Features IP-Surveillance systems

Every day CCTV systems are becoming more popular. Ceased to be purely a niche product designed for use in commercial facilities, video surveillance systems are put in city apartments and country houses. And this is not surprising, because with the help of video can be seen in the preservation of property, to conduct remote site monitoring and control of workers in the process of construction of the house.

In this regard, many questions arise concerning the possibilities of such systems and the peculiarities of working with them. Therefore, in this article we will, with the help of specialist companies MACROSCOP, describe the following:

• What are the features of a system for IP-CCTV cameras.
• As specialized software reduces the cost of installation of IP-Surveillance system.

Judging by the popularity FORUMHOUSE topics related to video surveillance, the last 2-3 years among our portal significantly increased interest of users for such equipment. For example, a user with the nickname

moiseevsd I would like to organize the monitoring of the apartment, with the possibility of getting an image on a mobile phone or laptop from anywhere. He was echoed and Denver82.

Denver82 (Member FORUMHOUSE):

I build a house, but do not have the opportunity to constantly go to the site, as work. I think to put video to the Internet, online, monitor all activities of workers at a construction site. I would like to learn how to do it?

Construction experience shows that remote video access with the ability to record actions of the brigade can improve the quality of work and time to prevent fatal mistakes job. Moreover, having decided to install a video surveillance system, it should be planned in advance, first determine what it is you need.

Just control the workers, their browsing activities online, and then dismantle the camera and equipment? Or mount a more advanced video surveillance system, for example, with the help of special software software (allowing to find a particular person on given attributes) to identify the worker, for allowing marriage? Alternatively, collecting basic embodiment, further upgrade it by extending the functionality. For example, to install additional chamber with motion sensors. Or install a high-definition camera running software that recognizes numbers entering or exiting the area of ​​motor vehicles.

Such a carefully thought out and rational approach to create a surveillance system for growth.

For example, the video system to network cameras (eg with IP-cameras), with its own dedicated IP-address and support the transfer of data over a local network. This allows broadcast and view high-quality image (video image) on your mobile or stationary device having access to the Internet at any distance from the installation site equipment.

ShmelevAndrey (User FORUMHOUSE):

I had already decided that I would do a video surveillance system in theIP-chambers through POE, with a motion sensor capable of recording data both on the DVR, and the "cloud" storage. I want to figure out how much it will cost me a system of 6 exterior cameras, and 2 street?

Vitaly Teplyashin (CTO Macroscop):

PoE technology (Power over Ethernet), used in the IP-camera allows to transmit power through the Ethernet cable (twisted pair), which simplifies the installation and surveillance system costs. Because power supply, the video stream and the device is controlled by a single wire, and hence there is no need for additional wiring.

Choosing equipment for video surveillance systems, it is important to strike a balance "price-quality-functionality" because unjustified saving leads to a reduction in the quality of the entire system.

One of the points of dispute in the construction of a video surveillance system is the choice of cameras - analog or IP-cameras. Above, we have already identified a particular IP-cameras. Consider now the analog camera.

The principal difference between this equipment - data transmission method, which directly affects the functionality of a video surveillance system.

The analog signal from the camera matrix is ​​digitized, and then converted to analog for transmission analog cable device (e.g., DVR or video capture card in the special PC). In this case, the incoming signal at the input to the receiver is converted from analog to digital again.

IP-camera digitizes and processes Incoming analog image, then encodes it, and transmits in digital form on the target device on the Internet and LAN connection.

By connecting the IP-camera (resolution of 2-3 and more Mn) to the local network can immediately view high quality video picture from any mobile or stationary device, giving control commands and save information.

Mounted systems once, it is possible without more material and labor costs, at any time to install additional IP-cameras, using the already paved cabling infrastructure.

In addition, these cameras, in fact, is a device with built-in computer running its own operating system. IP-cameras have a RAM (random access memory), WEB server, your own IP-address, a slot for inserting a memory card (eg, microSD).

Vitaly Teplyashin:

camera withThe SD-card in the event of a disruption in the network connection and the gap in the sequence of "camera server" allows, with a corresponding installed software, restore your data. Those. when resuming communication server pulls the missing data from the SD-card and synchronizes them with the main video archive. The result is a continuous recording.

On this basis, it becomes clear: to unlock the full functionality of IP-Surveillance requires specialized software.

Features and capabilities of specialized software for IP-Surveillance systems

Practice shows that most users are not limited to 1-2 with surveillance cameras, and prefer to gradually increase their number. Even if the homeowner initially assumes that will cost a minimum of cameras, it does not mean that in 2-3 years, he does not want to put a few more pieces.

Conclusion: even in the initial stage it is necessary to pay special attention to the selection of a video surveillance system components, with the expectation of the future.

Vitaly Teplyashin:

The development in the segment of technologiesIP-Surveillance equipment leads to lower prices. Those. you can collect a functional system without sacrificing its quality.

For example, one IP-camera 2-3 can replace analog, as transmits the image in high resolution.

In addition, the camera can be connected by pulling only one cable.

Accordingly, reduced installation costs, laying of cable lines, channels, etc.

Another way to reduce costs - the choice of the specialized software. After processing video streams from multiple cameras requires large computational resources, and special software allows you to reduce the load on the processor and system.

Vitaly Teplyashin:

For example, using specialized software, which produces compressed video analysis video streamingIP-camera without its complete decoding can increase the processing speed by 4 times. This means that the server processes more data and do not need to purchase additional or more powerful equipment, which leads to a significant reduction in the cost of building the system surveillance.

 You can also reduce the load on the server, using the potential of the software and the function of video analysis software. This method is based on the fact that modern software can:

• operate on the motion of extraneous portion;
• track crossing extraneous virtual line;
• detect a person and to respond to the appearance or disappearance of an object;
• capture a scene change monitoring, etc.

Using video analytics function, you can set up the equipment in a way that will not be treated all the videos, but only right to us in accordance with a predetermined scenario. For example, people using congestion detector can be evaluated and their quantity in excess of the set parameters to notify the user. Filtration video server is unloaded, and therefore reduced requirements for its power.

Vitaly Teplyashin:

You can also combine analysisIP-camera with an analysis on the server, for example, to carry out face detection camcorders forces to transfer these movies to a server, where they will be analyzed by the face recognition module.

In addition, to reduce the load on the server processor can, using special software is used to process parts of the GPU operations (GPU) graphics cards.

Thus, the use of professional software optimizes and reduces costs for design IP-Surveillance systemsAnd to test its capabilities can be by downloading demo product.
