Should You Choose Wireless? 1

If you’ve ever considered wireless cameras as a solution to your home or business security application, you may have discovered that “wire-less” does not equate to “less money” or “no wires”.  It always leaves me puzzled when I receive a call looking for something “simple, easy to install, inexpensive, and oh yeah – wireless”.  The terms ‘inexpensive’ and ‘wireless’ are somewhat of an oxymoron, as with all things, we pay for technology and convenience.

One of my recent wireless consultations included having to explain why ANY cable would need to be incorporated, and why power would need to be accessible at the wireless camera location?  Depending on the unit you may be considering, here are a few tips when it comes to selecting wireless:



Determine Distance

What is the distance that video needs to be transmitted?  This often determines the size of the transmitter/receiver combination that needs to be utilized.

For example, the TCO-5808 (from VideoComm) receivers permit users to transmit 2000′ , 1 mile, or 4 miles, depending on the application and the optional antenna you choose.

Do I have line of sight, from the camera to my receiver?  Any kind of obstructions such as walls, trees, or buildings can cause a potential loss of video, and therefore poor operation of a wireless system.

Like-Frequencies Disrupt Signal

Are there any other wireless devices being used in the vicinity?  Many times like-frequencies can play havoc on each other, disrupting video transmission.  Be sure to note microwaves, hand-held land line telephones, etc.

Oh, and You Need Power

Power is needed at the camera, as well as at the receiver.  Unless one incorporates solar panels and batteries as power supplies, be prepared to have power accessible.

Accessibility to Power

Bottom line, wireless technology, for the right application – works great!  Otherwise, if cabling is possible, or if line of sight does not exist, plan on pursuing the more traditional hard-wired method.  It could quite possibly save you money and frustration.
