best buy security cameras home monitoring image
Luis B
I want to buy a great CCTV system.
Answer
IP = "Internet protocol". These CCTV cameras have a chip in them that basically turns them into a "video server" with an IP address like any other node on an IP based computer network (like the LAN at your home or office that connects to the Internet). IP based cameras can be password protected and can be accessed from other computers on the same local area network that the computer connects to and can be accessed remotely over the internet if the LAN allows remote connection. You can see what the IP camera sees using a browser. The IP camera can send video or stills to a file server on the network for storage and later viewing if needed.
Analog CCTV security cameras can connect directly to a TV (the Yellow RCA jack monitor port used by game consoles) or they can connect to a multi-channel DVR (they come in 4, 8, 9, 16 or larger channel sizes) and the DVR can connect to a monitor. Most newer security DVRs can also be assigned an IP address so seeing what those analog cameras can see using a computer and a browser. The DVR has a hard drive and is the "server" for storing the captured video.
Certain IP cameras have additional functions that can be controlled by the browser software (using Java) that allows for panning, tilting and zooming. Certain analog cameras allow for panning, zooing and tilting, too, but use a wired or wireless controller - this may be direct connection to the PTZ unit the camera is mounted to or through the DVR.
So basically, there is not a lot of difference between the two - just the communication protocol and method. One is digital and the other is analog (but stores the digital information on the DVR). Just because the IP camera is digital does not make it "better" - it depends what your surveillance requirements are - both camera types will meet your needs - it depends what your budget can stand.

How do I go about buying products wholesale from a certain company?
Q. How do I go about buying products wholesale from a certain company?
I want to start my own business, and would like to purchase products wholesale from a certain company, instead of buying them from, say, Future Shop and having to pay a bumped up price then bump up the price even more to make profit, if you understand what I mean! So basically I would just like to know how I would go about purchasing products wholesale from a certain company in order to sell them for a reasonable price from my business...Thanks!
