Q: What's the difference between a wired camera and a wireless camera?

A: A wired camera needs a cable that goes from the camera to a TV or VCR. The video signal is passed from the camera, through the cable, and to your TV or VCR, which allows you to see the picture. All wired cameras must use RCA cable to connect the camera to the TV or VCR.
A wireless camera does not need an RCA cable connected from the camera to the TV or VCR. The video signal is transmitted through the air to the TV or VCR directly, or to a receiver.

Q: Is it possible to experience interference with 2.4Ghz wireless equipment?

A: Is it possible to experience interference with 2.4Ghz wireless equipment, and what can possibly cause the interference? 　　
It is possible to experience interference from 2.4Ghz phones or wireless internet. Also garage door openers, alarm systems and other devices on the 2.4Ghz frequency can cause interference. Microwave ovens and similar devices can also cause occasional interference.
Some 2.4Ghz phones or wireless internet solutions have a setting that allows them to identify the frequencies in use and select different frequencies while others may have to be switched manually using a "channel" or other button on the phone/transmitter or on the receiver.

Q: what is difference CCD and CMOS?

A: what is difference CCD and CMOS? CCD image sensor could provide better picture quanlity than CMOS with higher price.
If you have advantage requirement on picture, we strongly recommend purchasing CCD cameras.

Q: Do the wireless cameras and transmitters provide encryption?

A: No, our wireless cameras and transmitters do not send encrypted audio/video. In order for somebody else to receive audio/video from your transmitter they will need to have a wireless receiver set to the same channel within range of the transmitter (700 ft. maximum). The chance of this happening is very rare.

Q: What is Horizontal Resolution?

A: Horizontal Resolution is a professional standard to evaluate the quality of TV picture.
TV lines are the measure unit. The higher horizontal resolution means the better picture quality.
For example, the horizontal resolution of DVD is 520 TV lines, and regular broadcast TV only get 330 TV lines, VCD is 240 TV lines, VHS is 220 TV lines.

Q: How many wireless cameras can be used together?

A: As far as now, the maximum number of camera working together is 4, and you need make them depart from each other more than 10 metters distance to avoid possible interference .
So we strongly recormmend that up to 3 cameras, that could get more clear pictures.

Q: How do wireless cameras work?

A: The camera connects to power...i.e. plug into a wall outlet or use a battery pack. 　　
The receiver connects to power...i.e. plug into a wall outlet or use a battery pack. 　　
The camera and receiver can only be a specified distance apart. (Just like your cordless phone needs to stay only a certain distance from its base) 　　
The camera sends wireless "real time" video to the receiver.

Q: How do I record the video?

A: The receiver connects directly to any recording device with a "video-in" port using a standard RCA cable. (The same type cable you use to connect your VCR to your TV) 　　
Most popular recording devices: VCR, DVR, Computer, or camcorder

Q: How do I view the video?

A: The receiver will connect to any TV or monitor using a standard RCA cable to the "video-in" port. Remember Wireless is advertised as L.O.S. (Line of sight) The actual distance you will get varies depending on the conditions and the placement of the units. 　

Q: What is Resolution and Lux?

A: Resolution refers to the cameras ability to reproduce images.
The higher the resolution, the better. Lux refers to the amount of light that is needed for the camera to see.
This becomes important if you need the cameras to see in low light. The lower the Lux, the better.
