When it comes to buying wireless pan tilt zoom cameras, the experience is a little different than purchasing wired one.
Actually, firstly, wireless is rally a good solution especially you want to keep your house clean when you install the security cameras, just plug and play, wireless signal transmit distance Max. 40m which I think it is enough for a house indoor or outdoor.
Secondly, you can save a lot for the install labor cost cause it is wire free, without punching on the wall. It is easy for DIY.
However, as it is wifi, the biggest challenge is the transmission distance. the distance between the wifi ptz camera and the router range from 15-40m. especially, if there is a wall interval, the signal is weak, which make the image or video unstable.
