WIFI cameras for a good price. WIFI cameras are IP cameras that have the ability to operate through WIFI connection, which allows you to avoid laying new cables. WiFi cameras can operate autonomously, you can connect directly to the camera by phone or computer from anywhere in the world. WiFi cameras are able to record video and / or audio to a microSD card or cloud server, in which case a recording device that is typically used when installing 2 or more cameras is not required. WIFI cameras for continuous professional surveillance require only electricity and sufficient WiFi connection strength. Some WiFi camera models may work with rechargeable batteries, but these cameras monitor the environment only when motion or user login is activated, they are not designed for continuous monitoring, and require periodic recharging of the batteries. WiFi connection is still less stable and reliable than wired connection, but more and more professional systems are being deployed over WiFi only after a correct assessment of connection strength. The maximum operating distance declared by wireless manufacturers is specified - 50-300m. However, the actual strength depends mostly on the obstacles between the camera and the WiFi station. Each wall, ceiling or floor between them reduces the signal strength by 25% or more depending on the thickness. Thus, the connection strength beyond 3-4 walls may be too weak for the camera to operate stably. Also in outdoor conditions the connection is affected by many factors like wind, rain, snow. In all conditions, before installing WiFi cameras, especially outdoors, it is necessary to test whether the connection in this place is really sufficient and stable enough. If it's not enough, try changing the planned location of the camera or the existing WiFi station.
