What kind of video cameras for a video surveillance system. Difference in operating principle. High definition outdoor CCTV cameras

To install cameras in common areas the consent of the Board of Owners will be required and will be reflected in the minutes of the Board. It is recommended that the agreement reflect some characteristics of the CCTV system, such as the number of cameras or the space covered by them.

Whenever images of people are recorded and before they are captured, the file is registered in the General Data Protection Register of the Spanish Data Protection Agency, which will be carried out through the system. They will be installed in various modes of access to the video vigilade area and, in a visible place, one or more posters that announce access to the video surveillance area. The poster clearly states the identity of the person responsible for the installation and who and where the rights under data protection regulations should be exercised.

Likewise, the remaining information required by data protection legislation will be provided to those affected. Information may be available in concierge, reception, offices, notice boards or be accessible via the Internet. The cameras will be able to capture images of common areas of the community. Images of the public road cannot be captured except for the minimum access strip to the property. Images of neighboring lands and residential premises or any other outdoor space cannot be captured.

Contracting an external CCTV service or installing cameras by a third party does not exempt a community from complying with data protection legislation. Access to images will be limited to people designated by the owner community. Under no circumstances will it be accessible to neighbors via a public television channel.

If access is made via an internet connection, it will be limited to a user code and password that will only be known to people authorized to access such images. After installing the system, it is recommended to change the password, avoiding easily subtracted ones.

The recording system will be located in a secure or restricted access area. Recorded images will only be accessible to authorized personnel who must enter a user code and password. Images will be retained for a maximum period of one month from their capture.

Images that are used to condemn crimes or violations are accompanied by a complaint and can be stored for delivery to the Security Forces or Corps or to the courts and tribunals that require them. They may not be used for any other purpose.

The request for images of the Forces and the Security Corps will be carried out as part of judicial or police actions. The request to the file holder will be a document that protects the latter for the transfer of data to them or to the courts and tribunals that require it. To record or view them directly on a monitor, we need to consider a few things. With each of our CCTV security cameras we will need to clarify the following.

To make choosing security cameras easier, we have included a small guide that will be very helpful when choosing your cameras. A guide to choosing your security cameras. It is important for you to clearly understand the use of a security camera in order to choose the one that the best way suits your needs and you can have the perfect CCTV system and feel secure enough to think that your security needs are covered and making the most of your investment with the right camera.

These security cameras are different elegant design, variety of colors. Most of these surveillance cameras include infrared lighting for night vision and can be used indoors or outdoors. Dome cameras can rotate 360 ​​degrees horizontally and 180º to see even objects that are slightly lower. They can scan, tilt and zoom in and out. Like security cameras, options are available for indoor and outdoor use. and most include infrared illumination for night vision.

CCTV Cameras Main feature cameras of this type is their hemispherical shape. These cameras are designed to be installed directly on the roof and allow for discreet installation without much attention. There are dome security cameras that are vandal-resistant, and there are options for indoor and outdoor use.

To determine the amplitude of the area that the camera can image, we will need to choose the correct focal length of the lens. A surveillance camera with a shorter focal length captures more scenes and has a wider field of view. In contrast, a longer lens widens the scene and reduces the field of view. In our product descriptions, optical measurements are given in millimeters. Use these examples to determine what field of view your application requires. Video where you can see the field of view provided by different surveillance camera lenses.

With higher resolution, better definition, clarity and image quality. Cameras with lower resolutions provide images with less detail. Surveillance Camera high resolution can capture a face in detail or a license plate over a large area. The longer the area you want to view, the more resolution you need to see all the details. If you want to monitor a smaller area and don't need a detailed view, a lower resolution camera can take care of that.

Currently there are Various types cameras and very cheap prices, many of which have such inconsistent performance that they end up not serving the purpose for which they were purchased. Cameras are selected according to the required resolution and image resolution.

Best Features for Making a Security Camera Purchasing Decision

The image resolution set by the camera depends on whether it has special features to enhance the image. Type and quality of image capture chip. Keep in mind that the manufacturer of the image capture chip can mean a big difference in video quality.

High Resolution: The native image quality of security cameras, its resolution is measured in: megapixels, frames per second and other special features. Resolution Lines: This is a measure of the image's resolution in analog cameras. In this case best camera will be the smallest. Backlight compensation compensates for the backlight situation by preventing the camera from being brightly reflected when it has high light intensity behind the subject.

Camera Lens Sets the angle and depth of field of view you can get with the camera. Varifocal lens. Allows you to manually adjust the coverage angle and depth of focus. It has the ability to automatically control the amount of light it receives to give the best image.

Example: a person positioned in front of a well-lit window. Both systems perform the functions of measuring, compensating and adjusting image illumination. Infrared Cameras Night vision or infrared cameras have the ability to view in low light or dark environments. To create images, LED lighting technology is used, which allows you to see even in a multi-color range, depending on the technical characteristics of the camera.

Typically, infrared cameras operate like a regular color camera during the day, and when the ambient light decreases to a certain level of darkness, it automatically turns on LED lamp backlight. The number of LEDs in an infrared camera determines the distance in meters to where the camera can be observed in dark conditions.

When you choose a camera brand for your CCTV system, you are making a decision about the amount of risk you are willing to accept. Within a few weeks the vast majority installed cameras had water penetration. It was necessary to calculate the costs associated with the work of the integrator to replace the cameras and add the costs associated with equipment downtime. The fragility of a CCTV system can be physical, as in in this case, or software, such as vulnerabilities that could allow unauthorized access.

And the perception of risk usually only occurs when the purchase decision has already been made, the project has already been established, and the problem has already escalated. The manufacturer no longer has enough paper specifications that it says its system provides. Now the so-called "concept test" has become increasingly common: the client installs cameras in a real-life situation for a time to maintain the performance of the equipment itself before choosing a brand. This allows you to check whether what the manufacturer says is true and reduces the risk of disappointment after the investment.

In reality, every decision involves risks. The choice of a particular brand determines the amount of risk a customer is willing to accept, taking into account the reputation of competing brands, warranties, availability and flexibility of technical support, the history of other customers, investments in system security products made by private groups and government agencies, and a number of other indicators .

There is also the risk of finding entire batches with serious failures. In some cases, the problem makes the images unusable to view. While any manufacturer is theoretically susceptible to these failures, it is important to adopt a strict quality control process to reduce the likelihood of entire batches being wasted. When the camera reaches the customer's hand and comes out of the box, it should work perfectly.
