In the modern world, people are increasingly using increased security measures, since technological progress makes it possible to purchase a variety of products for self-defense and home protection. The wireless door peephole has recently appeared on the security device market, but has already gained well-deserved popularity.

It was with his participation that it became possible to improve the safety of your home.

Design features

The good thing about the wireless door peephole is that it is convenient to use and has an affordable cost. Thanks to these qualities, people more and more often acquire this particular device.

It is a combination of two parts: one of them contains a video camera with a microphone with a built-in radio module, and the other contains a video screen with permanent memory. Outwardly, the device looks like a completely ordinary peephole, as it has the same size and shape. It is sold complete with special fasteners that are designed to fix the device in place of the door peephole.

It is because of its design features that a hidden video camera is almost impossible to notice.

It can function both from the mains and from the battery, however, most devices come with a DC adapter.

The diminutive size of the camera does not interfere with full-fledged video and sound recording in high quality. As a rule, the dimensions of the captured video are 640 * 480 pixels. The video recording resolution allows you to clearly see the face of the visitor who is near the door.

Door viewers with video recording are made in two types.

  • A device that is designed to be fixed on the door structure directly on the peephole.
  • A wireless device that is located at some distance from the doorway.

Both types have their pros and cons.

For example, a viewing device may have built-in memory, or it may be equipped with a special module that accepts various memory cards. Most of the models are capable of not only filming, but also photographing what is happening behind the front door.

The wireless video peephole almost always comes in a set with a built-in battery, so it does not need to be connected to the mains at all. Modern models are available in a portable configuration, which includes a radio module that allows video surveillance remotely.

This property greatly simplifies the life of many people, especially those with physical disabilities.

Pros and cons of survey devices

Installing a wireless video peephole in the apartment is necessary for additional security.

This device has a number of advantages that prevail over other surveillance systems.

  • The main advantage of a wireless system is its stealthiness. It is almost impossible to detect video communication from the outside, it is noticeable only with a thorough study of the door.
  • Another advantage of the device is its budget. Its cost will not hit your pocket, but it brings a lot of benefits.
  • Due to the miniature size of the product, it is easy to install. Its installation does not take much time, and after installation it is very easy to work with it.
  • It is also convenient that it is not at all necessary to be near the door in order to personally control what is happening on the staircase. Hidden audio and video recording allows you to monitor in real time without leaving a cozy place.
  • The video eye device is equipped with only a few buttons, which is very convenient. To use the device, you do not need special knowledge and skills, so a person of any age can cope with it.
  • It is important that under the current legislation, citizens have the right to provide digital recordings as evidence, so when trying to hack, the video will help find and catch intruders.

The huge number of positive qualities of survey devices did not exclude the occurrence of some shortcomings in them.

  • The radio module is highly susceptible to operational interference.
  • The compact camera has a low resistance to mechanical damage.
  • Cordless devices are not able to hold a charge for a long time, especially at low temperatures. The temperature range of stable operation of the device is limited. The same goes for some models. The cheapest options can only function in a specific temperature range. As soon as the device goes beyond the permitted limits, it immediately fails, and this can lead to damage to the electronics or the battery.
  • Data transmission takes place using a radio channel, and the occurrence of interference will make it impossible to receive data. Interference on the line can arise for many reasons: the presence of specific devices nearby, parts with a conductor, and so on. There are devices that are specifically used for radio wave plugs.
  • The miniature wireless camera has low durability. A few awkward movements are enough to damage the device, but some manufacturers produce shockproof models that are almost impossible to break.

Additional options

Wireless video surveillance systems can have various additional functions.

Some models are equipped with an infrared motion sensor and a GSM module for data transmission. The infrared motion sensor will automatically turn on the camera when movement occurs at a certain distance from the door, while the device either starts filming or taking photos - it all depends on the settings.

The GSM-module is necessary in order to be able to receive the recorded information to any device connected to the Internet. This allows you to observe what is happening near the front door, even when you are far from home.

Videos and photos can be saved in order to study them in more detail in the future.

How to choose?

Choosing a surveillance device for private video surveillance, you need to decide on its functionality.

For example, an infrared motion sensor is an absolutely meaningless function in an entrance with automatic lighting. When choosing, it is necessary to measure the size of the door peephole in order to purchase a device of exactly the same parameters, otherwise there will be difficulties during installation.

You also need to consider the viewing angle. Often it makes no sense to purchase a camera with a long range, usually a 90 degree rotation is sufficient. If the owners want to be able to communicate with guests online, then it is worth purchasing a device with Wi-Fi support.

A useful function is a motion sensor, with which you can find out about the visit of visitors even before they ring the bell.

The purchase of a device for private use should be adapted to the average static requirements. Professional video cameras have a number of enhanced characteristics that are not clear to the average user, and they cost many times more than their simplified counterparts.

Be sure to carefully read the performance and customer reviews before purchasing a wireless video eyelet. Remember, the lower the price, the worse the device.

Popular models

When deciding to buy a wireless video eyelet, you need to familiarize yourself with the most popular models in order to identify their disadvantages and advantages.

  • GSM II-2 - a device that is designed to be installed in a peephole. The set includes a memory card, MMC device, charger, battery and fixing parts. Thanks to a miniature screen and a motion sensor, apartment owners can always see the approach of visitors in advance. The infrared sensor is capable of detecting movement at a distance of one and a half meters. The touchscreen display and 100-degree viewing angle add to the popularity of the device.
  • Radio DVR - a device equipped with a 5-inch large screen. It is not necessary to install it in an apartment at a short distance from the video eye, but you can take it with you. It has a built-in automatic shutdown and shutdown function, which significantly saves battery power. The product is made of brass, and therefore has a low weight. The video surveillance kit consists of a video peephole, antenna and stereo headphones.
  • Home Voice - an inexpensive model of the survey device, which is equipped with a minimum set of functions. With its help, you can conduct a two-way dialogue and observe what is happening behind the door through a small monitor. In fact, it is a mini-intercom with video communication.
  • Sititek i3 - a device based on "android" and has a Wi-Fi module. Also in the external module of the device there is a bell, backlight and motion sensor, and inside the product there is a built-in touch display, on which the image is clearly visible.
