Hidden cameras are an important component of a surveillance system. They can record sureptitiously and can be an effective means to monitor activities and provide evidence in case of a crime or a violation. Get to know the different types of hidden cameras to determine which one is right for your needs.
A nanny cam is a type of hidden camera that generally has the most basic functions. It’s single focus, stationary and has low to average image quality. The nanny cam is a good choice for a hidden camera meant for general use such as home or office monitoring and surveillance. It works very well for a limited area, such as a small or mid-sized room but may not be recommended for large areas. The image quality is often not sufficient to allow the user to obtain a sharp image from afar, say — 20 to 30 feet away. For closer monitoring though, the nanny cam works very well.
The nanny cam is also the type of hidden camera that is usually disguised as something else. It could be installed on a wall clock, for example, or a stuffed toy or even a picture frame.
Portable hidden cameras
This is a type of hidden camera that is smaller than the usual, which means it can be installed in just about anything. A portable hidden camera can also be worn, which makes it ideal for personal or face-to-face monitoring or sting operations. These days, hidden cameras of this type are also equipped with audio capability in order to capture sound.
Usually, the hidden camera contains a transmitter which sends signals to a remote receiver. This allows for a real time live feed of the images and audio captured by the camera. In some models, the hidden camera comes with an SD card that will record images and audio digitally. These can later be uploaded onto a computer for viewing.
Sensor-driven hidden cameras
Some hidden cameras, particularly those used for home or office security, are equipped with a built-in sensor. This sensor detects movement, which makes the camera ideal for 24/7 surveillance. It will only turn on if and when movement is sensed. Otherwise, the camera remains on standby.
In terms of energy use and efficiency, the sensor-driven hidden camera is an excellent choice. It will only record if activity occurs. It can also be set up to set off an alarm if motion is detected, alerting security officers or homeowners.
Night vision hidden cameras
Night vision hidden cameras are equipped with infra red technology. This allows the camera to record images even in low light conditions. Some high-end models can even record even in the complete absence of light, which makes them ideal for areas such as the backyard, garages, parking lots and store rooms.
Night vision hidden cameras can be excellent for surveillance or home security needs because they do not rely heavily on a strong source of light just to record any activities. As such, it can be used night or day without anyone knowing that it had been installed.
