Typical Questions Regarding Wireless Security Transmission Devices

Usually when business owners set up their first wireless security camera systems they have some simple questions that usually are asked:

A frequent question is, Should I record sound with a surveillance camera system?

Its complicated, audio recording is not permitted as evidence in court or legal proceedings therefore it cannot be used. According to the United States legal code audio recording should not be As an example, surreptitious or covert use is audio that is recorded from a hidden unit. Therefore, if the surveillance cameras are in open and in plain sight then sound recordings are viable. But, if the surveillance units are hidden or to small to be noticed, such as a spy camera, then audio should not be used.

Hidden cameras would consist of pin hole and tiny cameras and virtually all spy cameras, like a radio containing a hidden camera within. Sound recording in a hidden camera or miniature camera is restricted to law officers and law enforcement agencies. The exception is using body worn cameras, such as, a hidden camera in a wrist watch or a hidden camera in a tie clip and so forth. Refer to Title 18, Section 2512.

Many new users also wish to know what the difference is between a wired and a wireless camera system?

The wired security camera system uses a coaxial cable connecting the security cameras to the recording device such as a DVR/ VCR recorder, or live monitor such as a TV monitor. The wireless security camera has a built-in or attached wireless transmitter that sends the video data from the camera to the receiver device. The wireless receiver unit then connects to the DVR or the viewing monitor.

If you are utilizing a wireless security camera system it is important to think about how far the wireless cameras are located from the receiver device. Standard wireless security cameras are able to transmit signals up to 1000ft. while high power wireless security cameras often transmit asfar as 2500ft.. These optimal distances are based on clear line of sight transmissions. Transmissions cover much shorter distances if they must pass through multiple walls, barriers, or competing wifi tranmissions present between the wireless cameras and the wireless receiver unit.

The most frequent cause of wireless transmission interference comes from cordless and cell phones. Cell and cordless phones operate using the 2.4 GHz frequency and will cause interference with 2.4 GHz wireless security camera systems. Fortunately interference is usually minimal and usually only if the phone is directly between the wireless camera and the receiver unit. Other causes of bad transmission include wireless Internet, networks and WiFi.

The interference coming because of walls and other barriers is usually minimal. You will find 2.4 GHz wireless security cameras will send and receive through walls up to 2ft. in thickness, providing the wall does not contain a high proportion of metal.

What about having multiple wireless security cameras in one location?

Most wireless surveillance camera setup has more than simply a single camera. You will see that most systems provide up to 4 wireless security cameras in one area. This is because every device is sending its signal using a minor modification of the 2.4 GHz transmission frequency which is called the channel. Any in excess of 4 then the transmitting surveillance cameras will start to cause interference for each other.

If you want to view all four wireless feeds from the four surveillance cameras at once that will require 4 separate pairs of wireless transmitters and receivers. You can use a single wireless receiver with 4 transmitters only if you are willing to switch back and forth to each channel. You can only view one camera at a time if you choose to utilize only one receiver. When using multiple wireless cameras in a single location you will have to set the DIP switches for each transmitter to a different channel.
