Cameras are designed to work in a variety of weather conditions, but they can be damaged by severe weather. High winds, heavy rain, and lightning can all causes video loss in security cameras.
Fix: Extreme Weather Conditions
Replacing a camera that is damaged by harsh weather conditions is pretty much your only option. You can try to repair the camera yourself, but it’s generally not worth the effort.
Prevention: Extreme Weather Conditions
To prevent damage from extreme weather conditions, make sure your cameras are properly rated for the temperature or conditions where you plan to install your cameras. If you live in an area with severe weather conditions, consider investing in a weather-tolerant security cameras.
Cause 7: Poorly Designed Security Cameras
Some security cameras are just poorly designed and susceptible to video loss. In general, lower-quality security cameras are more likely to experience video loss than higher-quality cameras. This is because lower-quality cameras often have cheaper components that are more likely to fail.
Fix: Poorly Designed Security Cameras
There’s not much you can do to fix a poorly designed security camera. The best course of action is to replace the camera.
Prevention: Poorly Designed Security Cameras
To prevent this problem, make sure you buy security cameras from a reputable manufacturer. Avoid buying cheap, off-brand cameras. It might seem obvious, but it’s also a good idea to read online reviews and do some basic research before you make a purchase.
Cause 8: Low Bandwidth or Weak Internet Signal
If you’re using an IP security system or Wi-Fi security cameras, a low bandwidth or weak internet signal causes video loss in security cameras. This problem is more common with Wi-Fi security cameras, as they rely on a strong signal to function properly.
Fix: Low Bandwidth or Weak Internet Signal
The best way to fix this problem is to move your security camera closer to your router or boost the signal with a range extender. You can try increasing the bandwidth of your internet connection if you’re using an IP security system.
Prevention: Low Bandwidth or Weak Internet Signal
To prevent this problem, make sure your security camera is placed close to your router. If you’re using a Wi-Fi security camera, consider buying a range extender to boost the signal.
Cause 9: Faulty IR Night Vision LEDs
IR LEDs are used in security cameras to provide night vision. These LEDs can sometimes stop working, causing video loss at night.
Fix: Faulty IR Night Vision LEDs
Again, the best course of action is to simply replace the entire camera. Attempting to fix a faulty IR light is likely not worth the time, effort, and expense.
Prevention: Faulty IR Night Vision LEDs
There’s not much you can do to prevent this problem, but buying a high-quality security camera from a reputable manufacturer will decrease the chances of it happening.
Cause 10: Equipment Compatibility Problems
Sometimes, video loss can be caused by compatibility problems between your security camera and other equipment. For example, video loss might occur when combining security cameras of higher resolution such as 4MP, 5MP, or 8MP with an NVRs or DVRs designed to only decode 2MP cameras.
Fix: Equipment Compatibility Problems
If you’re experiencing video loss due to compatibility problems, the best thing to do is upgrade your NVR or DVR to a model that is compatible with your security camera.
Prevention: Equipment Compatibility Problems
To prevent this problem, make sure you buy equipment from the same manufacturer. That way, you can be sure everything is compatible and won’t cause issues.
Cause 11: IP Address Conflicts
Video loss can occur in an IP security system if two devices have the same IP address. The two devices will be fighting for the same IP address and won’t be able to properly communicate with the base station.
Fix: IP Address Conflicts
To fix this problem, you’ll need to log into your router and change the IP address of one of the devices. Alternatively, you can use a tool like DHCP reservations to assign a static IP address to one of the devices.
Prevention: IP Address Conflicts
Check all the devices on your network and make sure they all have individual IP addresses. Change the IP address of any device with a duplicate IP address.
Cause 12: Power Surge
A sudden power surge can damage your security camera and cause video loss. Power surges are caused by a sudden increase in voltage. They can happen for a variety of reasons, including lightning strikes, faulty wiring, and power outages.
Fix: Power Surge
Unfortunately, there’s not much you can do to fix a security camera that’s been damaged by a power surge. Your best option is to replace the camera.
Prevention: Power Surge
Surge protectors can help protect your security cameras from surge protectors. Other preventive measures include proper grounding and even powering down your equipment during extreme thunderstorms.
Cause 13: Hardware and Firmware Issues
Occasionally, video loss can be caused by hardware or firmware issues. Firmware is the programing that controls the camera’s hardware. Over time, firmware can become corrupted, causing problems with the camera’s ability to record video.
Fix: Hardware and Firmware Issues
Upgrade the camera’s firmware is your best fix for this issue. Upgrading usually involves simply downloading the latest firmware from the manufacturer’s website and following their instructions.
Prevention: Hardware and Firmware Issues
There’s not a whole lot you can do to prevent this problem. Buying a high-quality security camera from a reputable manufacturer will decrease the chances of it happening though.
Cause 14: Broken Camera
Obviously, a broken camera can’t record video. If your security camera is physically damaged, it will need to be replaced.
Fix: Broken Camera
Replacement is really your only option here. Fixing a broken camera is usually not worth the effort and expense.
Prevention: Broken Camera
Equipment has a shelf life, but you can still do your best to make sure your equipment lasts for as long as possible. Regularly cleaning and maintaining your security cameras will help them last longer. Check cables for wear and tear, and use protective measures such as surge protectors and lightning rods to protect your equipment from the elements.
Cause 15: Vandalism
Vandals can damage or destroy your security cameras, resulting in loss of recording. In some cases, vandals may also damage the wiring, causing even more problems.
Replacement is the only option for severely vandalized security cameras. Depending on the extent of the damage, you may also need to repair or replace the wiring and the mounting hardware.
Vandalism can be prevented by keeping your security cameras well hidden and out of reach. Placing cameras in hard-to-reach places or using vandal-resistant materials can also help keep your cameras safe from vandals.
Video loss can be caused by a variety of factors, including power surges, hardware and firmware issues, and vandalism. In most cases, the best way to fix video loss is to replace the security camera. You can also take preventive measures to protect your equipment from damage, such as using surge protectors and hiding your cameras from view.
Many video loss issues are caused by poor installation. If you’re not sure about installing your own system, make sure that the system you buy is installed by a professional. If the camera monitors are showing black screens, turn on and off, or are displaying moving lines on the screen, it’s likely the installation was not done properly.
