A security camera can come in many different styles including dome, bullet, infrared and c-mount. The security camera that will work best for your application will depend on several factors such as whether you will use the security cameras inside or out, during the day, nighttime, or both.

There are four types of lenses for CCTV use: Fixed Aperture, Manual Iris, Auto Iris, and Zoom. If the area you wish to observe experiences infrequent changes in light, use a manual iris lens, which can be adjusted for light only by hand. If the area the Security Camera will be observing experiences frequent changes in light, use an auto-iris lens. These lenses adjust to light changes automatically. Auto-iris lenses come in Video or DC, and cameras generally support one format or the other. Be sure your lens matches the camera. To perform close-ups, get a zoom lens, manual and motorized zoom lenses are easily available from most retailers.

First, you will need to connect your DVR to your local area network using a router and standard RJ-45 Ethernet cable. Your DVR system will be assigned an internal IP address by your router, typically something like 192.168.1.25. You can get the internal IP address by opening your router configuration and checking for connected devices. Once you have your internal IP address, you can view any of your cameras from any computer on your network by opening Internet Explorer to your DVR’s internal IP, for example, http://192.168.1.25.

Next, you will have to open two ports on your router. The default ports are 9000 (for the camera streams) and 80 (for the Web interface). If these ports are not open, you will be unable to view your DVR from a remote location. To learn how to forward ports on your router, consult either your router’s manual or http://www.portforward.com. Remember that you need to forward these ports to the internal IP of your DVR system, which we discovered in the previous step.

Once you have successfully forwarded the ports, you can access your camera feeds by dialing in to your external IP address. To get your external IP address, simply visit http://www.whatismyip.com and write down your IP address, for example, 74.197.152.44. If you are on a cable or DSL connection, this address may change, so be sure to check once in awhile or use Dynamic DNS service. To view your camera remotely, you can open the corresponding URL in Internet Explorer, http://74.197.152.44, or you can use the included software that came with your DVR called Net-Viewer.

Remote viewing is available for both live and previously recorded feeds. Easily viewing your DVR feed remotely is just another benefit of using Gadspot for all of your DVR needs.

Measuring your camera's field of view is vital to knowing how many cameras you need in order to monitor your premises. Deciding the necessary field of view prior to purchasing cameras can ensure that your final camera arrangement offers complete coverage without blind spots.

Understanding field of view requires an understanding of how security camera lenses are marked. Typically, a camera will include documentation specifying its CCD size and lens size. Typically the CCD is marked as 1/4" or 1/3", but other sizes exist as well. Lenses come in all sizes from a few millimeters to 200 millimeters.

After determining your lens size and CCD size, visit http://www.sweeting.org/mark/lenses/cctv.php and select your camera information. The on-screen calculator will provide details about the angle of view that the camera will have. Remember that viewing angle is a three-dimensional aspect, and each lens configuration has a different horizontal AND vertical viewing angle. Be aware that the viewing distance increases far away from the camera, so avoid blind spots by placing every camera within the field of view of another camera.

If you have discovered blind spots in your camera configuration, increasing your camera field of view is a priority. The easiest way to increase your field of view is to simply add another camera or change the existing camera arrangement. If this is not feasible, or you have not yet purchased one yet, consider purchasing a camera with a smaller lens that has a wider field of view.

Depending on where you live, your country may use any one of three video standards:

* NTSC (National Television Standard Committee), developed in the U.S. in 1953, is used in North America, most of South America and Japan, and it provides video resolution up to 525 lines.

* PAL (Phase Alternating Line), developed in Europe in the early 1960s, provides up to 625 lines of resolution, and it’s used in most other areas of the world.

* SECAM (Sequential Color Memory), which also provides up to 625 lines of resolution, is much less common but is used in France and parts of Eastern Europe and Africa. (PAL usually works for SECAM.)

NTSC and PAL are not compatible. To make sure you’re choosing the right CCTV, be sure you know which video standard your country uses before you make your purchasing decision.
