Walls, furniture, doors are likely to hinder the transmission. These are somewhat cheap products and each of the cameras has multiple receiver techniques. But the quality of image is relatively poor and the signals aren’t quite secured.

2.  Digital Wireless Cameras- The digital security cameras are by far the best ones. The signal is secured, the image and sound quality is fantastic, the cameras are multiple receivers enabled, a wide ranged transmission is provided, the receiver and camera share a two-way communication and furthermore, the digital signal catches even the slightest movement or blink. All these unparalleled benefits have prompted a relatively costly price but once you start using the system, you’ll certainly feel contented. Signal transmission in digital IP security cameras is done via digital packets.

In these emergency wireless setups the receiver and the camera communicates with the help of a frequency which is common to both the units. There are generally four available frequencies for the wireless camera. When a certain frequency is broadcasted, all the four camera units share it. The CCTVs usually have an in-built video receiver and transmitter separated from each other. When the camera is installed, it uses a specific frequency so as to transmit signals to receiver which is connected to the security monitor.
