Surveillance Systems Frequently Asked Questions
Frequently Asked Questions
1. What is a Quad?
A Quad is used with a VCR or other single channel-recording device that splits your monitor into four sections allowing you to view four cameras at once.
2. Will a Quad allow four cameras to record at the same time?
Yes, you can record all four cameras at the same time. You can also record using a switching monitor, which will record the camera that is showing at that moment.
3. What is a 2.4 GHz wireless frequency?
A frequency is used to transmit a signal or data like video. 2.4 GHz 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. These units are FCC approved.
4. Are the transmitters FCC approved?
The transmitters used in all of our wireless systems are FCC and Industry Canada Certified.
5. What is CCD ?
CCD is used in professional cameras because of its high-resolution quality and its ability to record in low light situations. CCD is a small silicon chip that receives light and turns it into voltage variations which makes up an image. It is 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.
6. Do the receivers work through walls up to two feet thick?
Yes, as long as there is not excessive amount of metal in the wall.
7. 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, CA-100 and CA-150.
8. What is a Plug and Play connection camera?
It is a 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.
9. What is the difference between a PC based DVR and an Embedded (stand-alone) DVR?
A PC based DVR has all the functions of a computer. An embedded DVR functions only as a DVR.
10. 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. Our stand-alone DVRs uses 3.4 GB per camera per day. 4 camera stand alone on 250GB hard drive will record for 18 days. Eight cameras stand alone on 250G hard drive will record for 9 days. 16 camera stand alone on 500GB hard drive will record for 9 days.
11. How many cameras can be hooked 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.
12. How long will the camera last with a 9-volt battery.
The BD-127 will last 5 hours.
13. What is the operating voltage of a camera?
Our cameras range from 9 volts (CMOS) to 12 volts, and 24-volt profession models.
14. Between what temperatures is it safe for cameras to operate in?
It is safe for B/W cameras to operate between -23 degrees C to +50 degrees C or -10 degrees F to +122 degrees F. It is safe for color cameras to operate between -23 degrees C to +40 degrees C or -10 degrees F to +104 Degrees F. It is safe to store cameras between –30 degrees C to +70 degrees C or -22 degrees F to +158 degrees F.
15. What is a varifocal lens?
A varifocal lens is one where the focal length 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.
16. What is a fixed lens?
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.
