How Do Wireless Security Cameras Work?

If you want to ramp up the security in your home, you should review the benefits of adding a home security camera. This modern security marvel enables you to capture a burglar or thief and provide solid proof to the police.

Police also like it when homeowners use home security cameras as they can make arrests that can be prosecuted successfully. When you can identify a perpetrator on film, it makes the use of wireless security cameras all that more important.

If you would like to know how wireless security cameras work and how they can secure your premises, you must first define this type of surveillance system. However, before you make the distinction, you need to learn more about home security cameras and other surveillance systems.

A Catchword and Buzzword

If you are similar to most people, technology is one buzzword that seems to be a catch-all term that can cause confusion when you are trying to purchase a surveillance camera or this type of upgrade. The surveillance industry is one small part of the technology sector. When you install a home security camera, you feel as though that you are maintaining an “eye” on your surroundings. However, this “eye” is made of glass and never blinks. It maintains its focus nonetheless.

By learning more about camera surveillance, you can appreciate the functionality and workings of wireless security cameras. Before you chose a wireless security upgrade or camera surveillance for your home or business, you need to identify your security requirements along these lines.

What You Need to Ask

For instance, if you are considering wireless security cameras for your business, ask the following questions:

  • Will I need to monitor employees or my cash registers?
  • Do I want the camera to track visitor comings and goings?
  • Do you wish to increase the activity of your employees?
  • Will you need surveillance to prevent vandalism on your lot?

Maybe you wish to buy a home security camera. If so, you probably are considering one to prevent burglary or theft or to keep your family safe from prowlers or the nefarious activities of similar criminals. When you regard the use of security cameras for homes and businesses, they can be used for a large number of applications. Therefore, you need to carefully review the reasons why you want to buy a surveillance system.

What is nice about wireless security cameras is that they can be used in a small business setting as well as a large corporation. They can also be included in just about any size residence. You can incorporate the cameras as easily into a high-rise building as you can in your little bungalow or cottage. You just need to think about how many you want to install and their placement or placements.

Security cameras that are wireless can be used indoors or outdoors. However, some of the smaller models are often used inside a house. Whilst many outdoor cameras can be placed within a home, no indoor camera should ever be placed outside. When an indoor camera is placed outside, it can get damaged from inclement weather conditions as well as grime, the sun, or dust.

As noted, you can always use an outdoor camera inside a house or business as it is designed to stand up well to various environments. Some of the places that use this type of application include schools or prisons. In these instances, a heavy downpour may slip inside an open gate.

If you do choose to add a wireless camera to your institution, home, or office, you may be surprised that this type of technology is not truly wireless, at least not in the sense of being connected with an Ethernet cable. This type of cable connects the camera to a video recorder. When a wireless camera is used, the recorded images are transmitted without the cable or through the atmosphere.

Why People Like Wireless

Most people who add a wireless camera for surveillance do so to cut down on the number of wires running through a home or office space. This type of operation is also a great addition in a place that wants to conceal its security camera. Some people like wireless camera upgrades because they reduce the confusion associated with a more complicated system.

Therefore, a wireless camera can be placed in one of various unique locations. Because they do not use power cables, the data is sent wirelessly to a receiver and uploaded on a screen or monitor. The power that fuels the system is normally supported by lithium batteries. By taking this approach, users can cut down on the installation time. If the codes in your building prevent you from using wires, this is a good system to install.

You may wonder how long the power lasts for this type of camera. Usually the lithium-ion cells that are used to power the camera provide consistent power that naturally fades over time. Nevertheless, it is easy to replace the batteries. Systems may also be powered by a single cable.

Broadcast Ranges

Wireless security systems transmit data in broadcast ranges that go from 2.4 GHz and 5.8GHz. Again, transmitters send the data over wireless signals that receivers pick up. A wireless camera covers about 600 feet (183 meters) to as much as 2000 feet (610 meters), depending on the rate of GHz. If you place a camera in a house, the distance can become limited because of walls or obstructions.

With that being said, you can easily extend the range on a wireless security upgrade. You can use repeaters for this purpose. However, if you use several repeaters, you may also reduce the quality of your video.

If you are using the system to catch a thief, extending the range may hamper your efforts in this respect. Also, you should place the camera close to the area that you want to be covered. Expanding the distance can also hamper the signal.

Preventing Problems with Transmissions

Besides distance, other things can also get in the way of the signal transmission. For example, if your office features metal walls, they can obstruct the entire signal or a good part of it. Otherwise, a signal will easily transmit through drywall or glass. It will also break through wood, masonry, or concrete. If the camera is located outdoors, sometimes certain trees will hamper a signal.

Also, you have to consider competing types of signals or transmissions that will get in the way of your wireless signal. Make sure that you place the camera in a spot that is not adjacent or near items such as wireless routers or wireless phones. You should also keep cameras away from obstructions that lead to reflections, refraction, scattering, attenuation, or diffraction.

That all-important signal should be strong as a weakened signal impacts the frame rate. This means that you should choose a wireless camera system with a strong, unyielding signal. If your camera cannot transmit data or images clearly, all you will end up getting is scrambled video playback. While repeaters can be used to impart a better transmission, they can, as noted, still affect the video’s quality.

How Is Your Internet Speed?

If signals clash during transmission, it can also affect the speed. That is why the placement of your security camera is crucial. Make sure that the signal strength ranges between 2.4 GHz and 5.8 GHz to prevent problems with signal strength.

You also need to be aware that a wireless camera can be hacked. Just don’t leave the security used for the camera at the default settings. This can be a big mistake. Instead, change the ports that the camera uses. Change the camera’s password and address name as well. The security camera you use should stay hidden behind your Internet use and not be positioned in the open.

The cameras save footage in two places. Usually, the footage is saved on the camera with an SD memory card or via a coordinated video recorder. Experts recommend buying a networked video recorder for any type of security monitoring and surveillance system.

The SD Memory Card

While an SD memory card can be convenient to use, you also have to access the card in order to retrieve data. This can turn out to be a hassle after a while. Also, you may want to include a hard drive for recording your footage. Although a small wireless camera can hold a good deal of footage, a hard drive can assist you in recording a whole week of footage.

If you are trying to decide between wireless and wired, you will find that wired security cameras are cheaper than their wireless counterparts. Experts suggest getting wireless cameras if you feel that a wired system may cause tripping hazards or you wish to conceal the camera more easily in your office or home.

Scaring Off Criminals

After all, you do not want to alert a perpetrator about your video surveillance in either your home or office. Criminals will feel more inclined to carry out their crimes if they feel that no one is watching. However, if you simply want to scare a burglar or thief away, you may be better off choosing a system that is easier to spot or see.

Wireless cameras are very lightweight versions of their ancestors, the old analog surveillance cameras. These old-time cameras are what people often think about when they are thinking of a security camera. Analog surveillance cameras are bulky in appearance and feature a large volume of wiring that seems to fly helter-skelter in the air.

These old cameras use composite wires instead of Ethernet cables that networked or wired systems employ. While these cameras are really old versions of security systems nowadays, they can support your efforts, if inconveniently.

IP Cameras

You are going one step up when you employ a networked surveillance or IP camera for surveilling your property. These cameras are supported by Ethernet cables. As long as you rely on one cable, you can reduce any tripping hazards or liability.

This type of camera sends surveillance images to a video recorder or a web browser. You can access these cameras through your phone app or apps that have been installed on tablets or laptops. These cameras, you might say, work the same way as a wireless camera but transmit images by cable instead of wirelessly. The still include wires and work without lithium-ion batteries.

Selecting Wireless

When selecting a wireless camera, you will need to determine where you want to place the camera so you can maintain signal strength. You also want to make sure that your video recording is high-definition and easy to see. Some people find that it is easier to include more than one wireless camera on a property so they can fully secure premises.

Plus, it does not do you much good to add a camera in the front of your home and let burglar access the back of the home to steal your belongings or vandalize your property.

Just make sure that you cover all the ports of entry so you will feel safer and more secure. Also, check out how you want to connect what you record. Most wireless applications allow you to see recorded data via a monitor on your computer.

You can regard this type of camera as a step up from an IP camera or networked connection. Because it transmits data wirelessly, it is a convenient solution and upgrade.

Some of the Determinants

Now that you know how a wireless security camera works, you need to find out what camera will be right for your home or business. You need to think about the following:

  • The area you want to cover
  • The night vision operation on the camera
  • Whether you wish to add a zoom lens
  • The placement of the camera
  • Whether you want to hide the camera
  • What makes the camera a perfect surveillance upgrade

As you can see, you have a good deal to consider when you are choosing a wireless camera. A fully functioning surveillance system should be based on the number of cameras you need, the hard drive storage you may want to include, and whether you plan to add a power cable or operate solely by a battery.

You also need to figure out what recording software you may need or any additional hardware that you may want to include. You will need at least one video monitor to review the footage.

Next, you will need to consider your budget. What type of lighting conditions prevail in the area that you wish to secure and watch? Also, do you wish to buy a home security camera that is designed for indoor use, for outdoor use, or for both locations? Do you already have any security cameras set up at your site? If so, are they IP cameras or analog designs?

Signal Transmissions

Next, you will need to consider installation. Many wireless cameras are easy to set up. Most of the cameras come with instructions for setup and use and often are easy to install.

Make sure that you choose a brand that is very easy to install or, at least, is represented by a company that will help guide you through the whole installation process. Just remember if you are mounting the camera to take special care if you have to drill into concrete or wood.

This can be tricky to do if you are not careful. You also want to make sure that the camera cannot be easily seen by a criminal or anyone entering your premises. However, if you do want the camera seen to drive off the perpetrators, make sure that you include a sign that they are being recorded or that they are entering a restricted area.

An Easy Installation

One thing that is nice about a wireless home security camera is that you do not have to inspect your electrical wiring or plumbing before making the installation. In most cases, you can bypass this little detail. When you finally install the camera, recheck the angles and views of your camera after installation. Make sure that you are focusing the camera on the areas that you want to have monitored and surveilled.

You can learn a lot about security when you install a premium wireless camera. Why should you hassle with a lot of wires that can disturb your equilibrium? Review the benefits of installing a wireless system for your office or home today. The more you know about how this camera transmits signals and operates, the easier it will be to place it in key locations on your property.

Ask yourself what you want to achieve with a home security camera upgrade. If you already have video surveillance on your property, you probably want a more streamlined and smarter camera to do the work. By choosing a wireless system, you will find that you will meet your security and surveillance objectives.
