Video loss from CCTV cameras comes in many forms. Images are poorly transmitted to recording devices, are lost once recorded, or are simply not captured or poorly captured.
Many users have tried and used different methods to solve the video loss problem, but without success. Today we share some of the best practices for preventing video loss from CCTV cameras.
Insufficient food
Insufficient power is very often the cause of loss of video on one or all CCTV cameras, loss of CCTV at night, loss of video signal on the screen, blackening of the camera. night or activating / deactivating the flickering of the video.
Here are some common reasons why the power of CCTV cameras is insufficient:
- Loose cable connection.
- PE switch or PE injector.
- The cable is too long, or one cable provides too many cameras at a time.
- Defective power cables (old, damaged, degraded or cut).
A loose cable connection, for example between a DVR / NVR with cameras, between CCTV cameras and a monitor or screen, AC adapter, or a possible loose connection in the camera’s power supply can result in loss of video.
Quick repairs:
Double check all power connections, power splitters, cable connectors, etc. to exclude connection problems. Toggle the ports to make sure the DVR / NVR port powers the cameras.
Connect the IP cameras directly to the NVR (if applicable) instead of a PoE switch, as the PoE switch may not provide insufficient power to the IP cameras.
Check in particular IP PTZ cameras or infrared night vision security cameras, which consume more electricity than those which do not come with PTZ or night vision technology.
If PoE switches or PoE injectors are required, be sure to choose the correct PoE switches or injectors.
In addition, try to use shorter BNC or Ethernet cables to power the surveillance camera system and avoid using poor quality extension cables or extension cables.
If you are using battery-powered security cameras, make sure the battery is not discharged or charged via an AC adapter or solar panel.
Power peaks and interference
Another risk is the power peak.
Doing so could cause sudden video loss to security camera systems in Chicago, all CCTV cameras, a black screen, a camera with the electrified surface, the camera with a vertical / horizontal line, or serious damage to the camera circuit board or to other components.
Here are some common reasons explaining my power spike and interference:
- Mounting the security camera on a metallic / conductive surface.
- Lightning.
- Strong interference caused by nearby electrical equipment.
Quick repairs:
To resolve this issue, try using surge protectors or lightning protection to protect your CCTV cameras from lightning.
UPS (Uninterruptible Power Supplies) units will provide power to all cameras in the event of a power failure, thereby mitigating concerns about turning off the camera.
In addition, if it is difficult not to install your camera on a metallic / conductive surface, add a wooden block in between.
Low or low bandwidth Wi Fi connection
Video loss or weak video signal among cameras and Wi Fi security systems can be caused by unstable network connections, weak WiFi connection, or low Internet bandwidth.
Here are the common reasons for network-induced video loss:
- Long distances between wireless security cameras and home routers.
- Too many obstacles between your camera and WiFi.
- Wi Fi signal interruption and interference.
- Insufficient bandwidth via PoE switch or NVR.
- The loose connection between the BNC connector and the security cameras or the DVR.
What are solar powered video surveillance cameras?
Solar CCTV cameras, or CCTV cameras with solar panels, use a solar panel for power and require no power or cables.
By using solar energy, you can make the most of natural resources to charge and operate solar-powered video surveillance camera systems, with no subscription or monthly fees.
Normally, a stand-alone wireless solar security camera system is sold in batches, including a solar panel and a solar video camera with rechargeable batteries.
Top 6 Benefits of Solar Powered CCTV Cameras
Solar video surveillance cameras allow flexible placement.
A CCTV camera powered by solar energy requires no cables or electrical network to operate. It can therefore be used in various surveillance applications, such as remote sites or geographically difficult environments.
Typical sites where you can install a solar-powered surveillance camera include, but are not limited to, your vacation homes, hangars, construction sites, vineyards, farms, barns, boats, warehouses, RVs, etc. .
Easy to install and move.
DIY solar-powered wireless CCTV cameras are quick to install in the locations of your choice because you don’t need bulky cables, which is a relatively beneficial security option.
Best of all, you can easily move your solar video cameras when a project is progressing or ending, such as construction sites or your new pipes under construction, and then take your solar IP cameras to a new site.
A low carbon footprint on the environment.
Powered by renewable sunlight, solar powered video surveillance cameras will not harm the environment from pollution such as waste and disposable batteries.
In addition, creating an infrastructure to support traditional surveillance systems can be disruptive. Solar powered surveillance cameras require no infrastructure and can help preserve areas such as wetlands.
Solar cameras provide day and night surveillance.
As explained above, wireless security IP cameras powered by solar energy can be powered by rechargeable batteries at night when sunlight is not available.
In addition, Wi Fi security cameras from some reputable brands are equipped with sensors capable of providing night vision in vibrant colors, which is a big improvement over other security cameras.
Easy to adapt.
Solar powered video surveillance cameras are also a flexible and scalable solution if you want to add 2 or 3 additional cameras later.
Thanks to the CCTV camera viewer, you can also watch live viewing of several solar IP cameras on your Smartphone simultaneously.
Solar powered security cameras have a long lifespan.
Most solar panel manufacturers offer a standard 25-year warranty, which means that the security camera solar panel can still produce as much as 80% of its power after 25 years and also requires little maintenance. .
Do security cameras work through glass?
It is common to install a security camera in front of the window that faces outside to monitor the front door / backyard or to install a security camera inside by looking through it. window.
Some people also claim that security cameras will not work through glass or a window. Who should we listen to? should a camera be installed in front of a window?
Or, to be exact, what potential problems you might encounter when placing cameras inside while looking through a window. ? Can an infrared camera see through glass or a window? Does motion detection work through glass or windows?
One of the common problems that you may encounter with an infrared security camera behind / through a glass window at night is glare, whether by infrared LEDs, ambient lights, or status lights.
Glare from windows or reflections from glass can cause images to bleach or videos to be washed out by overexposure of lights at night, making it difficult to distinguish details.
During the day, the cameras operate normally.
Another problem is related to motion detection and motion recording when a security camera is placed behind glass or a glass window looking through the glass. Sometimes motion detection does not work through the glass.
Do infrared security cameras see through a window?
Infrared security cameras tend to erase the image when placed behind glass or glass panels at night or in low light. In these scenarios, you will not be able to see things clearly.
What corrections should be made?
To avoid glare on a surveillance cameras in Chicago looking through a window, users can deactivate the IR lights as well as the status lights at night, which allows to limit the reflections of the IR security camera and to see through. glass.
Also, to reduce reflections on the window, place the camera lens as close to the glass as possible when placed behind glass.
Or by using a suction cup mount that adheres to the window that faces the outside, for example, this suction cup mount even comes with a magnetic screw mount that allows it to attach to outdoor cameras.
Installing motion-activated or automated external lighting or exterior street lighting helps to illuminate the front door or backyard, allowing security cameras to capture detail better.
Does motion detection work through glass or behind glass?
There are two main types of motion sensors used in security. One is a motion sensor that triggers alerts by measuring changes in pixels, which is based on a software algorithm, for example.
The other is the passive infrared motion sensor that triggers motion alarms by detecting body heat and infrared energy, called a PIR motion sensor.
Security cameras with a motion sensor that calculates pixel variations will still be able to detect motion and record through glass.
The PIR motion sensor security camera does not work reliably or sometimes does not work at all through windows or glass, as most glasses used in modern homes are insulated, thus limiting the heat passing through the glass. , which harms back to motion detection.
Advantages and disadvantages of cellular security cameras
No electronic device has any malfunction. The same goes for home security cameras. Cellular CCTV cameras are no exception.
Here are the pros and cons of cellular surveillance camera systems.
Benefits :
Flexible location
Since most cellular security cameras are powered by batteries and some of them are solar powered cellular security cameras, no power outlet is required.
The WiFi network is also not necessary for cellular surveillance video cameras.
So you can place 3G / 4G LTE / 5G security cameras wherever you want
Maximum security
Compared to security cameras that use the Internet to transfer data, security cameras that use cellular signals are much more secure and it is difficult for intruders to hack into a cellular security system.
But don’t get me wrong, there are also point-to-point (P2P) secure wireless camera systems.
Easy installation
Similar to wireless security cameras, 3G / 4G LTE / 5G cellular security cameras can be set up by yourself in minutes.
Simply power your indoor / outdoor cellular security cameras and insert a SIM card into the camera.
Once you’ve downloaded the seller’s custom app to your phone, you can easily access the wireless cellular security cameras to find out what’s going on.
Remote viewing from anywhere
Traditional wireless home surveillance systems without the Internet will not allow you to watch live video remotely.
As noted above, security cameras with cellular service can allow you to stream live video anywhere on your phone, even without a WiFi network or power source.
The inconvenient:
The price
The cost of Wi Fi and battery powered cellular security cameras is certainly one of your main concerns.
And here’s the reality you face: cellular security video cameras are relatively more expensive than other types of camera models.
Not only is the cellular camera alone expensive because of advanced technology, you also have to spend money on the data plan of the cellular surveillance cameras.
The scams
Look for Wi Fi and cell-powered security cameras on Amazon and you’ll find a variety of options there.
However, most cellular security systems for sale are from unknown brands.
What about their quality? that remains to be seen…
Camera battery life
With regard to battery-powered 3G / 4G / 5G security cameras, you may be concerned that they may soon lose their battery life.
It is best if the 3G / 4G / 5G cellular security cameras running on batteries can send you low battery notifications so you can stay informed about the battery consumption and replace / recharge the batteries in time.
Keep in mind: cell security systems powered by rechargeable batteries would save you frequent replacement costs and allow you to be serene at all times.
And it’s even better if your wireless cell security camera has a solar panel backup, from which home cell security systems can be powered continuously.
In any case, if you have the necessary budget, prefer this type of system.
