Dust, humidity, or small insects can accumulate on the lens and housing, reduce the quality of the recording. According to the Security Industry Association (SIA), a camera that is rarely cleaned is at risk of experiencing fogging In the lens, especially in damp areas.

In addition, dirt that sticks for too long can scratch the lens layer, making the image look blurred permanently. If it’s like this, inevitably have to change the lens or even the whole unit. In fact, the cost of repair can be more expensive than just routinely cleaning it.

Environmental factors also influence. Outdoor cameras are exposed to rain, heat, or pollution more vulnerable to damage. If the housing is not waterproof or there is a small crack, water can seep and damage the electronic components in it. Some manufacturers such as Hikvision suggest periodic inspections to ensure the camera seal is still tight.

What is often forgotten, cables and connectors also need checking. A peeled cable or loose connector can make the camera die suddenly. Simple inspections such as ensuring that the cable is not bitten by mice or bent can avoid big problems.

1. Microfiber cloth – This fiber -free soft fabric is safest for the lens. Avoid tissue or rough cloth that can scratch the surface. Lensrentals recommend microfiber because it is effective in removing dust without chemicals.
2. Blower (Small Dust Suction) – To clean coarse particles before wipe. Pressurized air can push dirt without touching the lens. But be careful, don’t use a high pressure wind compressor that can damage the components.
3. Lens cleaning solution – Special camera lens cleaning fluid, not alcohol or ordinary glass cleaner. Products such as the Zeiss Lens Cleaner are formulated so as not to damage the anti-reflective coating on the lens.
4. Cotton Bud – Useful to reach a narrow angle around the lens or housing. Make sure the cotton is not easy to fall out so as not to be left behind.
5. Fine brush (brush) – A small brush with soft fur can sweep the dust on the outside of the camera before cleaning further.
6. Screws and small screwdrivers – If you need to open a housing to clean the inside, make sure you have a screwdriver that matches the camera screw.

Never use ingredients such as wet tissue, soap, or household spray – the chemical president can damage the lens layer. With the right tool, CCTV camera maintenance So it is more effective and safe.

Steps to clean the CCTV lens safely

Cleaning CCTV lenses requires special techniques so as not to damage it instead. Follow the following steps for maximum results:

1. Turn off the camera and remove the power – Safety First! Unplug the power supply or disable it via DVR/NVR to avoid short circuit. Axis Communications emphasize the importance of ensuring the camera is completely dead before cleaning.
2. Clean the dust with a blower – blow the surface of the lens and housing using a small blower or a smooth brush. This eliminates coarse particles that can scratch the lens when wiped.
3. Spray cleaning fluid to the cloth, not directly to the lens -Drop 1-2 times the lens cleaning solution to the microfiber cloth, then rub the lens in a circle from the middle outside. Don’t press too hard – enough soft movements.
4. Stubborn stain tackle with cotton bud – For dirt attached to the edge of the lens or housing gap, use a cotton bud that is soaked in a little cleaning fluid.
5. Re -check after dry – Make sure there are no fingerprints, fabric fiber, or the remaining liquid. Past stains can reduce the clarity of the image.
6. Test back after turning on – Reinstate power and monitor through the monitor whether there is distortion or blurry point. If there are still problems, you may need a deeper examination.

Avoid cleaning the lens in direct sun -sun -hot – it can dry too fast and leave the residue. If the camera has an automatic UV or Wiper protector (like a model from Dahua), make sure the features function normally after cleaning. CCTV camera maintenance The truth makes the recording remain sharp and durable.

Tips for caring for a CCTV camera to last

In order for the CCTV camera to remain durable and function optimally, routine maintenance is more important just to clean the lens. Here are tips from practitioners:

1. Routine cleaning schedule – Clean the lens at least once a month, or more often if the camera is installed in a dusty area/near the highway. Bosch Security recommends a weekly visual inspection for outdoor cameras.
2. Check housing and cable -Make sure the anti-water casing is still impermeable, especially after heavy rain. Small cracks can be a moisture entry path. Wrap the cable with PVC Conduit if exposed to extreme weather.
3. Firmware update – Software updates from producers (such as Hikvision) often include improvements to stability that extend hardware life.
4. Set the position for minimal disturbance – Avoid points that are directly exposed to day sunlight (risk of overheating) or the area where birds often perch (dirt can accumulate fast).
5. Use Surge Protector -Electric surge is a secret camera killer. Install a small stabilizer or UPS for extra protection.
6. Periodic Night Vision Test – Clean the IR filter with alcohol cotton if the infrared image becomes noise or spotted.
7. Record the treatment history – Document when the last to be cleaned/repaired. This helps detect damage patterns.

For old cameras (over 5 years), consider replacing components such as adapter power which is often the cause of early failure. CCTV camera maintenance What is consistent can save premature replacement costs up to 70% according to industrial data.

Common mistake in cleaning the lens

Many people are not aware of making fatal mistakes when cleaning CCTV lenses. The following things that actually damage the device:

1. Using a tissue or rough cloth – Ordinary tissue contains wood fibers that scratch the lens layer. Canon’s Official Guide warns that micro scratches reduce permanent image clarity.
2. Direct spray to the lens – Sprayed cleaning fluid can immediately seep into the sidelines of housing and damage the circuit. Always apply to the microfiber cloth first.
3. Wear alcohol or glass cleaning -Hard chemicals such as ammonia erodes anti-reflective coating. Producers like Sony suggested that only using a special pH-network solution of the lens.
4. Pressing too strong when wiping -Excessive pressure can cause the lens to shift from its position, especially on PTZ (Pan-Tilt-Zoom) cameras.
5. Ignoring the initial dust – immediately wipe without blowing dust first the same as rubbing sand on the surface of the glass.
6. Clean when the camera is still hot – The lens that has just been exposed to the sun or works long is more vulnerable to cracking due to sudden temperature changes.
7. Wear a used cloth – Fabrics that have been contaminated with oil or other dirt will only spread stains.

Small mistakes like this often cause fogging, excessive glare, or even sensor damage. According to the survey Routinely, is the key to maintaining your security system performance. From the correct cleaning to periodic checking, these simple steps can extend the life of the camera and ensure the recording remains clear.
