The focal length is measured in millimeters and can be either fixed or variable. The focal length needs to be small to get a wide field view for the security camera. Large focal length allows a narrow field of view for camera surveillance. For a rough estimate, if you want the camera to see 40 feet then you need a security camera of 4.0 fixed lens.

If there are concrete floors, bricks, or large outdoor trees between the monitoring site and the camera then this weakness the strength of the signal. This greatly affects how far the camera can see.

The IR distance of the wireless security camera can be found out when you read the specifications of the product.

Conclusion

The line of sight of the CCTV cameras is important. When you know how far the security camera covers then it lets you set up the home surveillance system more efficiently. It does not leave any blind spots. The wireless security cameras function the best when they have a clear line of sight between the receiver and the camera. The outdoors cameras mostly have a range between 250 to 400 feet. The indoor cameras usually come with a range of 100 to 150 feet. Glass windows, cubical walls, and dry walls in most cases will not lessen the strength of the wireless security cameras. However, concrete floors, bricks, and walls decrease its strength. Trees in the range also affect the strength of the camera.

The signal range also gets impacted in case there are some competing signals that use the same frequency as the wireless security camera. Like for example, if there are cordless phones used at home then its signal can affect the strength of the wireless security camera. In such cases, you will see that the image looks froze.
