What is the difference between a wired and a wireless camera? - 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.

How far can a wireless hidden camera transmit? - Standard wireless hidden cameras can transmit up to 1000 feet and high-powered wireless hidden cameras can transmit up to 2000 feet.  Most of the time 200 to 300 feet is more than enough.  These hidden cams are top quality.

How many wireless cameras can you have in one location? - Normally yu can have up to four wireless cameras in one location. You also can view all cameras at once using four different receivers or you can use one receiver and switch to each camera which is commonly use.

Will a cordless phone interfere with wireless cameras? - Cordless phone that operate on the 2.4 GHz frequency will cause interference with 2.4 GHz cameras. Interference should be minimal and usually occurs if the phone is between the camera and receiver. So placement is important.

What is a 2.4 GHz wireless frequency? - A frequency is used to transmit a signal or data like video. 2.4GHz is the specific wireless frequency that our transmitters use to send video signal to a receiver. All of our wireless cameras operate on the 2.4 GHz frequency. Range varies from 200' to 700' depending on environmental conditions. All the units we offer are FCC approved.

Are the transmitters FCC approved? - The transmitters used in all of our wireless systems are FCC approved and Industry Canada Certified.

What is CCD? - 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.

What is a Quad? - A Quad splits your monitor into 4 sections allowing you to view 4 cameras at once.

Do the plug and play connections require extra wire to run the signal back to the VCR or TV? - Yes, you need to buy the length of cable you need we offer the CA-25, CA-50 and the CA-100.

What is the difference between a DVR and a VCR? - 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.

How many hours will a DVR record? - 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. One camera recording in Real Time uses 1 GB per day. So a 16 camera system will use 16 GB in one day.

Do I need a VCR from you or can I use my own VCR? - 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.

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.

What is a Plug and Play connection camera? - 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.

How many cameras can I hook up to one TV? - You can hook up as many cameras as your TV has inputs. Most TVs have 2 inputs but when using a quad you can hook up four cameras.

Do I need a VCR to record or will the cameras record? - You must have a VCR or DVR if you want to record.

How long will the camera last with a 9-volt battery? - Example a Cyber Eye and BD-127 will last 5 hours.

Between what temperatures is it safe for cameras to operate in?
Safe for B/W cameras to operate between --10ºF to +122ºF
Safe for color cameras to operate between --10ºF to +104ºF
It is safe to store cameras between -22ºF to +158ºF

What is the operating voltage of a camera? - Our cameras range from 9 volts (CMOS) to 12volts, and also 24 volt professional models.

What is a vari-focal lens? - A vari-focal 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 vari-focal lenses have, and in almost all circumstances should have, an auto iris feature.
