While trying to figure out which model, style or type of hidden or surveillance camera you need, you must also decide on a wired or wireless version. Do you know the difference? Do you know the benefits and disadvantages of each?
A wireless security camera transmits video wirelessly to a receiver. The receiver is then connected with RCA Cable directly to your recording device (such as a DVR, VCR, or a computer). The receiver will sit right next to the recording device. Short RCA cable will connect the receiver to the recorder. A disadvantage of a wireless camera is that you may experience some interference. You may see lines or a fuzzy picture occasionally on the playback video. This happens because of other wireless devices in use while your camera is on. Those devices may disrupt the transmission of video between the camera and receiver. The benefit of a wireless security camera is that you do not need to worry about hiding long cables. The receiver is also small enough to tuck behind your recorder, which isn’t that necessary since it can look like a piece of other entertainment equipment along with your recording device. You can place the camera wherever you like as the transmitter can penetrate through walls (note that it cannot penetrate very well, if at all, through brick, cement, metal, and sometimes glass).
A wired security camera requires RCA cables to run from the camera directly to a recording device. You will need to determine the length of cable you will need that will accommodate the distance between the camera and recording device. A disadvantage would be hiding the cable. You may need to run it through walls, or under carpets. Otherwise the cable will be visible to others which would not work well if you want to be discreet and are in need of a hidden camera. You may consider hiring an electrician to help run the cables from your camera to recorder, as well. The benefit of a wired camera is that you will always have a clear picture with no interference because the video is going right through the cable to your DVR, VCR or computer. They are also less expensive than a wireless version.
