SECURITY CAMERAS
In Surveillance aware of the concern for their safety people working for years in the installation of security cameras and systems CCTV. Since what we seek in a maximum security facility is not work with products from a single source provider but we think it has right products to the type of installation you are performing and trying to carry solutions with affordability.
Despite what you may think, installing closed-circuit television or CCTV involves a pre-installation of the devices work. This previous work depends the smooth functioning of the system and its durability over time.
The CCD type, focal length, aperture, chrominance, minimal lighting, impedance, sealing need infrared and many other items are to be considered and calculated before choosing the right product. Problems like Blooming or a miscalculation of the depth of field can make a costly installation work as a mediocre facility because the images are blurred and do not identify an individual who is conducting an antisocial act.
Similarly, in places where the installation of security cameras is done by radio encrypts the signal is important because, otherwise, we may be providing information to our system of closed circuit television (CCTV) to a third party with the right equipment. This obviously poses a security risk.
So in Surveillance:

    "We do not sell equipment, sell security"

CCTV SYSTEM. FEATURES AND OPERATION OF SECURITY CAMERAS
The use of cameras CCTV is commonplace today. Ministries, town halls, sports arenas, shopping centers, warehouses, factories and many other places have this kind of equipment. Also, a particular level also increased the use of these devices, mainly in homes and vehicles mainly due to insecurity that occurs in certain areas or simply to have added protection.
In Surveillance we cover the needs of companies and individuals designing and installing the necessary equipment as required covering. It's not about spending money on a system based on security cameras (CCTV), but of investing team. Therefore we need a system that meets current needs and future needs if at a magnification of it is necessary. It is often possible to install an affordable cctv.
A Closed Circuit Television basically consists of some imaging equipment (camcorders) and a television screen or monitor. Additionally, in case you want to record the images captured by the television cameras a video recorder is used. If we have to record the signal from many cameras need a digital video recorder with more capacity (250 GB, 500 GB, 1 TB) and a device called a multiplexer that allows us to record many signs and then view images captured by each camera separately on a single monitor. Many video recorders lead the integrated multiplexer and allow us to install many security cameras up number.
The connection between security cameras and the rest of the system CCTV can be made via cable or even satellite radio.
Security camera image
Cable installation through:
The system connects the dots that separate cameras, video recorders and monitors via the wires that were placed connectors to make connections with devices (usually type connector is BNC type). A cable runs through the television signal to the VCR and monitor.
The cable offers advantages such as stability of the signal, image quality, definition and other advantages, but has the disadvantage that it can be cut in some points and thus the signal stops flowing to the recording equipment or viewed. To remedy exists the tamper wire that surrounds the cable in a steel mesh and is more difficult to cut.
Cable another problem is that much more expensive system when computers are far apart, since it is presupposed by meters. Sometimes you have to overcome obstacles that raise the system to take more amount of cable or a special type of cover. (Egg to pass the cable through the roof gardens must be anti-humidity). The cable that is typically used is called as coaxial, however according to the conditions can be used other.
Installing Satellite Radio:
In this case the points between camera and recorder attached via radio waves carrying the video signal. Therefore it needs a transmitter that is placed next to the cameras and transmits the radio signal to a receiver that picks up the signal again to turn image, which is distributed between the VCR and monitor.
Depending on the distance can reduce costs, but it also has drawbacks: the signal is low and sometimes images can be worse, wind, storms or other devices may interfere the signal obstacles between camera and video recorder may lower the broadcast signal.
Also, if someone has a similar reception equipment could get to see the signal emitted by our CCTV cameras. It is not recommended either that there are many cameras that broadcast radio signals do not interfere because each camera is on a channel.
Radio cameras
Interior Installation

Indoor facilities are often conducted via cable to prevent the partitions, walls and furniture impede the arrival of the signal, however if there are chances that the equipment is sabotaged in the environment the cable can be adjusted and put wire tamper in sections in which protrudes from the wall.
Indoors one of the problems there is often the light, the cameras need some light to clearly show what is in your field of vision so it is advisable to assess the fact that at the possibility that the light is Minimum cameras with an infrared system or a spotlight that illuminates autonomously.
Another advantage is that having walls, ceilings and walls is easy to place cameras hooked to these places supports. Yet we must bear in mind that the cameras should be positioned very accessible way for people who might be inside.
Outdoor installation
These systems CCTV have the advantage that on the light conditions are usually best for their operation, however, at night we should see if the electricity is not enough and if blurs the camera lenses. If there are no bright or it may be cut off it is desirable that the cameras with Infrared system to see in the dark.
If the cable is protected against external inclement we may have problems with the weather. We can also choose the option of installing radio if possible.
Another problem that we provide the weather is that cameras CCTV are sensitive to sudden changes in temperature and humidity, so in some places use special housings that will protect from the cold and / or heat to the cameras, many are also tamper and carry a shield to prevent fogging, freezing or frosting glass can be heated and the drops of rain or dew not impair vision can carry cleaning brushes. There are many more options depending on the customer requirements and demands neutral conditions.
black and white
Black and white or color,
Many of our customers make us this question since both systems have their advantages. The black and white image is sharper and well balanced tones from black to white through grayscale. Allows the outlines of the figures look very good. But does not give details of the color images. In return they are brighter, that is, less light is needed to make them look good. Therefore in places with low light are recommended, especially associated with infrared light.
Color cameras are today the most widely installed, because most come with infrared light and when there is little light switched to black and white and feature images with less outside brightness.
The main advantage of color is given for when what is needed is security is essential to describe individuals or vehicles that are on the monitor. It is not the same as a vehicle to make it look gray red, or a person seen dark brown coat and blue trousers to see it gray and black.

For these reasons today are typically used infrared color cameras.

Proper installation of CCTV Surveillance System

Proper installation of CCTV Surveillance System

After determining the area or areas that you want to put under surveillance, the next step is to make sure you have successfully installed the system. Note that improper installation does not work, so even if you buy the latest equipment will not work if it is not installed correctly. If you have experience with the installation of electronic equipment, it is a good idea to hire a professional security company to perform this part of the job.

Where to put the camera lens

One of the most important determinants in terms of how well they work security cameras where the lens is placed. It must be ensured that the areas to be monitored are being targeted and are clearly visible, it is essential to take into account the distance from the camera to the point of interest. Also, if you want to mount the camera on a wall or structure, make sure it is securely installed so that the camera does not shake and motion distort the image.

Recording CCTV surveillance cameras

Another thing to keep in mind when installing security camera systems is whether CCTV surveillance video recording. If you are buying a CCTV recording system that allows you decide, be sure to select one that is compatible with security cameras. Options include the old recording videotapes VCR or digital video recording on a DVR.
To better identify the most appropriate solution in your system of CCTV security cameras may be helpful to consult with a professional security company. They will help to determine which safety components are best for your purposes and what are the right places for installation are.



How does a safety system works by CCTV?

How does a safety system works by CCTV?

Keep your home safe and secure at all times can be a difficult task, especially when you have to go out and leave the house empty. Fortunately, systems security cameras help maintain a high level of safety regardless of whether or not present in the house. With security cameras CCTV closed circuit can keep an eye watching your home 24 hours a day and at the same time deter thieves just let them know they are being watched and recorded. 

Video surveillance is also useful in case of being robbed, because it can be a great advantage for the police in the task of identifying and capturing the guilty person. To determine the best security system CCTV to install in your home, you need to know a little about the surveillance cameras work.
Security systems CCTV

Visible and hidden cameras


Before deciding where to put CCTV security cameras, something to consider is whether you want to be visible or hidden. Both types of cameras have their applications and appropriate places for installation Visible cameras are best when placed in areas where thieves can see they are being watched, as being outside the house or in the living room. Hidden cameras are designed to record the actions of thieves without them knowing you are watching and are excellent to hide them in places like the inside of an alarm clock or within an intercom system.

How does CCTV works?

How does CCTV works?
A CCTV system is comprised of video cameras that capture and send images to one or more monitors (or TV) or a video recording device through what is called a CIRCUIT.

The CCTV CIRCUIT

There are two types of circuits for CCTV. The analog and IP-based networks.

Analog CCTV

An analog circuit generally requires a dedicated wiring to carry video signals generated by the cameras to a central computer and from this central signal is derived monitors and video recording devices. It requires a cable for each camera installed.

IP networks based CCTV

A circuit of this type is based on IP technology (in which the same is based Internet). In this case, the cameras have within a minicomputer with the ability to convert and encode the video into data that can be sent over a computer network, whether a network already installed in the business or home, or the same network Internet.

The advantages of this system is that it is cheaper still to facilities already existing network can be used: the same wiring used (or you can use wireless networks), and can be used one or more PCs to view and record video images. It is clear that this will depend primarily on the number of cameras and benefits are needed.

Another advantage of IP-based CCTV networks is that thanks to the minicomputer that have cameras, you can set the system to react before certain events or circumstances, for example: recording only when motion is detected, send alerts by email, SMS or phone, record the situation, triggered at certain times, etc.

Hybrid CCTV

In this case the analog and IP based systems coexist. Usually this type of CCTV is used in the event that there is a prior installation of CCTV analog type and wants to expand the system or the new system based on IP networks without discarding the old system used. In this case any additional equipment such as converters and / or adapters are used to convert analog signals to digital.

Video surveillance cameras

There are a variety of cameras that can be incorporated into a CCTV system. The choice of camera depends on the needs and objectives of each case, and the environment where they will be installed. For that reason we always do a preliminary analysis of the environment that you want to monitor to design a reliable and efficient solution.

According to circuit technology, cameras can be:

Cameras Analog: for analog circuits.
IP cameras, for circuits based on IP networks. Quickly they attach to any type of computer network.
The cameras are broadly classified as:

Indoor Camera: for environments protected from weather.
Cameras outside: these cameras are ready to operate in areas exposed to moisture, extreme temperatures, etc.
Dome camera: these cameras have a call dome housing that make hiding more discrete design and direction you are pointing. They can be installed both indoors and outdoors, there are even more vandal resistant housing with tamper-resistance and vandalism.
Plus:

Fixed cameras, these cameras have a fixed field of view once installed. It is one of the most used types and is the ideal choice in applications where it is useful that the camera is visible.
Mobile cameras PTZ (Pan-Tilt-Zoom): These cameras have the ability to change their orientation with vertical / horizontal movement, zoom and also according to the operator's instructions. The movement is controlled through a much like a joystick that sends control signals to the camera device.
There are other options for special cases such as:

Cameras for night vision camera estipo can generate infrared images from
Thermal cameras: these cameras produce images based on the heat that radiates from any object, vehicle, animal or person. These cameras can be installed in full darkness and deliver a video image for an operator to suspicious activities at any time.
Video recording devices

The images generated by the cameras, whether they are digital or analog, can be recorded to keep a log file or review the video at another time if you want to verify or prove something.

In an analog system, it is necessary to have special equipment to do this work. In the case of a CCTV based on IP networks (or hybrid) , this equipment can be replaced by a computer running a software program that takes pictures of the cameras and generates video files, saving significant costs and usually You can use any available PC in the business or home.
