PTZ dome cameras are hemispherical shaped cameras that are normally installed on the ceiling, but can also be mounted on a wall. The image is more realistic and defined than in thermal cameras, since we see what the lens captures, without any process of artificial image formation.Ĭonventional cameras can be of different resolutions and ranges, depending on the quality of the lens. Thanks to this thermal image, the guards can sufficiently identify whether it is a person or an animal, and prevent possible unauthorized entry within the security perimeter.Ĭonventional video security cameras capture the image using a video lens and normal photography. Not needing lighting, they are ideal for discreet surveillance. These cameras are ideal for use in low or no light conditions. Thermal cameras capture heat radiation emitted by bodies and with it form an image. In principle, surveillance cameras could be classified into three groups: There are different types of outdoor security cameras. This fact is due to the opening of the diaphragm of the camera and the depth of field. On the other hand, if we focus during the day, we run the risk that the image is out of focus at night. It may be that the cost of working at night is greater in time (the technician will not take the same as in the day) and in budget (you have to pay extra overnight), but in the long term it will be much better. If we adjust the focus of a camera at night we have the certainty that it will look good during the day. We also have to check the connectors that break down or loosen over time, also causing that flicker that we are talking about. This causes the continuity of the electricity supply to be inadequate, which will end up producing the famous flickers of the surveillance camera. In many occasions, the cables can suffer deterioration due to the passage of time and inclement weather, also due to accidental cuts. We cannot ignore that the failure is caused by deterioration of the cables or by connections in poor condition. That will also cause an intermittent flickering. If not, it may happen that the correct power supply voltage is not reached. The power supply must be dedicated exclusively to that camera. Just as the 12-volt transformer fails, there may also be a problem with the camera’s power supply. That power issue causes intermittent on and off that looks like a blink. These transformers deteriorate over time and the proper infrared voltage does not reach the camera. The cameras normally operate at 12 volts, so they are equipped with adapters to pass the supply input voltage to that voltage. Sometimes the flickering can be due to a 12 volt transformer failure. In the alarm center this is perceived as flashes. In this way you can capture images in poor lighting conditions.īut if there are light sources close to the camera, it can destabilize the camera’s infrared system, which will start to flicker because the light source causes the camera to frequently turn on and off its infrared. The cameras are equipped with an infrared system that is activated in low light conditions such as when night falls. Light sources are one of the most common reasons that security cameras flicker at night. Some reasons to know why my security camera blinks at night are: We will also give you some tips and useful information for the correct operation of your security cameras.

In this post we will try to answer that question.
