Disadvantages of analog security cameras: Lacks certain features – Many of the basic analog cameras often lack some of the more advance features such as digital zoom. Potential interference problems – If you are installing a wireless surveillance system, analog systems can have interference problems. More importantly, the resulting signals cannot be encrypted. This can potentially mean that someone else can view the signal. Long distance applications are more difficult – If your surveillance needs encompass a wide area, analog cameras may not be your best choice. Analog cameras generally do not accommodate big distances, and getting them to work over broad ranges can be difficult

An audio and video intercom system can help secure your property by allowing you to visually confirm, and audibly speak to visitors to your home or business, without risking forced entry by unlocking / opening the front door. One or more door stations can be added to allow multiple entry points to be controlled and monitored by the intercom system. Typically door stations may be used to cover front and / or rear gates, the front door, a granny flat, or any number of potential access points to your property. The intercom system can be used to allow remote access to the entry point by simply pressing a button on one or more installed handsets. An electronic door strike can be installed, allowing a wooden door to be automatically unlocked, a magnetic lock can be used for frame-less glass doors, and gate / garage motors can be used to automatically open sliding gates, and garage doors. For convenience, multiple handsets can be installed throughout your home and business, allowing you to answer one or more of the calling stations from any number of convenient points. Camera modules can either be integrated within the entry point door station for a sleek, neat and clean appearance, or can optionally be mounted externally from the door station, allowing the best angle, zoom, and configuration for the video feed for the intercom system. Some video intercom systems even support remote pan, tilt and zoom of the camera module. Furthermore, the intercom system can even be designed to allow you to make audio only intercom calls from one handset to another, such as calling from the kitchen, to the garage, calling between floors, or even calling a separate dwelling such as a granny flat. Next Links Security System can provide you with an intercom system to suite your needs, and your budget.

Introduction to Door Access Control Systems Access control systems provide authorized individuals safe and secure access in and out of various parts of your business while keeping unauthorized people out. They can range from electronic keypads that secure a single door to large networked systems for multiple buildings. Access Systems also greatly simplify management of your facility: no need to replace lost keys, hunt down old keys from terminated employees, or wonder who has access to which areas. Spend a couple minutes framing the following two questions; (1) What purpose will your door access control service serve? and (2) What size access system will your business need? 1. What purpose will your Door Access Control system serve? To start, sit down and determine the purpose the access control system will serve. The most basic role of an access control system is to keep out anyone who is not supposed to enter an area. This can be the front door, a parking garage, a server room, a personnel records room, or any other sensitive area. You may also want to use an access control system to track when employees come and go. Another point to consider: how secure do you need the system to be? A basic system usually features a keypad or swipe card. Higher security applications may require multiple means of authentication (a card and thumbprint, for example) and include more redundancy. Finally, consider what other systems need to connect to your access control system. Monitored alarm systems and CCTV systems are two good examples. 2. What size access system will your business need? Next, once you understand the general role the access control system will serve, think about the number of doors you need to secure. Smaller installations may include just one: a server room with an electronic keypad lock is a common example of a very small access control system. Remember that not every door has to have access control; you can simply leave some locked and only give keys to appropriate personnel. If you plan ahead a little when purchasing your system, you should find it fairly easy to expand later. The smallest systems, designed for one or two doors, are not very expandable, but many four and eight door systems can be linked together when you need to expand. Once you know the number of doors you will be securing, gather information on each one: the physical makeup and use of your doors will impact the type of locks and entry systems you need. Here are some additional questions to help frame your thinking. • Are some doors for customers, and some only for employees? • Are the doors wood, steel, or aluminum and glass? • Are any designated as fire doors? • Do you have any garage doors or parking lot gates to control? • Larger installations may include more than one site. An access control system that can be operated over a network lets you manage the security at all your locations from a central point. • Another key distinction in access control systems is the difference between free exit and controlled exit systems. In a free exit system, there is no requirement for leaving a secure area. The system either detects someone approaching an exit (usually through motion sensors) and unlocks the door, or has a release button or bar that allows people to Exit. In a controlled exit system, the system requires the use of the same security for travel in both directions: employees have to enter the code or wave their card to get in or out of the secure area. By law, access control systems have to be set up to allow people to exit if the system fails or power goes out. Controlled exit systems increase both security and your overall costs
