We all know that the main purpose behind installing a security camera is for security purposes, thus when something happens it can easily provided us with the evidence we need. Now in terms of security camera, features like sharpness and clarity should be paid more attention , those are the main factors that could help a lot in making your footage more clearer. But there’s some factors that will still be affecting the sharpness and clarity of the security camera, in the following we will provide you with some of the main factors that is affecting the sharpness and clarity of the security camera. Now let’s get started.
Resolution
Like most of the security camera, each camera’s pixel density which also can be described as the image resolution, the higher pixel density you chose, the more facial details you get. There are various resolution available in the market, for clear image, you are supposed to choose at least 2MP.
Lens
It might sound surprising to you that even lens can be the factor that is affecting the sharpness and clarity of the camera. And as a matter of fact it is, lens falls into three different categories which are fixed lens, vari-focal lens and zoom lens, each will determine the quality of the security camera in one way or another. So if you are trying to change the lens of the security camera, then you should choose the right one according to your own standards. Choosing the wrong one will lead to a blurry footage and a bad angle of the footage.
Frame rate
As for the frame rate, the definition of it is it defines the number of frame or images that a security capture per second. Now sometimes the frame rate might be hard to watch due to the fact the rate is below 15 frames per second and the quality is really bad. So while you are trying to choose a security camera, it’s crucial for you to keep an eye for numbers likes this (15 frames per second) when measuring the quality of the security.
Image sensor
In a security camera system, the image sensor is also one of the main reasons that affect the quality of the footage, so basically an image sensor is a camera hardware component that captures light in a camera, converting it into electronic image, and the security cameras image sensors often dictate the whole image quality. Image sensors have two types in the market, the CCD and the CMOS image sensors. The difference between the two is that, CCD is an old tech and the CMOS is the new tech, but the CCD is considered to be much more superior in its technical features.
WDR/HDR
We don’t normally see these or heard of these kinds of features in a security camera systems before, so it might be new to most of us. Both the wide dynamic range (DWR) and the high dynamic range (HDR) are different in their technical capabilities, they both mainly serves the purpose of increasing the cameras range and solve the dilemma of balancing out the lighting to achieve the best possible quality of both images and videos. But the WDR is more preferred in most cases.
Video compression
A video that is capture by the security camera will go on the process of compressing by itself, or the recorder will make the best use of the storage space. But sometimes in those cases the quality of the image can be lost. The standard option in security camera system is the H.264, most of the manufactures use this standard with a MPEG-4 video compression.
Night vision
Now you cannot sell a security camera without a night vision as a feature, it’s basically like going out without wearing your shoes. Most night vision security camera has the capabilities that use infrared LEDs, that make them see clearly even in pitch black environment. It’s common as you view the night footage, the images will broadcast it in black and white. Just to be clear, not all night vision systems contains the same capabilities to see through pitch black, some night vision cameras can only see in low-light condition, so it’s better to get some facts fight instead of thinking the wrong way.
Monitor
If you camera system requires live stream and display on monitors, such as TV, computer or others, the image quality of the monitor affects the sharpness of video image quality at some extent. That means although your camera supports 2MP resolution but the monitor only support 720p, it is impossible for you to get the same image quality. So if you require extremely high quality image, you need to equip with a high resolution monitor too.
WiFi signal
As to WiFi camera, it is crucial to make sure the WiFi signal is strong enough around the camera mounting point. Because only the WiFi signal is stable and good quality, you are opt to get high definition video image from the WiFi camera. Therefore, you’d better test the WiFi signal before you purchase the camera or find some ways to extend or boost up the WiFi signal.
Extension cable length
Extension cable is used when the power outlet is a little bit far away from the WiFi camera, the power consumes in the process of transmission as part of power turns to energy, thus if the power cable length is too long, it results in sharply power drop problem then the camera operation is hard to keep in stable status, not to mention receiving clear image quality.
Now here are some of the tips that could help you get a clearer image quality, it’s simple and affective.
- Make sure to keep the lens clean before or after using it.
- Always make sure the camera has been set in the correct resolution.
- When the environment is dark, make sure to provide light around the camera.
- Avoiding too bright location and adjust the lens while installing the security camera.
- One of the crucial tip is security angle ,the optimal installation angel should be less than 30 degree from the ceiling, this would help you get optimal view angle to capture useful detail.
- Last but not least, make sure to choose a high performance camera. After know what factor may affect the clarity of security cameras, it’s time to own your suitable cameras now. Various options for you to consider in here.
