Wireless mini cameras for hidden video surveillance are installed in apartments and offices. The compact size allows you to record from any convenient point in the room.
Varieties of mini cameras for hidden video surveillance
Mini camcorders differ in design, method of execution and principle of operation. Wired models require the use of cable products (such as twisted pairs or fiber optic products). For hidden installation, they are rarely used due to the difficulty of organizing an inconspicuous conductor run. Mostly wireless cameras are purchased for these tasks.
Analog
In small analog models, the transmission of the picture is realized by means of an electrical TV signal. They are susceptible to interference, which can even be caused by the weather. Now such devices are not popular due to the proliferation of miniature digital models that provide good picture quality at an affordable price.
Digital
A wireless mini-camera for video surveillance is installed in the range of mobile signals. Usually these are models for use in a home or organization: street installation is rarely practiced. Wall obstructions slow down signal transmission. Reducing the transmission speed can create network interference, while they practically do not affect the quality of shooting.
With internal memory
Some devices have a slot for a removable storage, others work only from the internal memory. Copying the recording obtained as a result of tracking to a computer or laptop in this case is carried out using a USB cable.
Mini wifi cameras
A remote access hidden home security camera transmits a signal to a PC via a router. The recording can be stored on a computer or in a cloud service. The user can view what is happening in his home from any device with Internet access. The model can be powered by mains or battery. Some wireless mini covert surveillance cameras are equipped with a motion sensor. Recording initiation when this indicator is activated allows the device to use memory more economically. You can configure the sending of a mobile message to the user when a sensor is triggered, which will help to respond to threats more quickly.
Mini web cameras
For home installation, such cameras work via the Internet and WiFi. The user can connect to it from their device anywhere. When traveling, the device acts as a video recorder.
Spy mini camcorders
Such devices for covert video surveillance can be disguised as certain objects or devices, or installed inside them. The video camera can be in the form of a car keychain, pens, brooches, or hide in a breast badge. For home use, the device is placed, for example, inside a security sensor.
Main characteristics of mini cameras
Cameras are used for the following purposes:
- control of the security of a home or office in the absence of people;
- tracking the activities of staff - for example, a housekeeper or nanny;
- control over the work of the organization's employees;
- performing the function of a video recorder for a car;
- recording of seminars and lectures.
For power supply, rechargeable cells and other types of batteries are used. There is an option to connect to the mains. Special miniature batteries are produced for micro cameras.
Despite its size, many modern devices are capable of recording video in HD and even Full HD quality. The resulting image can be monochrome or color.
Advantages and disadvantages of mini cameras
The main advantages of mini video cameras are portability and compactness. The design allows you to install the device at any point from which an advantageous view of the room or object is provided, as well as to transfer it from place to place. However, you need to take into account - the closer the router is, the faster the signal is caught. Since the field of view of the micro-video camera is unknown to others, their behavior appears in a natural form on the recording. If an unpleasant incident occurs, the filmed material can be used as confirmation (this also applies to the use as a car recorder).
Wireless connection makes it possible to monitor the situation at a protected facility remotely at any time. High-sensitivity matrices available in some devices allow you to achieve high-definition images, as well as shoot in the dark. Cameras are easy to install and configure.
The downside is the small capacity of the batteries: on their own resources, they are able to continuously shoot for only a few hours. However, in observation mode, the devices can operate for up to two weeks. To save battery power (as well as memory), the function starts recording only when the motion sensor is triggered.
Criterias of choice
The viewing angle of the device is selected in accordance with the purposes of its purchase. A large angle is required to cover a large area. However, in this state of affairs, a high definition of the image is not always achieved. If image detail is a high priority, a model with a low angle is needed. When installed near a window or above a door, such a camera can be directed towards the gate.
Resolution matters: the larger the number, the clearer and better the video will be. For wider coverage, zoom lenses and other accessories are used. There are miniature cameras that can provide quality shooting that allows you to identify a human face at a distance of 50 m.
The sensitivity of the devices, measured in lux, determines the minimum level of illumination perceived by the sensor. Camcorders are often equipped with LED backlights to allow nighttime shooting.
The presence of a microphone will be helpful. A legible recording of audio signals is obtained within a few meters of the device.
Models that work with Wi-Fi signals are preferably mounted inside the room. This is because there is a high likelihood of lower transmission rates when passing through walls and similar obstacles. This effect is especially pronounced in concrete buildings with metal reinforcement. Also, signal distortion can be introduced by household appliances operating with microwave waves. The distance to the receiver recorded in the technical documentation shows the limit of direct visibility. GSM camcorders are equally suitable for indoor and outdoor installations.
How and where to install
When performing installation work, you must adhere to the instructions given in the accompanying documents. It is important to consider where the camera will be located. For covert shooting, it can be placed in a suspended ceiling structure or wall niche.The viewing angle of the device itself and the optimal area of the controlled space are also taken into account.
You will need to buy a video recorder for the camera. When choosing, you need to pay attention to device compatibility. It is optimal if they come from the same manufacturer. The purchase takes into account the format of video recording, the number of channels for sound and image, and the speed of the process. You will need to adjust the parameters with which the device will work: contrast, brightness and sensitivity.
To set up the equipment, you will need a monitor and a special cable with connectors for connection. Having placed all the equipment in the provided places, connect the wires to the devices for video recording. Then connect the connecting cable and the power supply unit (while observing the polarity). The monitor is connected to the recorder and connected to the power grid. Now you can start recording.
A number of legal prohibitions
The law prohibits the installation of hidden cameras in public places. When installing such equipment, a warning sign must be placed in the controlled area. Otherwise, the camera can be confiscated and the owner fined. If such a device is installed in an office or other institution, this must be reported to all employees. It is advisable to conclude an agreement on the collection of information and familiarize employees with it against signature.
Filming in a dwelling is allowed if the video is not going to be distributed in the future. At the same time, it is forbidden to disguise the equipment as household items (such as lamps and clocks) or place it in them. Even for the purchase or sale of a tracking device designed as an everyday item, the law provides for imprisonment for up to 4 years. It is not prohibited to place a camera in a security or fire detector, but it is recommended to hang a sign nearby.
The law does not allow the operation of models with a very high sensitivity (in figures - 0.001 lux or less) and with the shape of the lens in the form of a needle eye. Such devices are classified as spy devices.
It is necessary to warn everyone who visits it about the presence of a camera in a home. If a nanny or other service staff works in the house, they also need to be notified.

Yeah, and tell me where it is installed and how to disable it))
