The variety of video cameras on the Russian market can be considered an advantage and a disadvantage at the same time. On the one hand, many models and types of video cameras provide unlimited possibilities for security; on the other hand, the variety complicates the choice. This is especially true when you consider that an ordinary Russian consumer is just beginning to realize the need for hardware video surveillance in everyday life. The domestic video surveillance market is developing at the expense of the public sector and large corporations.
Let’s see what a video camera with a motion sensor is and why you need it.
The main difference between a video camera with a motion sensor and a recording from other types of cameras with recording is in the principle of operation:
In this case, the motion sensor + camera is a structure under a single body, where a separate circuit is reserved for the motion detector.
The sensor is in autonomous operation and “waits” for changes (movements) in its field of vision. In this case, the video camera practically does not consume electricity, since most of the nodes are in a dormant state.
If the detector detects movement, then it gives a signal to the video recording node and sends a notification about an alarm situation.
The resulting image analysis can be performed on the matrix or directly on the server that processes the images.
Hardware detection method
With the hardware method, the motion sensor can be either separate or built into network cameras. Therefore, a moving object identification can be based on the determination of body heat (infrared rays), radio waves, ultrasound and other signs.
If the sensor is a separate device, it becomes possible to purchase a high-quality sensor that will respond as accurately as possible and give a minimum of false alarms.
Principle of operation: when a moving object appears in the field of observation, the rays are interrupted. This is the signal to activate the camera.
Accordingly, such specific equipment is installed in places where there is no intensive flow of people. However, this does not mean that cameras with motion sensors are used only in private households, private plots, or apartments.
Such equipment is in demand for monitoring large objects (industrial zones, car parks), retail outlets, offices, catering facilities and the public sector.

5 Tips for Choosing the Best Sensor Camera
Buying a video camera with a motion sensor is as easy as shelling peas, but choosing a camera that will suit all your goals is quite a challenge.
I want to share some practical tips for choosing a video camera with a motion sensor:
Analyze your goals and financial capabilities. Answer the questions:
Study the websites of manufacturers, sellers, thematic forums, reviews. Check the equipment package.
Read the article “4 options for storing video recordings from surveillance cameras.”
Assess the risks, the degree of responsibility for data storage, the cost of the service.
Refuse to buy a camera on Chinese sites. Read the article “9 reasons why you shouldn’t buy video surveillance on AliExpress”.
Do not consider the noname brands sold in the domestic market— select equipment sold by authorized dealers. Make a comparative analysis based on real customer reviews.
Conclusion: this algorithm is universal, including purchasing a video camera with a motion sensor.
If we talk about using a video surveillance system for home and small business, then cameras equipped with a motion sensor can be the best solution. This equipment consumes little energy, can have extended functionality and fulfils its duties with dignity.
