What People Say about the Security System?
Cameras can record images up to twenty or thirty feet away, which is not very bad. The night vision images are black and white. You can get snapshots directly to your email account. Some people say that the system can be great for keeping an eye on your yard or your parking lot. Others say that they could even succeed capturing orbs in an attempt to make their first paranormal investigation videos. At night, human shapes can be seen even at 300 yards and you can make the difference between trucks and cars.
Those who already got the product say that the camera detail is not the one of a high definition security system meant for commercial applications. But, the cameras can be great for home use, or for a small store or shop. Also, the cameras can be replaced if you are not satisfied with the detail.
After installation, you may have to play with different settings and see how the system actually works. You may also have to set the time and date, motion sensors, or the recording. These settings will surely not be an issue. At the price of this camera, many people can have too high expectations and this is the reason for which there are some minor complaints on the web.
