Home and business owners lack the necessary skills and equipment to design and implement effective surveillance systems. Some of the common CCTV problems that property owners face have to do with improper installation of power supply and CCTV cabling. Therefore, consumers should engage reputable CCTV installation companies such as I-Tech Security to help prevent these problems.
Tips for Effective CCTV Installation
1. Power Supply
The power supply is an important aspect of any CCTV security system. The tips below will ensure that your CCTV equipment operate at their optimal, prevent damage to the equipment, and avoid the risk of fire.
- Ensure that the CCTV equipment you buy is of the right voltage and current rating, as the power supply source. Additionally, the power supply should be regulated, with tolerance that doesn't exceed 5% of the required voltage.
- The installer must observe the polarity when connecting security cameras and other CCTV equipment to the power supply.
- Each power supply unit should offer spare capacity of at least 40% to prevent voltage loss and over-heating.
- Do not operate CCTV equipment on the same power circuitry as large motors, generators, compressors, and elevators.
- Proper ventilation and cooling should be provided for all power supply units.
Using the wrong cable length, or laying CCTV cables in the wrong way could lead to signal and voltage drops, which ultimately affect the performance. Below are some considerations to eliminate CCTV cabling problems.
- The CCTV installer must ensure they use suitable cable lengths.
- Factors such as over-tightening cable ties, cable joins, and sharp bends should be avoided at all costs.
- Cable runs should be done away from high current AC power lines, if possible. If the power lines cannot be avoided, then the installer must ensure that the video cables do not run parallel, as this creates noise and interference.
- Installers must use the appropriate wire-stripping and crimping tools. In addition, the crimped area and bend radius of the wire should be protected using rubber boots.
"¢ All cabling should be clearly marked to avoid confusion after the CCTV installation is complete.
