Using the monitoring of such parks and playgrounds, squares, fair account should be taken that the camera is working in variable conditions (rain, frost) on the outside so you can use the external Surveillance Camera housing with heaters and thermostats.

Fundamental issue is to choose for each specific application of the respective lenses. Incorrect selection of the lens may cause malfunction of the system.

• Auto-iris lenses are typically used outdoors, where the prevailing changing lighting conditions.

• Manual iris lenses are used normally for internal applications where the light level remains constant. That we decide on the type of aperture, we need to stand before choosing a focal length lens.

Lens focal length is related directly to the angle of view, to be achieved. Small focal lengths give a wide viewing angle. Large focal lengths give a narrow viewing angle. Thus, in order to allow the specific identification of vehicles and people from long distances should be mounted lenses with long focal lengths.

We recommend monitoring of school-based color cameras. Color system allows for better observation of detail, and therefore better meets the requirements such as the observation of the crowd in the corridors or in the locker room. However, these cameras are less sensitive than black and white and require additional lighting, but this should not be a problem, because this type of facility must be provided with artificial lighting. If you happen that do not have such lighting, you can use the infrared headlights that will replace the lighting and will be able to work with security camera systems at night.

Such reflectors can be used to illuminate the poorly lighted places of visible light. However, in our offer we have the camera with its own color and infrared cameras colors day / night, which they see well in both day and night and do not need additional lighting. Such devices can be used to observe fields, playgrounds and parking lots.

As for mounting the same cameras that are exposed to various acts of vandalism by the students, then they should be installed as high as possible. Some cameras are placed in enclosures made of polycarbonate, which are impact resistant up to 500 kg, so it is not possible to change the camera angle by the saboteur. Others are mounted in housings on stable holders to withstand even a light strike the ball.

• Diagram attached by us to the emergency kit is a sample conceptual. Are described in the electrical connection elements. Do not suggest the color scheme or method of connection.

• Since each element of the system (detectors, sirens, keyboards) keep separate wires to the control panel. Thus, each element should have its own cable run to the headquarters. There is no need to conduct additional cable from the detector to the detector, or from the siren to the siren!

Example of wiring diagram.

• Make the electrical connections inside the enclosure control panel.

• Before connecting the power, confirm that all connections.

• In the configuration EOL / NC (Standard) terminals tamper with the individual devices should be connected together in series them or using screw connections. Tips resulting tamper circuit is connected to the appropriate terminals headquarters.

• With the expansion of an additional PIR housing should be starting their “NC” connected in series, and the ends of the resulting circuit to the appropriate terminals of the control panel.

• Terminals “M” at its headquarters DT3K are equivalent – that is, both connected to the central mass.

• COM terminals in the headquarters SATEL are synonymous.

• PIR sensors when you first start doing the test (by repeatedly attaching transmitters on and off, blinking LED).

Megapixel camera make it possible to achieve a resolution several times higher eg a 1.3 megapixel camera get 1024 x 768 px on the camera 2Mpx get maximum 1600 x 1200 px.

Complete IP monitoring can be built using a cheaper camera series AVI201 and AVI202. For image recording, you can use a Windows PC with installed software Video Viewer. There are, however, IP cameras for standard definition and analog cameras. However, have a built-in video server, which converts the signal to an IP broadcast. Analog image quality does not differ substantially from the picture of the IP camera.

A better solution if we are able to monitor the use of IP megapixel cameras such as the IPC-F725P included with the camera is included with software for managing and recording video with a maximum of 36 such cameras. The camera is equipped with an FTP client so you can configure it so that it will be sent the video stream and (or) images to an FTP server. Using this configuration will be guaranteed to play recordings in the event of failure of the recording unit.

CCTV systems – monitoring of schools should be designed so that taking into account the size of buildings and facilities, as well as their character. We must also note the financial resources available which educational facilities available to them. Therefore, our offer has been divided into three sets in terms of pricing, and hardware.

Should monitor all the main entry as well as a less important on the school premises. In these places you need to install these cameras, which will have an opportunity to identify persons entering the facilities. Security Cameras should be mounted close to the corresponding inputs or lenses, which will only see the front door. The recording material so the camera will set the detailed analysis and information about the appearance of unwanted guests.

Other very important places that they should be registered are changing rooms and long corridors school. In such places the camera must be located as high as possible to their field of vision was the greatest. In the locker room or in corridors, such cameras are often vulnerable to attack from the students, so we advise mount cameras. In such places also recommend to install more security camera systems to each other was in his field of vision, as well as after it, to increase the safety of students at the site of the school.

We must remember the security area around the school. Playing fields, playgrounds and parks and other places are very dangerous places. It is worth remembering the same school, which may be vulnerable to acts of hooligans especially at night.

Youth staying in school is exposed to various types of crime, theft of clothing and other personal belongings, extortion and beatings, as well as crimes associated with narcotics distribution. Therefore, the use of a monitoring system to prevent the entry of outsiders into the premises, theft and acts of vandalism and displays of aggression among students.

The main purpose of this monitoring network is primarily the protection and safety of students, teachers and the school, which can still be destroyed by vandals. Application of this Security Wireless Camera system makes the school save money on repairs, thus the costs incurred for setting up the system soon to return.

We have a very long list of schools which have benefited from our offer. In these schools, the emergence of such a system could be seen a large improvement in safety and disappearing acts. Blessed are the directors have made a contract to continue to develop registration systems.

There is a possibility of connecting schools to the CCTV system for monitoring urban base.

Protect yourself, your family, your employees, your valuables, and everything that matters to you with this great security / surveillance

Monitoring of the city is not easy to implement because of the large number of cameras deployed in the city located at large distances from each other, in this case, is cumbersome use of conventional CCTV systems based on wired cameras.

To avoid the troublesome installation of CCTV wire, we can use IP cameras and video servers, which made possible communication between the center of our surveillance and cameras via the Internet. Just that, properly configured our IP camera and connect it to the Internet. Built-in web server allows us to quickly and easily configure the camera and reading an image by internet. After configuring all the cameras we can keep monitoring the city.

Another interesting and highly functional solution being applicable to the monitoring of the city are receiving or transmitting wireless sets of 5.2 GHz and 5.8 GHz CAM, allowing radio broadcasts from the camera images to a recorder. Set consisting of a transmitter and receiver very well in a dense urban area. If you choose to use kit CAM CDS5021h operating at 5.2 GHz frequency, you can connect to the recorder at a distance even 2km, the device also has a system of transmission encoding is resistant to disruption of large grids and Internet broadcasts provides full resolution image PAL at 25 frames per second. An alternative is to use traditional wired cameras and connecting them to the video server, which then are connected to the Internet. Video servers can handle multiple digital video recorders and transmit signals simultaneously from all cameras.

Monitoring of the city becomes much simpler using video servers equipped with embedded web servers, FTP clients and PPPoE allowing communication with camera and video server for the global network and viewing the camera from a web browser. Check our CCTV Blog and CCTV Forum.

When buying a camera requires an industrial state in what conditions the camera will work. Very important is whether the registration of the image “seen” by the camera will take place during the day or at night may be in both situations, so you should choose an appropriate camera and lens.

When choosing a security cameras stand in front of the camera choice whether to apply a color or black and white.

Due to the observation of the illustrative much better results are obtained using a system based on color cameras. Color system allows for better observation of detail, and therefore better meets the requirements such as the observation of the crowd on the street, customers in supermarkets. However, it is less sensitive than black and white cameras. Despite all the advantages are more colorful cameras.

Installers often ponder the question, whether or not to propose a better system of cameras in black and white. Spectral sensitivity of the camera in black and white covers the range of infrared, so using infrared lamps can be discreet observation at night. It is worth mentioning that for the purposes of CCTV Infrared is light that is invisible to the human eye but is visible to the monochrome camera. Wavelength infrared radiation is in the range from 700 to 1000 nm (nanometers). However, the drawback of black and white camera is the observation of the crowd, where you will not see the details.

Important parameter is the size of IP security cameras. The camera has an impact on the viewing angle. The use of a lens with a larger format than the format of the camera sensor to decrease the angle of view.
This combination gives in turn increased the resolution and image quality, because it is used only to measure the lens where the optical elements are polished with greater precision.

There are the typical standard-definition cameras – monochrome and color 420/480 line – 350 to 580 lines, which are well fulfill its role in the observational systems.

570/600 and 460, respectively line allows you to read later registered better performing camera, equipped with good quality lens and the cover of the heaters equipped with a thermostat will certainly not fail the expectations and ensure the generation of good images in all conditions.
Due to the nature of the observed object, children and adolescents should take into account the camera, which may be vulnerable to accidental or intentional damage.

In order to limit direct access to the camera to be used in the assembly of the upper parts of the premises, apply additional housing that will prevent such change in position of the lens focus ring. Stable fixtures – which are not sensitive even to hit such a ball.

Gives much better results use the handles of metal twisted “traditional bolt” rather than cheap plastic handles with ball-joint.

In the case of ceiling dome cameras we use with polycarbonate vandal enclosures. Top Security Camer Systems.

Using the monitoring of such parks and playgrounds, squares, fair account should be taken that the camera is working in variable conditions (rain, frost) on the outside so you can use the external camera housing with heaters and thermostats.
