By following a few basic guidelines and using some basic test equipment, even a novice technician can more easily solve CCTV system problems. Whether the problem occurs during initial system installation or after, most installation and service managers fear troubleshooting procedures.

If you need help during the installation process, please call to speak with our support. Tri-Ed distributes CCTV, IP video, access control, fire, intrusion, sound, communications, structured cabling and home automation products.This step is especially important when systems include different monitoring locations. Following the video and data paths of an entire system is essential for proper troubleshooting procedures. Understanding these paths will help determine, for instance, the proper terminations of all signals. Remember, it is much easier to understand a system on paper than to understand that same system in the field. Examining the diagram also takes less time than walking through the system in the field. Some of the following questions, particularly the first few, may seem very basic. However, they are the perfect starting point for troubleshooting any system. How old is the system? The average life of most system components is about seven years. Components such as pan- and- tilt units, analog recording devices and monitors have shorter lifespans and will require more maintenance. Has the same problem previously occurred? Electronics and electronic equipment are logical; human behaviour is not. If a previous technician has shorted a terminal with a screwdriver or adjusted the control potentiometer without knowing the functions, it can add to your headaches. So it is a good idea to ensure no one else has tried to fix the problem. If you find someone has, you must perform a complete check of all connections and settings before moving forward. It may also be a good idea to speak with the previous technician regarding the problem, but proceed with caution. One person's impression of the system trouble may or may not be accurate. System technicians must rely on the information at hand, but they must also verify this information. Assumptions have led to excessive troubleshooting time and many failed attempts at system repair. Asking the following questions can help limit the possibility for unwarranted assumption. What type of video cabling is installed? Are there video amplifiers installed in the system? Problems associated with power, power surges and excessive AC voltage range from 2. That means only a maximum of 1. The rest are caused, for the most part, by human error. However, if you supply your service technicians with proper tools and education you will find that your return on investment both in time and in money will far exceed expectations. Technicians must be able to properly evaluate the symptoms and make the correct decision for system repair. Troubleshooting requires some basic tools, which range from a simple screwdriver to an oscilloscope. The following is a basic list of equipment useful for system troubleshooting. Volt- ohm- meter (VOM). MHz). Test monitor. Simple mistakes, such as forgetting to add 7. Most manufacturers now suggest the appropriate cable and connector types for their equipment. The standard recommendation for video cable is cable with copper centre conductors and a minimum of 9. The use of aluminium- shielded cable for video is now forbidden by all system manufacturers using baseband signals. Many manufacturers also state that only two- piece or three- piece crimp- on BNC connectors should be used. The days of BNC twist- on connectors are long gone. The main reason is the increasing use of digital equipment. Digital equipment in most cases requires smaller operating ranges than its analog counterparts. Therefore, many manufacturers have shortened their operating cable distance to conform to the new digital requirements. All of this will affect installation as well as system troubleshooting parameters. For the most part, these manufacturers have found that their training has helped reduce service calls related to simple system problems. This reduction has freed up their technical staff to answer the more complex questions, which improves their overall customer service programs.
