The Outer Limits of Digital Storage
Do you need any special licensing to sell and install CCTV?
Should we use regular coaxial cable or mini coaxial cable for CCTV installations?
Should we use video tape recorders or a digital recorder on our CCTV projects?
When considering a multiple camera project what should we look for at the customer site to provide an optimum picture for the client?
How do I factor in light reflectance when quoting the job?
What is light reflectance?
Our installation area has many electrical storms. Should we consider any special devices to protect the camera power, communication control signals and camera dome?
What should our sales engineers look for when the customer asks for alarm call up of preset positioning of the video system?
When our company is specifying and an exterior power supply for video or card access applications what should we consider a sufficient product?
Our technicians are always running into field issues with 12VDC or 24VDC power. The sales team always mixes product either in the choice of cameras or the power supply. Is their field device we can purchase off the shelf that gives us more flexibility between 12VDC and 24VDC applications?
Our technicians were discussing the quality of recent video installation and were confused why they had two cameras the same quality in the same lighting but different distances and one camera looked different. The customer has come back to the salesman and asked him to either fix the problem or take the CCTV out. Why do we have this issue?
Why was the video multiplexer created and how does it work?
How many different multiplexers exist and are available for sale?
Why during playback using multiplexers and VCR do some camera images jump around?
Our customer is questioning if our video digital recorder uses a Static or Dynamic IP Addressing scheme. Could you provide a brief understanding of each IP scheme?
Could you give me an idea of the time it takes to download large a file compared to 640X 480 color image.
Our corporate clients are always inquiring about how much our video security devices will use of network bandwidth if we recommend the use of corporate networks for security communication solution. Could you give me a quick run through of Ethernet networks, POP's and measuring bandwidth?
DSL is now available in our area. What do I need to know about DSL and video applications using DSL?
