Tips for Buying a Hidden Camera: Important Features to Look For
A hidden camera can be a very efficient device to use for security purposes. It has been very effective for households and businesses that require evidence of a certain act, violation or even crime. Hidden cameras are getting smaller and can be mounted on just about anywhere or anything. However, not all hidden cameras are built alike. If you want to be able to tell a quality device from an average one, here are some features you need to look for:
Resolution
Resolution refers to the capability of the camera to produce a clear, sharp image. This is expressed in figures. The higher the number pertaining to the resolution, the sharper and better-looking the image will turn out.
When buying a hidden camera, look for models that have a resolution of AT LEAST 400 lines. This should give you sufficient image clarity even from a distance. If you want the sharpest image, go for 470 resolution lines or higher. Just remember, though, that the higher you go, the more expensive the unit will be.
Lighting
A camera works by processing and capturing ambient light. This is why in less than ideal conditions, a digital camera will automatically fire off a flash to illuminate the subject.
When buying a hidden camera, check its ability to manage light, expressed as the LUX rating. In this case, the higher the rating, the less the camera is capable of producing a good image in the absence of light. So if you will be using the hidden camera in low light conditions, look for a .05 LUX rating. Lower ratings mean it can operate efficiently in semi-darkness. For total darkness, you might need a camera with a night vision.
Range of transmission
A hidden camera will work with a receiver, which will process the video images being captured by the lens. Determine how far away the receiver will need to be from the hidden camera. Depending on the camera’s transmission range, the receiver could be from as near as the next room or as far away as the next building a few thousand feet away.
Wireless or wired?
That really depends on where you intend to mount the camera. A wired camera will be physically connected to a recorder such as a computer or a VCR using a cable. A wireless hidden camera, on the other hand, is independent but will run on batteries. If you intend to record for longer periods of time, a wired camera may be better. For shorter periods of time (or at least for as long as the batteries will hold up), a wireless hidden camera will be ideal.
