Security Cameras Dec 1st, 2016. Site last updated by PHA.Which Security Cameras Should You Use?Are you looking for the right type of security cameras. Over the years of business we have installed many different makes of security cameras. From economy grade analog cameras to top of the line digital cameras. Even some that were rated the best, just to find that they did not hold up over time.For economy cameras systems I would say, remember you get what you pay for. We have found a very affordable Economy DVR to go with the cameras. I would not recommend anything less then 700 tv lines when shopping for economy cameras.We have put together a couple digital HD camera system packages Listed here.Lilin Brand Cameras are our go to security camera system. We have some recorded videos from some of our camera systems Click Here to see the videos.We have installed a few auto tracking P.T.Z. cameras, They work good for a large parking lot, but not good for an area with a lot of video traffic. As far as P.T.Z. cameras are concerned. Unless you are watching live video feeds and want to be able to follow people around, Don’t waste your money on a P.T.Z. camera.Digital I.P. Based Cameras. There are many different makes and models here, and not all systems work with each other. But the best recorded video will be from a good digital system. A 1.3 meg camera is about the smallest resolution that you can get. these cameras are made to capture video at a focus distance of about 12 feet wide. A 2 meg camera is the most used in a system. They have a focus distance of about 20 feet wide and then they just get bigger and better.Fixed cameras, a fixed focus camera can be the best selection for a D.I.Y. camera system. This type of camera does not have the ability to be focused. You install them and point them at what you want to record. But you are limited with the depth and width that the camera is focused on. Usually about 15 ~ 20 feet from the camera.A vari-focal lens is one that you can adjust the zoom and the focus on the camera. Most come with the lens size of 3mm ~ 12mm. Not a easy setup, sometimes it takes a while to get it fine tuned.We have installed Acti, Samsung, Access, Luxon (hate them), lorex, Swann, Arecont, Xavee, Q-see, Axis, Vivotek, and many more types of cameras. One of the main prolems with digital cameras is when the NVR gets a firmware update sometimes the cameras also need to be updated. Which is a real pain.The next thing you need to know about is the P.O.E. switch it takes to power the I.P. based cameras. Make sure you get a good one that has full power to each P.O.E. output.We had top of the line Samsung cameras installed in a gas station for about 3 years, Slowly 1 after another they have started to go bad. If you power cycle them they would work again. But would drop out again with no pattern. Replaced them with Lilin cameras and have not been back.
