We have a variety of wireless camera receivers. Some can plug directly into your TV while others can connect directly to your personal computer such as our usb wireless camera receiver. We also have wireless Digital Video Recorders (DVR) that use flash memory to store video files just like your digital camera! Another neat concept is our mobile LCD receiver’s you can carry around with you. Some of these modles also record the images right to a SD card! Our Wireless IP Cameras use your PC and the Internet to store your pictures and video files. Most of our wireless camera receivers are 2.4 GHz unless other wise stated and many of our wireless receivers are 4 channel as well. Simply put, you can run up to 4 wireless security cameras on the one wireless receiver.
