When you need to display images form a security camera, sometimes and often you couldn´t do it. Security cameras to surveillance or access control need a maintenance to dicrease the risk and failures. We´re going to show you the common failures that we use to find.
ELECTRIC SUPPLY FAIL
Cameras and recordings need a electric supply. If the supply system fails, it couldn´t store the images.
Our suggestion is that you install a SAI ( Ininterrupted Supply System) that gives electricity to recording when there is a electric failure. Also you will get to keep safe the electronic devices.
HARD DISK DAMAGES
Hard Disk stores the images, it´s call HDD (Hard Disk Drive) and ithas a limit capacity. When it´s full, the images are rewriten wih the new récords. The number of rewritings is variable and as you know, everything has a lifetime. So sometimes the system is connected, cameras could be displayed but they aren´t been recording in the hard disk.
FAILED SECURITY CAMERAS AND DIRTY LENS
Recording takes images from different installedcameras. It processes and stores them during programmed time. Sometime the problem could be caused because the camera hasn´t electric supply or the energy power is damaged.
Sometimes you could find dirty or unfocused lens. It happens when cameras are localed on outside areas. You have to check and clean frecuently the lens to get always a good quality images.
It´s usual that security cameras are connected to recordings by a 5/6 wire or UTP wire. These wires could be installed inside a pipe and to cross though union box. Humidity could damage, passing of time, the material of wiring.
Also, it´s usual that rodents brake the wiring and they leave the recording without connection .
DAMAGED POWER SUPPLY
Security cameras are supplied by low voltage. It means that we need a little trasnformer between the outside power supply and our device. Sometime, the problem comes from this transformer, like everything it has a lifetime too.
For all these reasons we suggest to do a regular and programmed maintenace of your CCTV systems. If yoy don´t do it, maybe when you´ll need to get some images, your equipment shall not to be recording.
