How Far Can a Security Camera See?
It is always crucial to know how far a security camera can see that helps install cameras in the right place. Besides that, It is essential to make sure that the camera can see and record at the required distance.
Basically, how far a security camera can see relies on multiple factors such as field of view, resolution, distance, and more. But, in general, a security camera can detect objects in a range between 0 and 70 based on its sensor, resolution, and lens.
On the contrary, some surveillance cameras come with high-resolution PTZs that can see further away, ranging between 0 and 700 feet.
However, in this article, we have shown how far a security camera can see with proper explanation and discussed the influence factors regarding that.
How Far Can My Security Camera See?
To ensure the best protection of your property and avoid potential blind spots, it is elementary to know the distance and the clarity that a surveillance camera can provide. A security camera footage needs to be clear enough to identify any intruder or detect license plates or car features.
Keeping these facts in mind, you have to calculate your location and sort out the distance between the mountain point and the prominent spot under surveillance. After that, purchase cameras depending on these ranges.
In addition, it should also be determined whether you’ll just capture the general area or you’ll need to identify faces, entrances, license places, etc. Basically, you’ll need normal regular cameras, but in some cases, you need special models like security camera with optical zoom to have the best view from the far away.
There are a number of factors and interfaces that determine the range of security cameras. Some cameras can capture clear footage far from a narrow-angle. On the contrary, others can see at a wide angle but closely.
However, you need to perceive all these factors and go for the cameras that will fulfill your requirements. In the section below, we have demonstrated all these factors on which how far a security camera sees depends. So, let’s check them out.
How Far Can a Security Camera See: The Influence Factors
We have mentioned very earlier in the article that, in general, a surveillance camera can identify objects in a range between 0 and 70 depending on its sensor, resolution, and lens.
On the other hand, some security cameras come with high-resolution PTZs that can see further away, ranging between 0 and 700 feet. Even then, some considerations can influence the range of view of a security camera that we have demonstrated here.
1. Focal Length
Focal length is the distance between the center of the lens and its focus, which is crucial considering how far a security camera can see. It is calculated in mm and can be graded into fixed focal length. If the focal length is small, your security camera can see a wide field of view. On the contrary, a larger focal length ensures a narrow field of view of your security camera.
According to the expert, if you would like to get a view of 40 feet from your security camera, a 4.0 fixed lens security is adequate to accomplish the trick. You can go for a PTZ security camera or a zoom security camera if the viewing area is above 40 feet from the location where the camera is placed.
It doesn’t make any sense if your camera can’t provide details of the detected objects. That’s why it is essential to focus on how far a security camera can see celery instead of asking how far a security camera can see, especially at night. That’s where the resolution of a security camera plays a significant role. You can install the 4 MP, 5 MP, and even 4K security camera system to have the best view with vivid details.
Another crucial factor that can also affect how far a security camera can see. Now a question may come to your mind, how? Well, the signal strength of your security camera can be weakened due to bricks, concrete floors, large outdoor trees between the camera, and even walls. Consequently, the view of security cameras becomes influenced.
4. Camera Quality
You can’t deny the quality of a security camera if you are determined to have the best view from far away. The viewing range of all security cameras is not the same, even if they are tagged with the same field of view. That’s why I always go for the top security camera brands with a large customer base that will confer reliable services to the customers.
Some cameras from renowned brands come with LEDs, 3D-DNR functions, and infrared technology that can see up to 33 feet in a dark environment. There are infrared security cameras like Reolink RLC-140 that can see up to 100 feet at night. Some PTZ cameras, such as Reolink RLC-423, can even catch up to 190 feet in the darkness.
How To Monitor Places At A Far distance?
If you would like to monitor places at a far distance, here is the guideline.
- Get a security camera with a varifocal lens that can provide you with a wide field of view.
- Don’t forget to use a high-resolution security camera to accelerate its ability to confer usable images and videos from a distance. For example, 4MP, and 5MP ones.
- Use PTZ with a powerful zoom.
- Purchase a security camera from well-known brands to avoid unnecessary problems in the future.
- Make sure the security camera you are going to purchase is able to see far enough with clear details at night.
- Go for professional security cameras with high resolutions.
You have to perceive the range of a security camera if you are planning to purchase one. We have provided details of a very few important things that you must know about. These will aid you in making a decision and thus confirming you that you made the best choice.
Taking into consideration these factors that we have discussed, you can simply decide what type of security camera you have to purchase. However, it is suggested to pick one from the well-known brands with high configuration.
