The market for home security systems is saturated with devices of varying degrees of effectiveness. As technology develops, some solutions are replaced by others, allowing you to minimize the level of threats. A separate place in the assortment of manufacturers of such equipment has been occupied by video surveillance systems for several years now. Full-format equipment is gradually giving way to miniature devices that are easier to disguise without losing functionality. One of the most attractive solutions of this kind is a wireless video peephole that works offline. Of course, it is not free from shortcomings, but according to some parameters, users indicate that there is no alternative to such proposals.
General information about video eyes
Traditional eyes are a lens that allows you to observe what is happening directly behind the front door. Models provided with video surveillance capability contain a special camera with a matrix in their design. Such devices not only record, but also broadcast the recorded material directly to the monitor of the owner of the apartment. Moreover, it can be a complete small display, and a computer withTV - there are practically no restrictions in organizing the reception scheme when it comes to connecting through common interface standards. What is especially important, the wireless video peephole on the door does not require a direct wire connection to the camera. Information is transmitted by radio signal. Moreover, high-tech modifications are equipped with mobile communication modules, that is, they have no restrictions on signal propagation at all. In real time, the user can watch the broadcast from anywhere in the world.
Functional additions
Despite its modest size, the video peephole can be equipped with a wide range of additional options. In particular, infrared illumination is a mandatory component of premium versions. Added to this is the light sensor, which activates the camera when the light is turned on or off. The main entry-level segment is represented by wireless video eyes with recording, but there are also models with a photography function. Also, some modifications support the possibility of lens movement. This is a new technology that is used today in typical CCTV cameras. The peephole in this case can rotate depending on the sensor readings. This feature increases the efficiency of observation, but such models are much more expensive.
Popular models
The segment includes manufacturers of not only alarm systems, but also digital equipment not related tosecurity function. Nevertheless, experts still recommend that you trust your property to specialized manufacturers who focus on the development of security systems. The entry-level devices are Sititek Simple, Vizit Lux and budget Falcon modifications. These models are characterized by a small signal transmission radius, the absence of additional functions and average mechanical stability. A more advanced wireless video eye with a sensor can be represented using the JMK JK-109 as an example. But this model has one feature. It can be called wireless only conditionally, since the analog camera itself is connected by a wire to the decoder and the router receiving the signal. Another thing is that the further signal propagation radius has no boundaries and at least covers the home network.
Positive reviews about video eyes
The indisputable advantages of such devices, users include providing the ability to monitor what is happening near the front door. With all the technological complexity of organizing this security option, its usefulness and effectiveness are noted. Also, the owners of the most advanced devices of this type emphasize ease of use. Already in the middle segment, a typical wireless video peephole makes it possible to monitor through a smartphone without special monitors.
Negative reviews
There are video eyes and negative aspects that relate to both installation and operational properties. For example, before integration into the door leaf,evaluate the characteristics of a particular model in detail. In some cases, users do not even have to select the design of the eye for the characteristics of the door, but design the carrier sheet itself for a security device. The owners also point to another drawback that the wireless door video peephole has in all versions without exception. Getting rid of wires as such obliges the user to regularly replenish the charge of the battery, from which the camera is powered. However, if the model is provided with a motion sensor, then the energy consumption can be significantly minimized, since the camera will be activated only at the moments of need.
How to make the best choice?
If a decision is made to equip the door with a video eye that works without wires, then several technical and operational aspects will need to be taken into account. First of all, the conformity of the design and dimensional parameters of the model of a particular door is evaluated. Then you can proceed to consider the method of signal transmission and the choice of the system through which the video material will be viewed. For example, an inexpensive wireless video eye with radio modules will allow you to watch the broadcast only at home using a complete monitor, computer or TV. If you plan to monitor the apartment directly from the workplace or from the dacha, then you need to purchase models with GSM modules.
Question of price
Budget models with limited functionality can be bought for 2-3 thousand rubles. This isnot necessarily devices with low quality element base. They can also demonstrate reliability and stability in operation, but at the same time they will not allow to fully exploit the advantages of new technologies. On the contrary, the wireless video eye from the flagship series will provide several modern auxiliary options at once. But it will also cost at least 10 thousand. The most technologically advanced models with motion sensors, GSM modules, infrared illumination and a large memory card are available on the market for an average of 15-17 thousand.
Conclusion
Security experts often warn homeowners against purchasing many of today's devices that promise innovative levels of protection. Such suggestions may well impress an inexperienced user, but in practice they turn out to be hardly useful. Can a wireless video eye be attributed to this group? Rather not, because it does give the homeowner the option to expand their security tools. Another thing is how effective a particular modification will be in specific conditions of use. It is important to understand the purposes for which the broadcast will be carried out - in particular, what algorithm will be used to respond to the fact of a hacking attempt.
