Usually, CCTV camera system’s are reliable and trouble free, but they can develop problems such as flickering which can be annoying and spoil the quality of your video recordings.
Some of the main reasons your CCTV camera system is flickering are:
- Faulty or unplugged cables
Faulty cables can cause flickering, so make sure they’re not damaged. An old spliced could over time become unreliable and rodents are fond of chewing cables.
Check that all plugs are secure and plugged in tightly
- Anti-flicker Software
Check that your anti-flicker software is turned on, updated and functioning correctly.
Reset it by turning it off and waiting a few seconds, then turning it on again
If you find that your outdoor camera flickers mainly at night it could be interference from your lights. LED bulbs flicker on and off very quickly, we do not notice, but your CCTV camera system might and give you an image that is flashing on and off.
You can test this by changing your light bulbs from LED to incandescent or finding an alternative light source. Closely monitor your images during the day, if they are still flickering, then there is another problem
- Power Frequency
If you purchased your CCTV Camera system locally from a reputable company you should not have a problem with the local power frequency. But, if you purchased your system overseas you may find it runs on a different power frequency as different countries use different power frequencies. Some brands of CCTV camera systems are compatible while others are not.
Your CCTV camera system may still work with a different frequency, but might be experiencing flickering or other problems because the timing of your camera taking an image can get mixed up or out of sync with the light or when another piece of your CCTV camera system is in a different phase.
- Power Supply
Your CCTV camera system can use a lot of power to run, especially if you have auto zoom and rotating cameras. Each separate part of your CCTV camera system will have its own power supply, but you need to take into account the peak power each component requires.
Each component of your CCTV camera system will have marked on it the wattage rating it requires, add up all the peak wattage requirements of all the equipment plugged into the circuit that supplies their power and check to see if that circuit can cope with the total.
Normally the 130% rule applies where you should have a total wattage capacity on the circuit of 130% of the total combined equipment. If you find that the amount of wattage needed is grater that the circuit capability then you will have an overload condition.
In this case, you will need to use another circuit for some of the equipment so neither circuit is in an overload condition. Night vision cameras can use a lot more power when operating at night compared to day time use so if your images only flicker ay night this could be your problem
CCTV camera systems can be sensitive to the power frequency in your area and the pulse of LED lights. If all cables and connections are in good condition check your anti-flicker software and that you have not overloaded the power circuit you’re connected to.
