What Kind Of Wireless Surveillance Cameras There Are Available?


Before buying wireless surveillance camera, it is essential to know the main types of wireless surveillance cameras on the market. We at SpyGearExperts.com listed those below.

Reasons for selecting wireless surveillance cameras

There are several reasons why people should choose wireless surveillance cameras over wired ones. The installation of wireless surveillance cameras gives an individual the discretion to select a suitable location, and if needed also secret operation without installation problems. The reason for this is that wireless surveillance cameras are designed to transmit signals even via walls to receiving units like vcr, tv, smartphone or dvr computer.

Receiving units can be described as the places where footage from the camera is either viewed live or stored for future viewing using internal memory. A number of wireless surveillance cameras are equipped with internal DVRs which record to internal memory or an SD card. Despite the fact that wireless surveillance cameras lack complexity, it is crucial to keep in mind that a power source for both the camera as well as the receiver is required. A few wireless surveillance cameras are manufactured with a battery of their own.On the other hand, most wireless surveillance cameras require to be plugged to an AC outlet in order to power the camera.


Wireless surveillance cameras currently in the market are available in different types such as with Wi-Fi and IP-Receivers, Wireless Surveillance Cameras with USB Receivers, Wireless Surveillance Cameras with RCA Receivers, Analogue wireless surveillance cameras and Digital wireless surveillance cameras. The different types are described below:

Analogue wireless surveillance cameras

This type of camera usually transmits signals via waves and cameras are needed to facilitate the transmission of the analog signal through the transmitter. Direct recording to a video recorder is possible with this type of camera. Furthermore, their signals can conveniently be converted to digital for image storage on a PC. To achieve the conversion, the camera is directly plugged into a computer’s video capture card. The card is what primarily does the conversion. Alternatively, the recording can be stored using a digital video recorder (popularly referred to as a DVR). DVRs are more designed for the storage of camera footage compared to most computers and this greatly reduces the maintenance they require. However, if the DVR fails then replacement is the only available option.

Digital wireless surveillance cameras

Computers are able to directly store footage from digital wireless surveillance cameras and this nullifies the need for a video capture card. A 5:1 ratio is usually used to compress the signal. However, it should be noted that it is possible to achieve higher quality, but uncompressed digital data tends to consume a lot of hard drive space.

Wireless Surveillance Cameras with RCA Receivers

This type of camera is quite easy to set up and enables people who are conversant with RCA cables to establish a connection between a hidden camera and a standard television set, VCR, DVR or any other similar device that supports RCA cable input. This type of camera can be used in the following steps:

  • The hidden camera should be placed in the target area.
  • The power cord should be plugged in.
  • The receiver should then be placed at a distance not exceeding 300ft away.
  • The adaptor should then be plugged into the receiver and ultimately to the wall.
  • Finally the RCA connectors should be plugged to the TV set.

Wireless Surveillance Cameras with USB Receivers

These are digital cameras that facilitate live video streaming to a PC and remotely viewing it from anywhere on the globe. It is characterized by encrypted transmission so that feeds are perfectly secure. What it means is that the camera and the USB transmitter are paired limiting their use to one at a time.

Wireless Surveillance Cameras with Wi-Fi and IP Receivers

This type of receivers facilitate the viewing of feeds on the internet by simply typing the IP address of the camera to any web browser. Their set-up is a bit complicated compared to other types. A computer for purposes of viewing feeds is not a necessity as it is the case in USB receivers. It also has the option of connecting to vcr, dvr, television set through RCA cables making it seem like having two receivers in one.
