Many business managers and owners discount the idea of installing a CCTV system on their premises. Worried about costs and benefits, they use other security measures to protect their stock and their staff.
CCTV systems could be more beneficial than you think. Here are three key ways that CCTV can help to protect your business.
Deterrent
Although they won’t stop all crime, it is thought that visible CCTV systems act as a deterrent to would-be criminals. It’s far less risky to steal from a shop with no CCTV than from one that explains its system clearly in a window poster and which has highly visible cameras. The presence of a camera at the entrance or exit of a building and watching over key areas like retail sales floors or IT suites can make the difference between your business being targeted and the criminal moving on.
Evidence and Interference
Depending on the type of system you install, CCTV has the potential both to stop a crime before it occurs and to provide the police with valuable images that can help them to detain a suspect. Monitored systems, where the images are fed from the camera to a real-time monitor, allow security staff to see what’s happening at the premises at all times. If they pick up anyone behaving suspiciously they can alert staff on the ground who may be able to prevent a crime. Recorded systems, on the other hand, should give vital information on the appearance and activities of any criminals, which can make a huge difference to a police investigation.
Peace of mind
For anyone working in, shopping in or visiting your business premises, the knowledge that there is a working CCTV system in place brings peace of mind. Not only does it let your employees know that you are concerned for their safety, but customers and visitors recognise it as a deterrent and automatically feel safer than in a business where there are no cameras at all. Whilst not everyone likes the presence of CCTV cameras in public places, most people would say that such systems make them feel more comfortable.

2 Way Radios
Frequency Considerations for Recreational 2 Way Radios
If you are in the market for 2 way radios for personal use, you have an immediate and important choice to make: What radio frequency band do you require?
Frequency! 2 way radios obviously utilize 'wireless' communication methods so when using a 2 way radio you are transmitting and sending your message through the air -- the same air that is currently carrying television signals, commercial radio signals, Ham radio signals and literally thousands of signals from other private 2 way radios. The Federal Communications Commission (FCC) has the job of controlling all of these communication signals so they don't run into each other; to accomplish this they have reserved frequency bands for use by certain types of communication (signal sending) devices. There are two frequency bands in use for recreational 2 way radios, these are called Family Radio Service (FRS) and General Mobile Radio Service (GMRS).
In 1996, the FCC reserved a set of radio frequencies they called the Family Radio Service (FRS) band, specifically for short-range 2 way radios (radios that operate no more than 2 miles away from each other) with a small power output (up to 500 milliwatts or one-half watt).
About fifty years before the FCC created the FRS band they had reserved a set of frequencies for higher power 2 way radios that operated over a longer range this is the General Mobile Radio Service (GMRS) band. The GMRS band is for radios with a power output between one and five watts and a range over 2 miles. The FCC regulates the 2 way radios that operate on the GMRS band and requires users of this type of radio to obtain a license and pay a fee. The GMRS license is good for five years and costs $80.00; the license must be obtained by an adult (the radios operating under the license may be used by minors but only with the licensed adult's knowledge and permission). Go to the FCC's Internet page at: http://wireless.fcc.gov/services/index.htm?job=service_home&id=general_mobile
for more information on GMRS licensing.
When buying 2 way radios, your choice is between a set of radios that operates only on one of these frequency bands or a set of radios that is able to operate on either one of these frequency bands. This determination will obviously have to be made based on the maximum distance the radio users will be from each other. If the radios are to be used within two miles of each other, FRS will be the best (and least expensive) choice. If a greater distance is consistently required, 2 way radios that operate on the GMRS frequency band will be required. If the need for distance is uncertain or if you want the option of occasionally transmitting up to five miles a FRS/GMRS hybrid is the radio set to choose.
