I found a cool website that sells monitoring equipment as their specialty. Here's a link to their official website: http://www.2mcctv.com/ I hope that helps you.
Yes you can upgrade form a 4 camera system to an 8 camera system by adding to your current 4 camera a cctv security camera system. Or you can also buy another cctv security camera system and connect it to your current system.
A cctv system is a security system, mainly a security camera. It's used to transmit a signal to a specific place.
You can find a cctv system in many stores like best buy, circuit city and many others becareful and make sure you purchase the best one though. I like the cctv system definatley purchase one.
One can buy a CCTV system in China from the Borsche CCTV website. They are also available to buy from Swan CCTV or online from eBay either used or new.
One can get CCTV home security from many different stores locally. Home Depot and Lowe's are two places that one can buy it from. Some retailers online such as Home Security Store and Amazon also has it.
The CCTV Company specializes in camera surveillance and security systems for businesses and homes. The security system is to be the technical version of a security guard.
When you're setting up a CCTV security system, you will obviously want to do what you can to mitigate the sometimes overwhelming cost that can be associated with these systems. One of the best things that you can do is to buy individual components over time, whenever you find them for cheap. This is because companies will often charge more for 'sets' due to their convenience. If you're a little patient, you can slowly build up your CCTV security system with individual components for a drastically lower price than you'd pay for one of those more convenient CCTV security system sets.
If one wishes to purchase multiple CCTV recorders then one may wish to visit a specialist security store. These include Discount Security Cameras, CCTV 42 and Security Stores.
Video security CCTV can be purchased online at the manufacturing website, or through your local salesman. They are available at a comparable rate to purchase.
A CCTV DVR systems is a monitoring program. It won't alert you if a burgular breaks in. A CCTV is a poor choice for home security in my opinion, so you're better off with the other.
There are a variety of things a CCTV DVR can do. They have the ability to save home security video and audio to a hard drive. You also have the ability to save footage from a number of security cameras on one CCTV DVR.
CCTV is an excellent idea for home security. Not only will you have a security system that will alert you if an intruder is near your home, you'll also have a surveillance system so you can watch any activity going on outside.
