IP (internet protocol) Cameras

IP cameras are cameras that send their video signals over a network which can be wireless or via a network cable,they encode from the camera itself, as IP cameras are essentially tiny computers and they can record at a high resolutions that is captured in megapixels of between 1-8megapixels which is 6 times the resolution or clarity of any image, they can also have smart features or specific parameters which you can set automatically for security purposes which  includes motion detection, people counting, face detection, line crossing, remote view applications and several other smart features. IP systems for CCTV can be a high initial cost, but saves money on the long-term by using fewer cameras, less cabling, less maintenance.

Network Video Recorders (NVR)

 Network video recorder (NVR) are devices that save  video images to a hard drive, they come with 4, 8, 16, 32, 64 camera inputs and  they contain compartments called SATA in which hard drives HDD are installed for storage, they playback video recordings of events that are stored in the HDD, they can be connected in 3way to cameras namely wireless,  via a CAT 6 or CAT 5e network cable and in areas where several cameras are required within a large a  switch, this switch can then run back to the NVR, saving substantially on cabling, installation, and maintenance costs

HD (High Definition cameras)

HD cameras are cost friendly alternatives to IP cameras they capable of capturing high definition video surveillance footage up to 1080p resolution (1920 x 1080 pixels).   These cameras can transmit uncompressed high-definition video over coaxial cables,  there are 3 types namely HD-CVI, HD-TVI, HD-AHD.

HD-CVI (Composite Video Interface) promoted by dahua allows for high-definition analog images including video, audio, and serial data to travel well over five hundred meters with just one line of cable without video loss.

 HD-TVI (Transport Video Interface)promoted by Hikvision allows for high-definition analog images including video, audio, and serial data to travel well over five hundred meters with just one line of cable without video loss

 AHD (Analog High Definition) promoted by samsung allows for high-definition analog images including video, audio, and serial data to travel well over five hundred meters with just one line of cable without video loss

 None of the technical specs really differentiate from each other. There are minute differences in what chips or image sensors they’re using, but ultimately serve the same function with manufacturer reputation playing a big role in choice

While IP cameras can encode from the camera itself HD cameras send their data to Digital video recorders DVRs for encoding.

DIGITAL VIDEO RECORDERS

A digital video recorder (DVR) is a device usually connected with HD cameras for recording they convert and compress analog video signals to digital format and store into a hard disk drive or any other storage device.  They come with 4, 8, 16, 32, camera inputs, and support features such as remote access motion detection, real-time playback, they are easy to set up and use.

Indoor cameras (Dome)

Indoor Dome Cameras are designed and specified for indoor surveillance use only, in most cases they are not designed to withstand the rigors of outdoor weather conditions, so they must be used indoors in most cases.

Outdoor cameras (bullet)

Outdoor bullet Cameras are designed and specified for outdoor surveillance, however will work very well as indoor cameras as well, they are weatherproof and can withstand the rigors of outdoor weather conditions, so they should be used outdoors in most cases.

IR infrared

 Infrared LED is lighting positioned around the outside of the camera lens in order to capture information in areas where there is absolutely no light. No matter what the environmental conditions are, infrared measures the heat coming from objects in the area, and this can be read by the camera with no light required. Infrared can also travel through fog, dust and smoke no matter how thick. It can even travel through some materials. They work regardless of the lighting conditions, giving you a sharp set of eyes even in absolutely zero light.  You can compare quality of CCTV cameras according to how far they can see in complete darkness. This is measured according to how many infrared LED’s are built in to the camera, IR in cameras come in different ranges from 30meters IR to 500Meters IR and above

Depending on how much property you want to protect, you can select your cameras by short range IR vision or long range cameras that have higher range of IR.

MP (megapixel) What Does Megapixel Mean In Security Cameras?

MP megapixel is associated with IP cameras only, A pixel is a “picture element residing on the image sensor (in a camera).”  The quantity of pixels helps determine the resolution of an image.  All megapixel cameras have a minimum of 1,000,000 pixels which means the image is comprised horizontally and vertically 1,000 x 1,000 pixels, the advantage in megapixel cameras is the ability to use less cameras to cover larger areas , Megapixel recordings are clearer in resolution than standard cameras therefore storing footage for longer periods of time. The MP of a camera range from 2MP – 8MP.

RG 59 coaxial cables for HD CAMERA installation

RG59 Siamese CCTV cable allows installers to run both the video and power HD cameras using a single cable run. RG59 coaxial cable comes in 305 M 500M and 1000M spools. The RG59 cables have a solid copper core and 100% copper braided shielding. This is the best type of coax cable to use for CCTV and HD CCTV installations.

RG59 is cut by professional installers to the exact length that you need for each camera run. The RG59 portion of the cable is COAX and is used to run the video to the security camera. The 18 gauge pair is used to run the AC or DC power to your cameras.

CAT 6e NETWORK CABLES

 Cat 6, is a standardized twisted pair cable for network installation use , they are used for the installation of IP cameras and they come in spools of 100metre, 305 metres,5oo metres ,it  is cut by professional installers to the exact length that you need for each camera run.

HARD DISK DRIVE (HDD)

A hard disk drive (HDD), hard disk, hard drive is a data or video storage device that uses magnetic storage to store and retrieve digital information using one or more rigid rapidly rotating disks (platters) coated with magnetic material. It comes in different sizes ranging from 500 gb- 1terabytes – to 6 terabytes, the more the bytes, the more storage of video storage monetary value also depends on the size of the byte

A fire alarm system has a number of devices working together to detect and warn people through visual and audio appliances when smokefirecarbon monoxide or other emergencies are present. The most common systems are categorized into two namely the conventional system and the addressable system, this system consists of the panels and devices attached to them that completes the system.

Conventional system

Conventional alarm panel

A conventional fire alarm panel facilitates location and control of fire within a building by subdividing the system into definite areas or zones, Zones are usually made by dividing a building, or area into different sections. Then depending on the specific zone, a certain amount and type of device is added to the zone to perform its given job. i,e Floors of a multi-storey building are one type of zone boundary. the kitchen area can be another zone, the car park area can be another the panels come in 2 zone panels,4 zone panels, and  8 zone panels depending on the size of the structure , they are usually used on smaller projects such as  schools, stores, restaurants, and apartments etc, the  panel must be connected to  three devices namely   conventional smoke or heat  detectors, manual call point or siren bell.

A complete Conventional alarm panel system would comprise of the panel which can be

2 zone panels (allows you to divide your area of installation into 2 zones),

4 zone panels (allows you to divide your area of installation into 4 zones)

8 zone panels (allows you to divide your area of installation into 8 zones)

Conventional smoke detectors

Smoke detectors  are   devices  that senses smoke, typically as an indicator of fire in a home or a Commercial property, they are used in mostly for small buildings, such as individual offices or retail or commercial properties or sizeable residential homes that are big in nature, In a conventional system, smoke detectors are typically wired together to monitor each zone and a single fire alarm control panel usually monitors a number of zones which can be arranged to correspond to different areas of a building. In the event of a fire, the control panel is able to identify which zone or zones contain the detector or detectors in alarm.  Conventional fire alarm systems are much less expensive than the addressable system,

Heat Detectors

A heat detector is a device that senses a dramatic elevation of heat in a home or Commercial property.  Heat detectors are not meant to replace smoke detectors  but are usually installed in utility areas where smoke detectors should not be installed as dust or other particles would affect the smoke detector and cause false alarms.

Conventional manual call points:

makes it easy for people to raise alarm of fire danger in their immediate area, by manually pressing down firmly on a plastic element on the device or breaking the glass on the device which sends a signal to the alarm panel and sets of the siren or bell to alarm people in that vicinity, they are installed at regular intervals throughout a building both indoor or outdoor.

Conventional fire bell / siren

Notifies people of a fire by making pitched ringing sounds to alarm people and get quickly to safety. It is installed at regular intervals in a building both indoor and outdoor.

Conventional sounder/flasher:

A visual signal  known as beacon, flashalarm or strobe is a luminous source within a coloured transparent enclosure as additional alarm warning to the fire bell alarm  in the event of fire, to ensure that people who did not hear the bells, can see the lights flashing to warn of danger, they can also be installed both indoor and outdoor

Addressable fire alarm systems

Addressable alarm panel

Addressable panels are usually more advanced and expensive than their conventional counterparts, with greater information capacity and control flexibility; they employ one or more Signalling Line Circuits – usually referred to as loops or SLC loops – ranging between one and thirty. Depending on the protocol used, a Signalling Line Circuit can monitor and control several hundred devices with each device having its own address or code,  so the panel knows the state and recognizes each individual device connected to it, common devices used with the panel

Addressable Smoke detectors 

They  are a necessity for large building complexes and industrial properties and other places such as ships and trains or in sizeable residential homes , In an addressable system  each detector is given an individual number, or address allowing the exact location of an alarm to be located instead of a zone and allowing several detectors to be connected to the same zone,   they are are usually more expensive than conventional non-addressable systems, benefit of addressable fire alarms are is that they show exactly which devices are going off, it makes it extremely easy to figure out either where there is a fire or, in the event of a false alarm, which specific device is having a problem. They also require less cabling than conventional fire alarms.

Heat Detectors

A heat detector is a device that senses a dramatic elevation of heat in a home or Commercial property.  Heat detectors are not meant to replace smoke detectors  but are usually installed in utility areas where smoke detectors should not be installed as dust or other particles would affect the smoke detector and cause false alarms.

Addressable manual call points:

makes it easy for people to raise alarm of fire danger in their immediate area, by manually pressing down firmly on a plastic element on the device or breaking the glass on the device which sends a signal to the alarm panel and sets of the siren or bell to alarm people in that vicinity, they are installed at regular intervals throughout a building both indoor or outdoor.

Addressable fire bell / siren:

Notifies people of a fire by making pitched ringing sounds to alarm people and get quickly to safety. It is installed at regular intervals in a building both indoor and outdoor.

Addressable sounder/flasher:

A visual signal  known as beacon, flash-alarm or strobe is a luminous source within a coloured transparent enclosure as additional alarm warning to the fire bell alarm  in the event of fire, to ensure that people who did not hear the bells, can see the lights flashing to warn of danger, they can also be installed both indoor and outdoor.

Standalone smoke detector 

They are typically used in domestic/residential environments as individual standalone units, or interconnected. They typically generate a loud acoustic warning signal as their only action. These detectors are normally used in the rooms of a dwelling and are generally not expensive, they are powered by mains electricity or disposable or rechargeable battery. They may be interconnected by wires, or wirelessly. It is very important to change batteries in this device periodically

Fire Alarm Cable

2 Core Fire Resistant Cable

Fireproof cable cores are designed to provide the highest level of data protection, ideal for long cable runs and addressable fire systems, conventional systems, fire alarm smoke detection and sounder circuits etc

Access control system” most often refers to a computer-based, electronic card access control system. The electronic card access control system uses a special “access card”, rather than a brass key, to permit access into the secured area, they are used to control entry into exterior doors of building or certain areas located within the interior of buildings. The purpose of an access control system is to provide quick, convenient access to those persons who are authorized, while at the same time, restricting access to unauthorized people.

Basic Components of an Access Control System Access are:

Access Cards  

 An electronic key which is used by persons to gain access through the doors secured by the access control system. Each access card is uniquely encoded. Most access cards are approximately the same size as a standard credit card, and can easily be carried in a wallet or purse.

Card Readers

Are the devices used to electronically “read” the access card. they may be of the “insertion” type (which require insertion of the card into the reader), or may be of the “proximity” type (which only require that the card be held in a 3″ to 6″ proximity of the reader. Card readers are usually mounted on the exterior (non-secured) side of the door that they control.

Access Control Keypads

Are devices which may be used in addition to or in place of card readers. The access control keypad has numeric keys which look similar to the keys on a touch-tone telephone. It requires that a person desiring to gain access enter a correct numeric code. When access control keypads are used in addition to card readers, both a valid card and the correct code must presented before entry is allowed

Electric Lock Hardware (Mag Lock)

Electric lock hardware is the equipment that is used to electrically lock and unlock each door that is controlled by the access control system.

There are a wide variety of different types of electric lock hardware. These types include electric locks, electric strikes, electromagnetic locks, electric exit devices, and many others. The specific type and arrangement of hardware to be used on each door is determined based on the construction conditions at the door. In almost all cases, the electric lock hardware is designed to control entrance into a building or secured space.

Access control field panels

 (Also known as “Intelligent Controllers”) are installed in each building where access control is to be provided. Card readers, electric lock hardware, and other access control devices are all connected to the access control field panels. Mostly  necessary for project sized installations and not necessary for small to medium sized businesses.

The access control field panels are used to process access control activity at the building level. The number of access control field panels to be provided in each building depends on the number of doors to be controlled. Access control field panels are usually installed in telephone, electrical, or communications closets.

Access Control Server Computer

The access control server computer is the “brain” of the access control system. The access control server computer serves as   the central  database and file manager for the access control system; and is responsible for recording system activity, and distributing information to and from the access control field panels. Mostly necessary for project sized installations and not necessary for small to medium sized businesses.

A single access control server computer can be used to control a large number of card-reader controlled doors. The access control server computer is usually a standard computer which runs special access control system application software. In most all cases, the computer is dedicated for full-time use with the access control system.

TIME AND ATTENDANCE

Time and attendance systems are used to track and monitor when employees start and stop work. A time and attendance system enables an employer to monitor their employees working hours and late arrivals, early departures, time taken on breaks and absenteeism. It also helps to control labor costs by reducing over-payments, which are often caused by paying employees for time that are not working, and eliminates transcription error, interpretation error and intentional error. TNA systems can also be used to ensure compliance with labor regulations regarding proof of attendance; they come as standalone devices or part component or feature of an access control device.

Security Electric Fences are electric fences constructed using specialised equipment for perimeter security, they consist of wires that carry pulses of electric current to provide a non-lethal shock to deter potential intruders. Tampering with the fence also results in an alarm that is logged by the security electric fence energiser, and can also trigger a siren, strobe, or notifications to a control room or directly to the owner via email or phone.

 Security electric fences are a physical barrier and psychological deterrent to potential intruders, and as part of a security alarm system.

electric fences are used by both private and government-sector bodies to prevent trespass. These include freight carriers, auto auctions, equipment rental companies, auto dealers, housing communities, commercial factories or warehouses, prisons, military bases, and government buildings etc

  • Electric Fence Brackets

They are used to carry both a live (hot) wire and an earth wire to where it is needed. By utilising the strength and rigidity of an existing fence it will thus reduce the costs of the electric fence system. They are generally available in galvanised high tensile steel and can be used with the porcelain and or plastic insulator. They come in 6Line,8Line ,10line and 24Line brackets

  • Wires and Cables

Bright, Shinning Aluminium Alloy Wire 1.6mm (solid ) • Best for high corrosion areas and offers a long life span on the fence. • It has a very low electrical resistance allowing long fences to be powered up from only one energizer •

  • Energizer Panels

An electric fence energiser is an electric device used to control the electrical pulse sent down the fence via a power source, usually battery or mains 240v power. The energiser uses capacitors to store the charge and releases it down the fence line or  live wire and when a person touches the fence an electrical stream flows through the body of the

person and back through the ground to the earth return terminal of the energiser. Generally a pulse is sent down the live wire of the fence about every 1.5 seconds, this can vary across different brands and models of energisers.

  • Tensioners and Insulators

An electrical insulator is a material whose internal electric charges do not flow freely; very little electric current will flow through it under the influence of an electric field.
