]]> When buying a video security camera system it is very important to choose the right CCTV lens. The focal length of the camera lens should be one of the first things you consider. The lens can cover areas from 90 degrees,to view wide areas, all the way down to 15 degrees to read license plate. People often make the mistake of using one CCTV camera to cover a large area such as a parking lot. But to see real detail you need to use multiple security cameras with a mixture of wide and tight angle CCTV lens.
With a vari-focal lens the focal length can be adjusted and locked in to give you the proper view of your property. CCTV cameras mounted over a door should have a tighter lens to identify people, while cameras mounted in a room should have a wider CCTV lens for general viewing.

]]> Most people don’t know how to choose a video security camera system.  The first thing you would do is to figure out how many cameras you would need.  The homeowner would want to cover the backyard, the side yard and the front yard.  Typically, you would use infrared bullet cameras, which would allow you to see in low light conditions or complete darkness.  The next step would be to choose your digital video recorder.  Digital recorders come in four, eight and sixteen camera models.  You can also choose the amount of hard drive you want, from 500 gb to 4 tb.  The larger the hard drive, the more storage space you have.  The next step would be how to choose how to view  your cameras. They can be viewed live on site with an LCD monitor, or through the internet using your DSL connection.  The most important thing is to make sure you have a CCTV installer with lots of experience.  M & J Video has been in business for 28 years, installing video camera systems in 1,000 of homes southern California, as far as Santa Maria and Santa Barbara to Palm Springs and Indio.  You can trust our video installers to do a complete, clean and thorough job, with a free, one year, on-site technical support guarantee.  Of course, you will need the cost of your CCTV system up front, and M & J Video will give you a free estimate right over the phone.
