Step #4 - Lighting Conditions - Exterior lighting conditions change often during the day. This of course affects the quality of the images that the outdoor security cameras record.
Some cameras can record clearly in low light conditions. They have a lower lux rating. Other cameras require more light and have a higher lux rating. Make sure the cameras are positioned in such as way as to make the most of the available light, but never pointed towards direct sunlight.
Consider installing automatic lenses on your cameras to help you achieve quality-recorded images even in poor daytime lighting conditions. Night vision cameras are probably your best choice. They can record clear video in total darkness. Yes, they typically cost a little more.
Step #5 - The Right Back-End System - Each home outdoor security camera will connect to a back-end system or device that will be able to monitor and record the video images.
This can be your home PC or a dedicated DVR (digital video recorder). DVRs cost more but they are built specifically for this purpose. They are the better choice.
They come with huge hard drives that can record endlessly. They also have Internet capabilities for remote viewing. PCs are cheaper to configure, but require more technical skill. Your PC will require software, and the installation of one video capture card per camera. You must also make sure everything is compatible with your computer’s motherboard and operating system.
If you do use your PC as your back-end, consider choosing "motion sensor" outdoor security cameras. They will record the video images only when triggered my motion. This will be much easier on your computer because it will use up less hard drive space. With a little configuring and an Internet connection, your PC can also be set up for remote viewing.
Step #6 - Put It All Together - By having followed all the steps in the above tutorial (both Part 1, and Part 2), you’ve planned your surveillance and decided on what you want as a home outdoor security camera system.
Now put it all together by comparing this list against the DIY security camera kits that are available out there. You may not find a perfect fit, but you’ll be in better position to choose the right DIY exterior security cameras and system.
