15 top tips for maintaining your home video surveillance system


In order to ensure that you home security system keeps functioning optimally, you’ll need to schedule a regular CCTV maintenance checklist. This will help protect your investment while ensuring that you get the best possible performance from your security system. Below are the 15 tips for your security camera maintenance.


1.Clean camera lenses

Check your outdoor and indoor camera lenses to ensure they are always clean. Look for smudges, dust, water-spots and other undesirable elements. Your camera won’t get clear shots if your lenses are smudged or dirty. You should ideally start by using a compressed air can to blow the lens and remove all loose debris before using a microfiber brush to wipe the lenses very gently.

2.Trim the landscaping

Check all your outdoors camera view to make sure that all provide a clear view. Keep bushes, vines, trees and other plants near the cameras trimmed to prevent them from obstructing the camera.


3.Check the camera’s housing

The camera’s enclosures should remain water proof and you can check this by opening your security cameras’ housing to check for signs of water, dirt and condensation. This way, you will know whether the enclosures are still protecting the cameras from rain and wind.


4.Check for corrosion

Check out all connectors for signs of corrosion. If you found any corroded one, replace it immediately since it can cause the rest of the equipment to short out.


5.Ensure that all cables are connected securely

Check all cable connectors, including those connecting the monitor, DVR and security cameras to ensure that they are all receiving power. Also check the cabling for any signs of wear and tear, replace any exposed wire immediately.


6.Check the power supply

Check the power supplies to your home video security systems to ensure that there is no loss of power due to storms, tampering, brownouts or other unwanted events. Check your UPS to ensure the battery are fully charged and don’t show any warning lights. You may also want to check that your surveilance cameras are receiving their recommended power requirements using a voltmeter. Otherwise, the camera may fail rapidly and it is always cheaper to replace the power supply than buy a new security camera.


7.Dust your DVR

The DVR may collect a layer of dust over time, and this must be wiped of regularly to prevent it from affecting the DVR’s performance. Use a microfiber cloth to wipe your DVR or use a blower to dust the crevices.

8.Emptying the hard drive

A large hard drive is needed to record and store a lot of data, but even one as big as 1 Terabyte will only store about 3 weeks of full motion video from a single camera. This means that you have to periodically back up and delete the video once the hard drive fills up. However, this may not be easy if you are using ultra-modern surveillance kits from companies like Annke that includes aps that allow remote storage and viewing.

9.Verify the recording function at least once per week

Have a reminder to check on the camera system recording ability each week. It is always important to find out if there is something wrong with the system before a major security incident actually occurs, only for you to find that you have to useable footage of the incident.


10.Periodically review camera position set ups

This should be done to ensure optimum location and camera focus. You may include an extra camera to capture “fill the frame” images of potential suspects as they move about your home in addition to the ones that cover the whole scene.


11.Check the lighting

Ensure that important areas have enough lighting to illuminate suspects for easy identification. You may have to install an additional camera to capture fill-the frame images of suspects as they move about the home in addition to those that cover the whole scene.


12.Check and remove any banners, posters etc. that obstruct the camera’s view

The camera’s line of sight should remain unobstructed, and obstruction typically happens when banners or posters are placed in front of hidden camera locations by other individuals.


13.Set the correct date and time

On a daily basis check to ensure that the correct date and time are generated by the DVR and displayed on the monitor. Brief power outages may make it necessary for the time and date to be set.


14.Post signage

Making a small investment in professional signage can help mitigate risks by confirming that you are in fact using video surveillance around your premises. Visible signage is the first lie of deterrence and helps enforce your property boundaries.


15.Secure a comprehensive maintenance coverage that includes inspection, cleanings and extended warranty coverage by professionals

A number of service level agreements to maintain your home video surveillance system are available and they may include loaner gear, emergency response, and instant availability of replacement parts.


In a word


Maintaining your home or business premises takes time, but keeping it from would-be criminals is an even bigger challenge. Your video surveillance cameras need regular maintenance to ensure a clear picture, uninterrupted feed and wholesome coverage of key areas. It is important to create a CCTV maintenance checklist for yourself so that you don’t miss out the CCTV maintenance as it is just as important as the safety of CCTV installation.
