Modern security systems for various objects are based on video surveillance. Cameras equipped with a cable are not very convenient to use. Difficulties can arise already at the stage of installation work, and besides, such devices are very expensive to maintain.

The optimal solution is the installation of a wireless mini camera, which has several advantages. Devices of compact size are easily and inconspicuously fixed in any necessary place, have high signal quality, and a simple system of settings.

A mini wireless camera is a video surveillance device that transmits information over a mobile network or via Wi-Fi. The device may be equipped with additional storage for storing footage or a special slot for inserting a memory card. Mini cameras are used in security systems to ensure security and track all events occurring at the facility.

Criteria for Choosing a Hidden Mini Camera

When choosing this type of camera, it is important to consider the future purpose and purpose of the operation. Attention should be paid to different criteria: device sensitivity, resolution, continuous operation time, viewing angle, information transmission method, etc.

Resolution and Sensitivity

The higher the resolution setting, the better the video quality will be. The sensitivity parameter, which determines the maximum lighting performance, is measured in Lx (lux). For indoor shooting, you can choose a device with a sensitivity of up to 1000 Lx. For poorly lit outdoor areas, as well as for shooting in cloudy weather, you will need a device with an indicator of at least 3000-4000 Lx.

Viewing Angle

Mini cameras with a narrow viewing angle will capture a limited part of the territory, but the quality of the shooting will be excellent. To observe a large area, it is better to purchase a camera with a wide viewing angle. The picture may be slightly distorted. Try to choose a device with high performance in other specifications to get better pictures.

Memory Card

Mini cameras can be equipped with a MicroSD slot. Memory cards are required to record material. If during the shooting the device loses connection with the device where the information is transferred, the footage will be automatically saved to MicroSD.

Important parameters of a good memory card for wireless cameras:

• Capacity – standard volume 32-64GB;
• Operating temperature range – for continuous operation in different environmental conditions;
• The number of write/erase cycles – determines the duration of the card.

Consider these essential factors to choose the best wireless mini camera for your use.
