Checkpoints when introducing IP surveillance cameras

Security monitoring such as crime prevention measures in retail stores, safety management in factories, volcanic eruptions and river flooding.At present, surveillance cameras are being introduced for a wide range of purposes and purposes.In this series, we will explain the points to be considered to introduce and utilize surveillance cameras three times.The first one will introduce the current status and precautions when introducing network cameras (IP cameras), which are becoming mainstream of surveillance cameras in recent years.

Surveillance camera market that continues to grow

According to the announcement of Fuji Keizai, a research company, the surveillance camera market in 2020 was 49.1 billion yen, 21 compared to 2016..8%increase is expected (*1).The Tokyo Olympics will be held in 2020, and surveillance cameras will continue to increase as an effective tool for terrorism and crime measures.In addition, for applications other than crime measures, further market expansion is expected to expand the market by providing image analysis and providing services using AI tools.

The "network camera" that connects to the monitor via a network is the driving force of such a market expansion.

In the past, surveillance cameras were the mainstream of analog cameras that connect the camera and the monitor with a coaxial cable.However, the high functionality and expandability of network cameras have been gradually valued, and demand has recently been reversed.According to the Fuji Keizai report introduced earlier, more than 60 % of market share in 2015 is a network camera, which is expected to exceed 80 % in 2018.

Difference between network cameras and analog cameras

Analog cameras and network cameras are roughly divided into two.One is remote control and the other is expandability.

With an analog camera, the range that can be monitored is limited to the distance of the coaxial cable.Of course, if you prepare a long cable, you can earn a certain amount of distance, but in that case, the cost will increase the cost of collapse.In addition, an analog camera is not suitable for a very large surveillance system, as adding a camera is required to add a number of cables and connectors.

On the other hand, a network camera can be installed anywhere in a place where the network is connected, and can be accessed from anywhere and managed and operated by remotely.As long as you can connect to the network, the theoretically, you can add a camera as many as you want, so you can handle it from small to large monitoring systems.For example, a monitoring system that covers the entire factory, and a system that allows multiple stores nationwide to be centrally monitored on the headquarters monitor can be easily realized.

What is the secret to choosing the best network camera?

In recent years, network cameras have been highly functional and high -quality, and there are a wide variety of types.In order to select the best camera from among them, the purpose must be as clear as possible.

For example, in the case of a retail store, the camera to choose differs depending on whether you want to prevent shoplifting in the store or from the outside invasion at night.In the former case, a camera with a wide angle of view is suitable to reduce the blind spot.On the other hand, in the latter case, it is necessary to have a high sensitivity that can be reflected even with a small amount of light than a wide angle of view because it is only necessary to watch the intrusion.In some places, infrared function may be required.

If it is installed outdoors, if it is along the main road with a high traffic volume, it is desirable to have a light amount adjustment function because headlides may not be visible.High waterproofness will be essential for surveillance such as tsunamis and floods, and heat resistance should be emphasized in places like a steelworks.

Naturally, expensive surveillance cameras are highly functional, and there are highly versatile products that combine multiple functions.But unless you have a very rich budget, it is difficult to make all the cameras a high -performance and expensive product.On the other hand, it is also important to pay attention to the cost of the cost with a cheap camera.If it's indoors, inexpensive plastic products may be enough, but you should choose a solid waterproof, heat -resistant metal camera on a strict environment.

I think the network camera is the same as the introduction of the system

Introducing surveillance cameras tends to be aware of the performance and price of the camera itself.However, the network camera is a computer -like manner, which is a computer, which is a computer, in which the image is handled by himself.In other words, the introduction of a network camera always has the introduction of a system via the network.It is necessary to keep this in mind.

Insecam is a hacking site for surveillance cameras that became a big topic in 2016.Here, the video of the tens of thousands of surveillance cameras worldwide has been released, and about 7,000 surveillance cameras in Japan have been confirmed.It is said that many of the hacked causes were because their ID and password remained in the initial settings.

When introducing a system through a network, security measures must be given to the highest priority.The fact that it was neglected is very serious.If a surveillance camera, which should be the purpose of crime prevention, is used for crimes such as information leakage and privacy infringement, it will be overturned.

If you monitor multiple cameras in real time, you will need to devise ways to secure a network band, and if you value the analysis of the recorded video data, consider the storage capacity and reliability to save.I have to do it.System maintenance and maintenance are one of the important examinations.It must be a measure against disorders such as system redundancy and a system recovery system in the unlikely event.

With this in this way, you can understand that the introduction of surveillance cameras is equal to the introduction of a new system.In other words, the introduction of surveillance cameras occurs not only in the camera but also in the system.

In the second time, let's explain what kind of system to choose when introducing a network camera.
