How to Maximize Range of Your Wireless Security Camera?

How to Maximize Range of Your Wireless Security Camera?

Wireless security cameras are the ideal option for businesses and homes, especially for high-up and long-distance installation. To help maximize the range of your wireless security camera, here are some helpful tips for increasing signal strength. Ways to improve connectivity and range can apply to wifi cameras or cellular cameras.

Optimize Your Wireless Signal.

The quality of the video you receive will ultimately be determined by the strength of the wireless signal between the camera and the receiver. When the signal strength is high, the video you receive will be smoother with a higher video frame rate; however, when the signal strength is low, the video you receive will have a lower video frame rate.

How To Maximize Signal Strength?

You can easily maximize your video footage by extending your wireless camera range when you understand the factors that both strengthen and reduce wireless signal.

  • A Clear Line-of-Sight: Endeavour to limit the number of obstructions situated between the camera and the receiver. A strong signal will be received if there is a clear line-of-sight.
  • Competing Signals: Try to avoid placing receivers or cameras near other wireless signals and leave the maximum amount of space between wireless receivers.
  • Positioning Antennas: A high-gain antenna will aim the wireless signal in a single direction, creating a narrow, more focused signal that targets the receiver.

Barriers That Negatively Affect Wireless Signal.

The signal range will vary depending on the objects or type of building materials the wireless signal has to pass through, as it moves from one point to another. The weather, as well as various types of building materials, will produce different signal reactions, such as:

  • Refraction: As the signal travels through an object it changes direction.
  • Reflection: The signal reflects back off an object, like a ray of light.
  • Diffraction: As the signal passes around an object it changes direction.
  • Scattering: The signal disperses into multiple new signals.
  • Attenuation: This refers to the decline in signal strength during transmission. The loss will be increased as the signal passes through objects, or by long distances.

Construction Materials and Signal Reduction.

As detailed at preceding link called "attenuation", certain construction materials like windows, drywall, and cubicle walls, typically don't degrade wireless signal strength very much because they are light and thin. These materials let the wireless signal pass through with minimal impediment. However, there are other building materials that significantly reduce signal, such as:

  • Brick: Signal reduction of 30-50%.
  • Wood: Signal reduction of 10-30%.
  • Metal: Signal reduction of 70-90%.
  • Concrete: Signal reduction of 50-70%.

Above figures show just how dramatically construction materials can reduce the strength of wireless signals.

How To Extend Wireless Signal Range.

Extension Cables for Analog Receivers: Use a Siamese BNC extension cord to mount the wireless receiver further away from the DVR (maximum 60 feet). Now you have the ability to optimize signal by placing the receiver in a better position. As an example: If the receiver is extended to the same room as the camera, you will avoid a lot of signal reduction.

Wireless Range Extender Antennas: Use an Omni-Directional antenna to extend the range of more than one wireless camera; or direct a wireless signal onto one particular camera using a 2.4 GHz Direction Wireless Panel Antenna. Both of these types of extenders can be combined by directly connecting the directional wireless panel antenna to the camera.

Weatherproof Receivers: Our wifi network security camera, and cell network security camera come with weatherproof receivers. You will achieve a better line-of-sight by using a Siamese BNC extension cord to install the receiver outdoors, in addition to significantly improving signal strength to your outdoor wireless camera.

  • Talk about your relevant blogs! The recent Amazon Sidewalk debacle shows how much trouble people are having getting reliable signals for their wi-fi devices like cameras and other wireless security items. Do you really want to trust your own wi-fi to a mesh network that might be hacked? Not me. I opted out as soon as I heard about this and if my wi-fi security doesn’t work adequately, I’ll purchase a wi-fi booster.

  • I think the cost of wireless cameras has come down so much that more people are installing them. There are so many good reasons for getting them, but like anything, price is key. When I look at the different things that can affect the signals, I come back to the idea of getting a wi-fi booster just to make sure they’re working 100%.

  • I was at a certain online vendor’s site and I started reading the reviews for wireless camera systems. One of the frequent complaints was a lag time with the cameras. While I’m not an expert, this article suggests that a weak wi-fi signal (weak either to begin with or weakened due to obstacles like the ones mentioned here) is the cause. A wi-fi signal booster sounds like a good tool to pair with any wireless security camera system.

  • This was the information I needed. I’m getting a four-camera set for home security and I was wondering what problems I might have with a wireless setup. I’ve seen elsewhere that wi-fi boosters can be a big help, but I’m going to try and use these guidelines before I get one.
