The amount depends on the compression ratio, Security cameras can generate a large amount of data. Setting up your camera to use motion detection can significantly reduce storage usage. The required amount of storage is dependent on your camera’s image resolution, frame rate,Ĭompression ratio and days of retention. However, storing data in this manner leaves it susceptible to tampering and damage by intruders.įor better protection and security, offsite storage is the best solution.

Those cameras use an infrared spectrum of light at night and can take pictures of objects in the dark.

It is recommended that you use a camera with night vision capability. One of the main usages of a security camera is to monitor night-time scenes. Motion detection is very useful if you want to significantly reduce bandwidth and storage usage. Minor scene changes will be ignored and only scene changes that reach the “threshold” will be recorded. Many security cameras allow you to configure a “threshold”. Many security cameras can only detect image changes.Īs minor scene changes can occur due to events such as natural light changes or wind changes, Motion can be detected by image changes or sound changes. Many security cameras now support motion detection - a technology that triggers recording only when something changes in the scene. If a security camera records data onsite, both the camera and the recorded data can be destroyed – by intruders, burglars, or anyone else who wants the data gone forever. They are also easily susceptible to tampering. They can fail due to dust, smoke, fog, loss of power, or damage. Security cameras themselves are not completely secure.
