IR (Infra-Red) CCTV Security Dome Cameras: Application and Issues

Dome Camera too close to reflecting surface.
Mounting an IR dome camera underneath an eave without enough vertical clearance between the dome and the eave, may cause the IR LEDs to reflect off of the bottom of the eave and bounce back into the lens, ruining the shot. This same effect can be duplicated in a variety of mounting scenarios. Keep the angle of projection of the IR’s in mind when mounting your security camera. Bounce back from objects too close to the IR is extremely common.
Scratches on Dome Camera Outer Cover May be hard to detect.
Testing was done with an integrated IR CCTV Dome Camera to see how these very issues impacted images during day and night. The dome camera was tested with light and heavy fingerprints, dust, dirt, and also with slight scratches. To the eye, some of these issues were not noticeable unless carefully inspecting the camera and could easily go overlooked in the field. Even slight smudges, dust, or scratches had significant negative impact on image quality at night with IR on, reducing details and blurring portions of the FOV (Field of View), even if these issues were not present during the day, or visible on the dome camera cover itself. Very little force was required to scratch the polycarbonate dome.
Fingerprints on the inside or outside of Dome Cameras cover.
Again very hard to actually detect but will cause significant issues. Fingerprints can get on the inside of the dome camera cover during installation just as easily as the outside. Make sure the inside of the dome cover is clean before re-installing. After placement, the angle-of-view and focus is set, a final cleaning should be done before closing the cover.
Placement of Black O-Ring around lens is not correctly seated or off-center.
When reinstalling the dome camera cover, make sure the O-Ring that surrounds the actual lens is placed so that it keeps any IR from bleeding through. This will cause a glaring effect on the image. The ring should be snug against the dome cover all the way around.
Dust or Dirt, etc, on Dome Camera Cover.                                                            
This seems obvious but is very common.  Dirt builds up on the dome cover but is barely visible to the naked eye. The image will still be great in the daytime but as soon as the IR’s kick on you will see a plethora of issues. Be careful cleaning the cover as well.
Shooting IR Camera through glass is not optimal.
IR LED’s will bounce back when going through glass. IR Cameras that are observing an external (outside) area should be installed outside. Installing the camera indoors and shooting through a window will not work.
Use a Scratch Free cloth to clean your CCTV Dome Camera.
Cleaning your dome with a rough or dirty rag may do more harm than good. The poly-dome cover will scratch easily and should be cleaned gently with the appropriate material.
Wrong Camera Selection
In many areas, a problem can be solved by switching to a Bullet style Security camera. Some areas are not optimal to the profile of a Dome style Security Camera. Check with your Dealer or distributor for options. IR Dome Security Cameras are extremely popular due to ease of installation and rugged form but may not be the best choice for all CCTV Camera applications.

Factors to Consider When Shopping for the Best Samsung Security System

Keeping your home or commercial premises secure at all times is essential. Samsung has designed a variety of high-tech security systems meant to be used in both commercial and domestic applications. Before you go out and purchase a Samsung security system, it is important that you familiarize yourself with some important factors.

Read on below to find out some of the main considerations to keep in mind when shopping for a Samsung security system. 


When purchasing a Samsung security system, it is important for you to have an idea of the number of cameras it can support. Each security system comes with a given number of cameras; you can add more cameras where possible. However, it is worth noting that the number of channels supported on a DVR device limits the number of cameras that you can link to it. DVR security camera configurations come in four, eight, nine, sixteen and thirty-two channels. Since you cannot add more channels to a configuration, it is best for you to purchase a system that can support all the cameras you need, not only now but also in the foreseeable future.


Before buying any security system, it is important to think about how compatible it is with other technologies and accessories. It is recommended that you look for a system that is compatible with a variety of viewing and control devices including visual display units and smartphones. Furthermore, the system should support the use of accessories including cameras from different manufacturers. Note that the Samsung security system is designed is designed to be compatible with PTZ cameras; while viewing on a variety of mobile devices and computers is also supported.


The storage device in use is a vital part of a security camera system. Although storage space is not as expensive, it is important to ensure that you have all the space you need, at present, in the Samsung security system you choose. Furthermore, remember that the video compression technology used to store the video has an effect on how quick the storage space will be exhausted.

With the above factors in mind, you will have a better chance of choosing the most suitable Samsung security system for the intended application.

Surveillance Camera: An Essential for your Home’s Security

In many businesses, having a surveillance camera is believed to be one of the best ways to be protected from theft or vandalism. It also aids in the process of investigation, making it easier to find the perpetrators. Its applications, however, extend beyond commercial purposes. It can also be used in the surveillance of homes. Many homeowners, who are concerned about their security, consider the installation of these cameras as a way of having peace of mind.

Choosing the Best

Over the years, the surveillance camera became more popular because of their many and ever expanding amount of applications. With this, different models and systems have been introduced, each with the promise of being the best. However, you should not easily decide in haste. You should consider a variety of factors to decide which camera suits your needs.

One of the most important features would be night vision, allowing the surveillance camera to provide clear images even in poorly lit areas and at night. Weatherproof rating is also an important consideration, especially if the cameras will be installed outside the house.
Look for IP66 rating for cameras exposed to the elements. Having a motion detector is also a good thing. With the latter, you can save on precious storage space as the camera will capture only events when there are movements that are recorded. Video compression is also a consideration. Lastly, and perhaps most importantly, it is also necessary for the surveillance camera, or system using to employ that camera, to have a capability for remote access. This means that through your smartphone, tablet, or computer, you must be able to monitor what is happening real-time from the area where it is installed.
This is its most important feature to ensure security at home.

Making the Most from your Surveillance Camera

To be able to make it as effective as possible in providing the surveillance that you need, one of the most important things is to make sure that they are positioned in strategic locations within the home. In this case, one of the best locations would be the front door, which is believed by to be accessed by 34% of burglars. The backdoor, off-street windows, and garage will also be critical places. If you have a baby, having a surveillance camera in the nursery is also essential, especially if there is a nanny and if you are always away from home. If the house is fenced and has a gate, the latter is also an excellent location. Positioning the Surveillance cameras in clearly visible locations is also effective in preventing many incidents in the first place.
