Wireless Cameras – what you can REALLY expect!

by Jennifer Spears
So you’ve decided that you need cameras. And wireless is going to fix every problem you have with running cables, getting power to the cameras, and it’s going to be snap to install them…
Let me go ahead and get my fairy wand out for you! Because that’s the only thing that will get all of that accomplished.
Wired and wireless cameras each have their strengths and weaknesses, but here I’m going to discuss wireless and specifically the limitations you have to make sure and meet so that the equipment works for you, and not the other way around.
So here are the limitations of commercial grade high range wireless, which is all we make here at Rugged CCTV.
The camera/transmitter has to have 110V power right next to it. You can add solar panels to it, and batteries if you want to, but none of the GOOD quality units are going to run on AAs.
Transmission distance has to be more than 600′ and less than 1500′ for the long range wireless. 600’ and 3 miles for the extreme range PTZ units.
The camera/transmitter has to be line of sight back to the receiving antenna or you will not get a picture. Anything in between (trees/buildings/water, etc) will be like putting a steel wall directly in line of your video. This is much worse in adverse weather conditions because the water/snow/ice clings to leaves of trees. So if you’re standing at your house, and you can’t see the barn you want to put a camera on – then wireless isn’t going to be any better than no camera at all.
The cameras will transmit back to a central location where the receiver will be located so all cameras need to be in line of sight of that box.
You can have a maximum of 4 cameras total on a single property. This does NOT mean 4 cameras at 2.4GHz, and 4 more at 5.8GHz. This is one frequency and 4 total. No mixing and matching because the signal will bleed over and you will never get clean video. There are some companies out there that claim they can do more, and it will only cost you a kidney to be able to afford it.
We make them in 2.4GHz and 5.8GHz and you would just need to choose whichever frequency the other equipment you are running ISN’T using.  Things to think about are wireless internet, walkie talkies, etc.
Huge power lines / power transformers running over your property can absolutely effect the video quality over wireless transmission as well, so this is just an added something to think about before purchasing.
Now remember there are lots of different companies out there that make wireless equipment. Some are useful up to 150’ only, some can be used indoor only, others 3 miles only. Just make sure you ask all of the right questions before buying equipment. Most of the wireless products available today are special build only and ineligible for return for credit. They will still carry a warranty for defects, but if you hang the camera and have two office buildings in between the cameras and the receiver and then want to return everything – not even my fairy wand will get you your money back.
Our wireless equipment ranges in cost from $449 for a single camera and receiver set up to $799 plus the cost of a PTZ camera which normally start at around $800. So wireless cameras are going to be more expensive than hard wired because of the need for transmission equipment along with the standard camera components. And as I always say – You get what you pay for! If you pay $100 for a wireless equipment I can just imagine the snowy picture in your future, or no picture at all.
So be very specific with the manufacturer of the equipment and make sure they know and understand what your needs are before placing an order. A few extra minutes in the beginning can save you a lot of money and hassle down the road.
