Wired vs. Wireless Cameras

Written By:

One of the most common questions that I get asked is about wireless camera systems. Everyone wants to have wireless cameras.  I guess that Hollywood has done a lot to make people think that a completely wireless camera system is a good viable option.  There are several advantages and disadvantages to both wired and wireless cameras.  When it comes to my personal security, I will always choose the hardwired system over a wireless system any day of the week.

A wireless camera is a camera in which the video is transmitted over the air to a receiver which captures and records the video.  A wired camera is a camera that transmits the video over a hardwired connection to a receiver. The camera generally not only transmits the video over the cable, but with the correct cable can get it’s power source that way as well.

Pros of Wireless Cameras

There are some pros to having a wireless camera system. The biggest pro would be the fact that installation is generally easier.  When you do not have to worry about climbing through attics or fishing wires through ceiling and walls, the job just got easier.  Typically all you need to worry about when installing a wireless surveillance system with regards to the camera is having a power source in a relatively close proximity to the camera.  Once that is done, all you need to do is mount the cameras and set up your recording device.  This sounds great on the surface, but in reality it’s not that easy.

Cons of Wireless Cameras

With wireless cameras there are a multitude of downfalls.  One of the biggest downfalls that I see are picture quality.  With almost every wireless camera that I have seen on the market, the resolution quality is generally less than 702×480.  When it comes to quality surveillance cameras you want a higher resolution to gather as much detail of the image as possible.  I feel that the reason a lower resolution image is used is so that it can transmit the video footage in more frames per second with less latency in the video.  Another downfall with wireless is that they generally are in the 2.4ghz spectrum.  If you look around most places, that spectrum is inundated with use.  Generally speaking there are 14 channels available in this range.  Inside of this range you have everything from wireless B and G networks, some parts of wireless N networks, a new wireless network AD which is in it’s draft phase will still use some of this range, microwave ovens, baby monitors, digital cordless telephones, car alarms, and bluetooth adapters.

This range of frequency is very crowded and the overlapping of channels with their frequency ranges is a recipe for disaster in a security system.  Adding in yet more devices that are on the same bandwidth, you are asking for interference.  With interference you will get lost signal, dropped signals, and lost video.  I don’t know about you, but I want to know that my CCTV system is always going to record when I needed it to.  Lets say you want to put a camera in a spot without a close power outlet, you have one of a few options.  You can either try and find a battery powered camera, good luck finding anything worth it, have an outlet wired closer to the camera location, or move your camera location closer to an outlet.  These all seem to me that they are more trouble than they are worth.  When I am installing a camera, I want to be able to put it where I am going to get the best possible shot, not where power is going to dictate.  If you find good locations with close power, you better hope that there is no major obstructions in the way, like too many concrete walls, or any of the other items that may interfere with the signal.  If you want a wireless Pan Tilt Zoom camera, they are out there, but if the video signal doesn’t come in do you think the control of the camera is going to be any better.

Pros of Wired Cameras

With every type of method, there are pros and cons.  One of the pros of having your cameras hardwired is that you can count on the picture coming into your recorder.  The power and video can be ran on 1 cable, so everything can be centrally located.  No interference from telephones, bluetooth, wireless networks, microwave ovens, baby monitors, or car alarms.  A wider selection of camera styles are available for use.  You can have a Pan Tilt Zoom camera, to allow you to have one camera to look all around.  You can add audio to your security system without major hassles.  No need for the cameras to be mounted close to a power source, the cable will carry it wherever you need, within reason.  If you use a power distribution box up to 16 of your cameras can be powered with one unit, eliminating multiple power supplies.  There are several different types of wire that can be used to wire your cameras.  You can do simple plug and play, separate RG59 or RG6 and 18/2, Siamese, or Cat 5 cable to wire your cameras.  Wired cameras are harder for someone to disrupt the service of the camera system, by not allowing frequency jamming devices to interrupt you video signal.

Cons of Wired Cameras

With every wiring job comes some complications.  When you are wiring a camera system it is no different.  You can run into studs, concrete block, and other obstacles that can not be seen with drywall up.  You typically have to climb around in an attic and deal with insulation.  You will have to fish wires down walls and around other objects in your path.  If you lay the cable on a high powered line you will get interference on the picture of that camera.  If you choose to use any cable other than plug and play cables, you will have to terminate the ends for it to work properly.


There are some advantages and disadvantages for both types of camera styles.  I personally feel that if a wireless option is what you are looking for, you should do an IP solution with access points and an omni directional antenna.  With this type of setup you are getting the highest rate of resolution for security cameras and you are dealing with network based protocol with better transmission than standard 2.4ghz wireless receivers and transceivers.  With this type of a setup you will still need a power supply close to the camera location for the access point and the camera.  Another cool thing you can do is if you need a camera at a location that is too far to run a cable, and there is line of sight, there are access point/bridges that can travel for miles.  This is very useful for gates and remote camera locations but you will still need a power source.  This will save you from trenching a cable all the way to the camera location.

There are some downfalls to this type of setup, you are sending high quality images over the air and most units can only handle a portion of the data at once.  Most access points are limited to 150 mbps (Megabytes Per Second) up and down. When you are talking about a high resolution image you may be able to get approximately eight 2MP cameras before running into network issues.  If you want to get around this you may want to use multiple access points/bridges to communicate with each other and then you will have 150 mbps on each set of units instead of being limited to the one omni directional access point.  By doing this type of a setup you will be limited to the switch that they go into.

You can probably tell by now my which way I lean when it comes to wired vs wireless.  I am a firm believer that if you are going to spend the time and money to do something, you should do it right the first time and not have to do it over again.  I do not want to have to worry about not getting the images from my camera to my DVR, take the trouble to have to have electrical reran just to fit a camera location, or settle for subpar equipment just to make my job easier.  Wireless cameras are still in the infancy and I feel are years away if ever from being perfected.

Nano Station M5 PTP

Many Installers are requesting methods to connect their Security Systems. From running cable raceways in commercial buildings to installing conduit above or below ground in residential installations, running wired connections can take a lot of time – which equals more money to spend in labor. This article can serve as a guide on how to maximize the use of our Nano Station Loco M5. In this article we will be going to be utilizing an IP Megapixel system.

Example: IP camera System

Items Needed:

Before installing any hardware we first need to configure the Nanos. Lets start by Configuring the Nano that will act as an Access Point. This is the one that will be located at the Main Network.

Nano (Access Point)

Navigate to on your web browser.

Match your Gateway as well as the DNS server in this example we left this out as many networks are different.

5-STNavigate to the Ubiquity tab

Make sure to match these settings and hit apply .


Once you have completed both Nanos you can install them making sure that they both have line of sight between the devices, some minor adjustments can be done to ensure a good connection.

The Nano’s will lock onto the network by themselves or you can click on the SELECT button this will open up a tab that will display any Access Points in the area select the correct one and lock onto it.


If you wish to use the same settings as this tutorial you can download the configuration files here Configuration files- Nano M5. Download them onto your computer’s Desktop

There is a READ ME File which has the Configuration information that was changed on the two Nano Station locos

Once you have completed setting up your Point to Point Bridge we can focus on the location.

Once you have Downloaded the zip file go ahead and unzip it with your favorite extracting software like Zipeg  (Macintosh) or Winrar (Windows) Linux (Archive Manager)

Troubleshooting: How To Reset your Nano Station M5


In this illustration you can see that the Nano (Access Point) is in line of sight with the Nano (Station) that has an IP camera connected to it.



The Connections are simple

Site Side

  1. Connect the camera that you need to add into your Main network onto its own PoE Switch “POE Port”
  2. Attach the “LAN” Cable on the single port PoE switch to the “LAN” on the PoE switch from the Nano (Site)
  3. Attach the “PoE” Cable to the Nano Station “LAN” port.

Main Side

  1. Connect the Nano Station to its PoE switch  (“LAN” to “PoE”)
  2. Attach an Ethernet cable from your Router LAN port to the “LAN” port located on the Nano stations PoE switch.

*NVR connections are simple simply attach your NVR to the Router  by attaching a cable in between the LAN port on the NVR to the LAN port of your router.

Mounting Options:

The Nanos come already designed to be attached to a pole, there is a supplied Nylon Zip Ties.

The above illustration shows a nano installed using a tilt bracket .

This bracket is used to better position the Nano so that the bridge can be successful as both nanao’s need to be in line of sight.


Troubleshooting Tips:

If you have successfully connected all of the devices and you cannot seem to ping your camera on any device on the Station side, make sure that the WDS is enabled in both the AP and Station.

If signal is poor you can use the AirView Application to check your signals. If you are not that tech savvy you can use the Signal bars behind the units or simply log in to both and tweak your nano’s position.

Once you have completed mounting your camera and Nano stations as well as configuring your Nano’s, your system should be up and running. If you need to learn how to setup your DVR, see setup up your NVR

Also, to view your cameras outside your network, some port forwarding is needed. Since this is something that manufactures manage differently here is a link where you can search your Router’s make and model and find the correct way to complete this task. Ports that need to be opened are 37777,37778 and HTTP ports
