No you cannot. According to United States federal laws, audio should not be used in a surreptitious manner. One example of surreptitious interception is audio in a hidden camera. This includes pinhole board cameras and all covert or hidden cameras; i.e., a clock radio. Audio in a hidden camera or board camera is only available to law enforcement agencies. Title 18, Section 2512.
Wired cameras have a video cable that runs from the camera to your recording or viewing device such as a DVR, VCR or monitor. Wireless cameras have a built-in transmitter that sends the video signal to a receiver. The receiver connects to your recording or viewing device.
Standard wireless hidden cameras can transmit up to 1000 feet and high-powered wireless hidden cameras can transmit up to 2500 feet.
You can have up to four wireless cameras in one location. You can view all cameras at once using four receivers or you can use one receiver and switch to each camera.

All of our wireless cameras operate on the 2.4 GHz frequency. Range varies from 200' to 700' depending on environmental conditions. These units are FCC approved.
The transmitters used in all of our wireless systems are FCC and Industry Canada Certified.
CCD is used in professional cameras because of it's high resolution quality and it's ability to record in low-light situations. CCD is basically a small silicon chip that receives light and turns it into voltage variations which makes up an image. It's usually measured in inches with 1/3" CCD being the standard. They are higher priced but are great for cameras that may require vision in near darkness.

DVR Cards enable the user to convert their computer into a Digital Video Recorder. The DVR Card(s) is typically installed in an available PCI slot of a computer. DVR cards are bundled with video surveillance software which allows the user to record and display multiple cameras simultaneously from the camera site or a remote location.
A Digital Video Recorder (DVR) system records high resolution digital images to a hard disk drive (HDD) and eliminates the requirement of maintaining VHS tapes. Since the video images are stored digitally, the image quality will not degrade overtime, as would a VHS tape when recorded over multiple times. The time-saving search capabilities of a DVR will enable the user to locate the desired video clips via user defined parameters (camera, time, date, etc.) versus the fast forward and rewind functions of a VCR. A DVR can be accessed remotely from anywhere in the world using the Internet.
The amount of time a DVR will record for is based on the size of the DVRs hard drive, the number of cameras recording and the number of frames per second it is recording at. Our stand alone DVRs uses 3.4GB per camera per day. 4 camera stand alone on 250GB hard drive will record for 18 days. 8 camera stand alone on 250GB hard drive will record for 9 days. 16 camera stand alone on 500GB hard drive will record for 9 days.
You can use your own VCR for recording. However, the VCR will have to be recording all the time. Most VCRs can only record for about 10 hours but we have special VCRs that can record up to 1280 hours.
It is an RCA Video plug and a power plug on the camera for easy connection to VCR or TV. This is done by running the RCA (Aux) line into the VIDEO IN of the VCR or TV. The TV or VCR must be set on the correct channel to view the VIDEO IN picture.

A varifocal lens is one where the focal length of the lens can be varied. This is a fancy way of saying it is a zoom lens. Most varifocal lenses have, and in almost all circumstances should have, an auto iris feature.
A fixed focal length lens cannot zoom. The focus is fixed. A fixed focal length lens usually allows more light to pass through the lens at a given focal length than a varifocal, or zoom lens. This can be important in low light situations.
