What is the difference between wired and wireless cameras?
Wired cameras have a video cable that runs from the camera to the video input jack on your
recording or viewing device. Wireless cameras have a built-in transmitter that sends the video
signal to a receiver. The receiver connects to the video input jack on your recording or viewing device.
What is the range of the wireless cameras?
The standard wireless cameras have a range up to 700 feet, depending on the number and type
of objects you are transmitting through. The commercial grade transmitter has a 15 mile line
of sight range (1000-3000 foot indoor range). Line of sight means there is nothing between the
transmitter and receiver, for example building top to building top.
Is a special recorder or monitor needed?
Any recording or viewing device with video input capabilities can be used, for example,
a VCR, TV, camcorder or computer.
How long can the cameras record?
The amount of recording time is dictated by your recording device. A standard VCR
can record for up to 10 hours if a T-200 tape is used. We also offer long play recorders
that will record for 24 to 960 hours on one tape.
What do resolution & lux mean?
Resolution measures the cameras ability to reproduce an image. The higher the resolution,
the better the picture quality. Lux is the measure of light the camera requires to reproduce
an image. The lower the number the less light the camera requires to reproduce an image.
Do the covert cameras have audio?
Audio is only available to law enforcement agencies due to federal law Title 18, Section 2512.
Are the transmitters FCC approved?
The transmitters used in all of our wireless systems are FCC and Industry Canada Certified.
Will cordless phones interfere with the wireless cameras?
Cordless phones that operate in the 900MHz frequency will not cause interference with our
wireless cameras. Cordless phones that operate in the 2.4GHz frequency will cause interference
with our wireless cameras.
What is the difference between a Digital Video Recorder (DVR) vs. an Analog VCR based video surveillance system?
The 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
intelligent search capabilities of a DVR will enable the user to locate the desired video clips via user defined
parameters (camera, time, date, etc.) vs. Fast Forward and Rewind functions of a VCR.
What is a DVR Card?
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.

Can a DVR record upon detecting motion or via a schedule?
Yes. Each camera can be configured independently to record upon video motion detection or via a schedule.
How do I access my video from a remote location?
The user may access the video from a remote location via a standard modem connection or a high speed internet/intranet connection.
What is the viewable area for your cameras?
The viewable area is determined by the cameras lens size (see lens chart below). Our covert cameras incorporate a 3.6mm lens.
