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:

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.

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.

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.
