 Wireless Cameras
While we would always recommend the use of a wired system for
reliability, sometimes its not possible to get the wires to the camera
without causing a large amount of inconvenience.
In these situations, a wireless system provides the solution to the
problem of signal transmission. Wireless comes in two forms with regards
CCTV systems:
1. Analogue video sender system. This is more suited to a composite video
cameras, and transmits the video signal at 2.4Ghz, in much the same way
television is transmitted. These devices have disadvantages in that they are
susceptible to interference in the same way television is, and they also
conflict with wireless networking devices that are now very common. Analogue
senders are also typically limited to four channels for transmission. Each
camera must have exclusive access to a channel, so in any given area, this
would allow a maximum of four wireless cameras.
2. Wireless IP/Network cameras. These are cameras that have a built-in
wireless network transmitter. They participate on a wireless network in the
same way as normal computers do. These provide image integrity due to the
error detection and correction inherent in the wireless networking
technology, but also have a shorter signal range. The advantage here is the
large number of cameras that can participate in this technology.
When we recommend wireless systems to our customers, we prefer the
digital approach using wireless network devices, as the flexibility and
reliability are far superior to an analogue system.
We have also used analogue sender systems on small-scale mobile cameras.
These work well where power also needs to be mobile, as digital network
cameras often require a substantial power supply to operate. We have even
installed an iCatcher system on a 4 x 4 model car with a wireless video
link.
Please take a look in our CCTV shop
for a selection of products for use with wireless technology.
The picture in the upper right corner shows an Axis
206W wireless IP network camera. These cameras still require a substantial
power supply, and thus are recommended to be plugged into a nearby mains
socket using the supplied mains adapter.
