Camcorder with motion sensor and night vision

Modern security systems with the use of GSM technology usually involve the inclusion of video cameras in the system. But it's not just cameras with the ability to fix "pictures", but devices that in real time are able to react to what is happening in the surveillance zone. To this end, manufacturers use modern sensors that allow the signal to be sent to the central control panel. However, the simplest systems are designed only for notification of the owner through the means of mobile communication. The main thing in such a system is the type of sensor. The most effective option is a video camera with a motion sensor and a night vision, which allows you to monitor the surveillance zone regardless of the time of day and, if necessary, give appropriate signals to the user.

Features of the camera with a motion sensor

The main difference between these models is the ability to record on the motion detector. This means that in normal state the camera is idle, and its activation begins only when the action begins to occur in the observed field. The benefit of such devices is to save space for recording. In order not to use capacious servers for video material, the developers suggested optimizing the recording process itself, initially eliminating the equipment from processing unnecessary data. At the same time, a modern digital video camera with such a sensor can have memory cards with 32 GB or more. The storage capacity can be determined not only by the device activity time, but also by the recording quality.

Analog and Digital Models

It is generally believed that the fashion for motion sensors arose during the period of popularity of digital equipment. But this is not entirely true, since analog cameras were previously equipped with similar detectors. Another thing is that such equipment has problems in compatibility with registrars, when it is necessary to send a signal. For today the digital video camera equipped with motion sensors is more popular. It is these models that have the ability to inform the owner about the presence of movement in the protected area. The lack of such a function in analog cameras is also their serious drawback. There are other differences, but they all boil down to the fact that digital devices are more technological and functional.

Thus, the latest models of IP cameras provide the owner with ample opportunities for communication via the Internet. As a result, even sending SMS-messages at the moment of fixing the action is becoming less relevant. For example, a modern video camera with motion sensor can use e-mail and other channels to notify the owner, which increases the reliability of the security system.

Main characteristics

Of great importance in the efficiency and quality of the operation of such cameras is the resolution and the number of megapixels. The standard devices use a 5-megapixel matrix, which provides recording in 1280x720 format. Next, you should pay attention to the possibility of recording sound. This feature is not available in many models, but the presence of a microphone with a quality recording significantly expands the capabilities of the equipment. It has already been noted that a video camera with a motion sensor can be equipped with memory cards. Their volume on the average varies from 32 to 64 GB - this is enough if it is planned to operate equipment with short periods of activity. Also an indicator of high efficiency of the camera is the possibility of pre-recording. With this function, the device saves the video material not from the moment when the activity is fixed in the field of view, but buffers a few seconds before the traffic starts. This interval varies on average from 3 to 10 seconds.

Possibility of night vision

The use of infrared illumination and thermal imagers allows for the possibility of night vision. This addition is organically combined with motion sensors, which allows to expand the functionality of the equipment. By the way, depending on the technological implementation of such models can be effective in different conditions. For example, a light-sensitive video camera with a motion sensor can fix objects in the dark only if at least a minimum illumination. In turn, thermal imaging analogs are independent of light and are able to work, focusing on thermal radiation. As technology develops, hybrid models also appear, but they are not so widespread because of the high cost.

Mini video camera with motion sensor

Such devices are the best option if you want to implement a hidden observation. In size, they rarely exceed the size of a matchbox, which provides great opportunities for the unseen eye of the installation. Also mini-devices do not lose full-size analogues in performance characteristics. For example, the latest models allow recording in FullHD format and are equipped with infrared LED-illumination for night vision. However, in terms of autonomy, a mini-video camera with a motion sensor demonstrates less high performance. The average recording time of the battery model is 1-2 hours.

Models for outdoor use

To such models, the most stringent requirements are met in terms of mechanical protection of the hull. The material must withstand physical impacts, precipitation, wind and still maintain performance. In some cases, it is advisable to pay attention to the means of additional protection - it can be, for example, anti-corrosion coating or anti-vandal case. You should also take into account the management method. In most cases, a street camera with a motion sensor includes a remote control kit. This allows you to monitor the operating parameters of the device at a distance, although the memory cards have to be changed manually.

How much is?

The simplest models are estimated at 3-4 thousand rubles. It can be street devices with a basic option and a set of mandatory tools for communicating with other equipment. More advanced mini-cameras are estimated at 6-7 thousand rubles. But this applies to advanced devices that provide both night vision and high quality recording. At the same time, a hidden video camera with a motion sensor that notifies the owner through digital communication technologies can cost 10 thousand rubles. This is the most advanced version of IP cameras.

Conclusion

The presence of various sensors in tracking systems has long become mandatory in security systems. They not only provide a benefit in the form of space savings on servers, but also optimize the monitoring process itself. In particular, a video camera with a motion sensor allows the owner to immediately pay attention to the moments where the action takes place. At the same time, this type of model is organically combined with other surveillance system functionality, including night vision and wireless technologies, as well as the ability to transmit messages over multiple channels. However, there are drawbacks in cameras equipped with motion sensors. So, if the system is programmed to send an alarm signal at the moment the detector is triggered, then any random action will be superfluous and unnecessarily troubling the owner. The usual situation is when a room camera with such a sensor is triggered by the movement of a cat or dog.
