How Do Nanny Cams Work

how do nanny cams workAlthough the options may seem daunting at first, choosing the right nanny cam(s) for your situation can be quite simple once you understand the basics of how they work.

Our main four types of cameras are wired, wireless, USB receiver, and with built-in DVR.  Let’s take each one, in turn, starting with our DVR nanny cams.

DVR Nanny Cams

Our nanny cams with built-in DVR recorders are very popular due to the fact that no additional accessories or equipment is needed.  The camera and the recorder are housed in the same unit, where the camera records directly to an included SD card.

Recordings can later be viewed either by using the included RCA cable to hook the camera up to a television set, or you can simply remove the SD card and plug it into your computer, allowing you to watch the recordings there.

USB Receiver With Remote View

These cameras wirelessly transmit their video signal to a nearby computer (computer not included), where the USB receiver is installed, recording the video output directly to your computer.

Even more exciting, the Remote View software allows you to log in and view a live feed of your camera from any computer with an Internet connection!

The USB Receiver uses a digital wireless signal, virtually eliminating wireless interference, which can be experienced with traditional wireless units.

The system also encrypts the video signal, preventing unauthorized interception of the wireless video signal.

Wired and Wireless Nanny Cams

Our other two types of cameras (wired and wireless) require a recording device in order to record video.  You have several choices here, allowing you to record to a VCR, embedded DVR (similar but different than the type of DVR you get through your cable company), and through a USB computer adapter.  We offer several choices in embedded DVRs and USB computer adapters here – Recorders.

You’ll also notice another device called a “Quad” that is also listed there.  Quads are only needed for VCRs, and their function is to divide the picture into 4 frames, allowing for up to 4 cameras to record onto a single tape.

So what’s the difference between wired and wireless?

Wired cameras require a video cable to run from the camera to your recording device.  This can possibly require drilling into a wall or ceiling in order to hide the wire, depending on which camera you’re using and where you install it.

Wireless cameras use an included transmitter and receiver to wirelessly send the video from the camera to the receiver. This then plugs into your recorder of choice.  Standard wireless transmitters have a range of up to 1000 feet. Some cameras have the HP (high power) option, which has a range of up to 2500 feet.

Do I need to run a power cord?

It is also important to keep in mind that just because a camera is “wireless” doesn’t mean that the camera does not need to be plugged into an electrical outlet.

Below are nanny cameras that use 8-hour rechargeable battery packs:

  • Screw Hidden Camera
  • Tissue Box Hidden Camera
  • Mirror Hidden Camera
  • Air Freshener Hidden Camera


So as you can see, it’s a lot easier to decide which recording solution is the right one for you.
