Security cameras can be a valuable investment when it comes to protecting your business. They act as a deterrent to help cut down on theft or break-ins. If a crime does occur, the surveillance footage can be used to help catch the thief. Outdoor security cameras can be used to monitor parking lots and entry points around your facility and can help keep your business and your employees safe. When you are shopping for outdoor security cameras, of course you will want to make sure the cameras have a rugged, weatherproof housing but the ability to withstand the elements is just one of the things you should look for. On this page we are going to cover some of the other important things to consider before you make your purchase.
How Many Cameras Will You Need?
One thing to think about is how many cameras you will need to adequately cover your property. You may want to have the parking lot covered from one or more angles and you will want to have a clear view of all doors, windows, and other entry points. The company you decide to buy your cameras from should be able to give you some recommendations on how many cameras you need and where you should position them.
Low Light Conditions
It’s important that your security cameras have the ability to produce clear images whether it’s daytime or nighttime. A lot of crimes happen under the cover of darkness and you will need to be able to see what is taking place on your property whether it’s a clear, sunny day, or it’s the middle of the night.
CCD Versus CMOS Image Sensors
To record images, security cameras will either use a CMOS sensor or a CCD sensor. These sensors convert visible light to electrical signals which are then converted into pixels that make up the images we can view on a screen.
A CCD sensor is an analog device that captures light and turns it into an electrical charge, one pixel at a time. A CCD sensor uses more power than a CMOS sensor and is normally used for hardwired security systems.
A CMOS sensor will also convert visible light into electrical signals but because they use less power than CCD sensors, CMOS sensors are used in a lot of portable devices and they are also used in wireless security cameras.
Wired Versus Wireless Security Cameras
Wireless security cameras are faster and easier to install because they don’t require you to run hundreds of feet of coaxial cable connecting the cameras to the video recorder. Despite that one advantage, there are a number of drawbacks to a wireless system. Wireless security cameras are generally not as reliable as a hardwired system. Many wireless security cameras are line of sight systems that means the camera must have an unobstructed path to the receiver, this can cause some pretty serious limitations. Wireless systems also need a power source so although you won’t need to run coaxial cable from the camera to a recorder, you will either need to connect the cameras to a power supply or make sure the batteries remain charged.
When it comes to outdoor security cameras, a hardwired system is usually a better choice. It may be a little bit more expensive to have them installed but you will get superior video quality and you won’t have to worry about interference that can be a problem with wireless systems. Wired security cameras can also be installed hundreds of feet away from the video recorder and line of sight from the camera to the recorder is not a problem you will have to worry about.
The items mentioned on this page are just some of the things you should consider before purchasing outdoor security cameras. If you take the security of your business seriously, you should consult with a professional about what types of cameras would be best for your situation, as well as how many cameras to buy and where to position them.
