What is an Infrared Security Camera?

An infrared security camera offers the benefits of a traditional security camera with the additional advantage of infrared technology. Anyone who is considering the purchase of an outdoor security camera should definitely look into an infrared security camera. Outdoor cameras are built durable to withstand weather extremes and in many outdoor situations, the lighting levels cannot be controlled. Night time surveillance is impossible with a regular camera that cannot record during low light or no light conditions which is where the addition of infrared technology comes in extremely handy. This differs from cameras can function under low light conditions because infrared technology allows the camera to record in complete darkness.

The two primary factors should be user friendliness and functionality. It needs to be easy for a regular user to install especially for home owners looking to protect their property and family. The functionality is a whole other aspect that could get a little particular. The infrared security camera needs to hold up to the standards that will be required wherever it is to be installed. Indoor cameras do not have to stand up to as strict durability standards as outdoor security cameras.

Outdoor Security Cameras

A very common design is the bullet style camera for outdoor surveillance and is often mounted along the outside wall of a building. These cameras are capable of monitoring wide areas of space such as a parking lot and come with special casing or housing to protect the camera against different weather conditions. Infrared cameras allow the area to be monitored at night for any activity that might occur.

Infrared Camera Sensors

Infrared technology uses thermal imaging which reads the light wave emitted by any type of heat. Since these light waves are emitted during night or day, the camera can capture infrared images regardless of the light conditions. However, most people would prefer regular video surveillance and rely on infrared only when necessary. That is why most infrared cameras will come with dual functionality. That way it can record like a typical camera during the day and switch to infrared when it gets dark enough to set off the light sensor in the camera.

Buying and Installing

To buy the right camera you need to know what conditions the camera will be installed in. As with any outdoor security camera you want to make sure the camera is able to withstand the weather conditions. Otherwise an additional housing unit can be purchased to put the camera inside for protection. Make sure you plan the installation carefully to protect the wires from being exposed. Exposed wires can be tampered with if not protected and that will seriously compromise the effectiveness of your entire security system.

On advantage with an infrared security camera is that criminal will usually not know they are being watched in the dark so they don’t even think to disable the camera.

Dummy Security Cameras In Home Security


A dummy security camera is simply a something that imitates a real security camera but does not actually record or do anything a real camera would do. It is installed to look like a real camera with the intent of fooling would-be criminals away from vandalizing, stealing or engaging in some other destructive activity. A dummy security camera is used where a real camera would be too expensive or not necessary for the level of protection required. In home security, fake cameras are very useful since they are better than nothing and most homes do not require a functioning camera. Many homes do not even have lighting security so a fake camera with some lights will deter most burglars.

Making the most of a dummy security camera depends on how it is installed. There are some rules that the fake camera must be installed to abide by. For starters, the security camera should be only a complement to a real home security system. Second, the camera must appear real or it serves almost a detrimental purpose. Finally, for the camera to be effective it must be clearly visible since it uses the scare tactic more than anything. No criminal will stop for security devices they didn’t even know were there.

There is always more than one component to a full home security system. There are preventive systems such as motion activated lights which help keep petty crimes away from your property. Then there are reactive such as alarms and retroactive such as surveillance cameras to identify the offender. A security camera is retroactive and allows the criminals to be identified and it is up to the authorities to track down the offenders. However, a fake camera doesn’t offer this protection and really does little to protect you. Just as lighting security might discourage burglars but aren’t guaranteed to stop them, fake outdoor security cameras work the same way. A would-be burglar walking across your yard might spot the outdoor security camera and turn around. But you still need the rest of the security system such as alarms and such to protect your home in case the burglar decides not to turn around or does not see the cameras.

Since the strategy of using a fake camera relies on the scare tactic the camera has to look convincing enough to a criminal. Cheap cameras will not look as authentic and any less than authentic is pretty much worthless to your security system. A good quality dummy security camera should not have cheap plastic lens and thin cables that do not look real. Invest the extra couple of dollars in a fake camera that looks real. Try going for a camera that has motion sensors and can perform pan-tilt motions. For outdoor security cameras, treat it like a real camera and invest in a security camera housing casing.

Wireless Outdoor Security Camera Features

A wireless outdoor security camera offers many advantages that just any security camera cannot. It is proven that homes protected by an outdoor security camera are much less likely to be broken into. A wireless outdoor security camera is built tougher than just any camera and the wireless technology allows the owner to install the camera anywhere within range of a wireless signal. With that in mind there are a few major points that must be considered when looking to buy a camera. The exact specification you are looking for depends on what you need. But these three points will help make sure that you have surveyed the area to be monitored and defined your needs which are the first step to shopping for the right camera. Here we are going to assume that you have already determined the conditions under which the camera must perform.

Wireless Range

The specification particular to a wireless camera is the range. What is the distance the camera can be positioned from the transmitter before the signal becomes too weak for the two devices to connect. Ideally there is a clear line of sight between the transmitter and receiver for optimal range. Also, wireless devices use radio frequencies that might interfere with one another so if there is more than one camera in the area be sure the check the frequencies that they operate at to avoid any interference. Map out the mounting locations of every camera not only to get the best picture but also to be sure that the connection between the camera and other security devices are connected.


Since these cameras will be installed outdoors they will be required to meet a standard of durability to stand up against weather and other factors posed by the outdoor conditions. An outdoor security camera in Arizona will require different resistance than a camera in Minnesota. Before buying a camera you need to know whether it will be able to stand up to wind, dust, rain, snow or ice and what the conditions are where the camera will be installed. It is also a good idea to check the terms of the warranty closely. Weather is not the only challenge outdoor cameras will face. Some areas are high risk of vandalism and you might need a special camera housing to withstand physical attacks. Whatever the conditions are, just be sure you have the camera to match.

Night Vision

Usually during the night is when most unwanted activity is likely to occur. For that reason most security is geared toward protecting at night. What is important with a security camera is how well the camera can capture useful video footage in low light conditions. Dark images are useless so you need a camera that has some kind of night vision technology that allows for low light use. Or, if the situation warrants, you could just use additional lighting to the area. This depends on where you are installing the camera and how it is being used. Just avoid buying a camera that absolutely needs bright clear days to capture any useful images when you know you will need the camera for night use.

Everyone looking to buy anything will always take the lower priced product into consideration and that is perfectly fine so long as that is not the only criteria by which you are shopping. The camera has to meet your minimum standards and be able to fulfill its job or it is virtually useless if it cannot record in the dark as you intended or it is damaged by a little rain. Buy a high quality wireless outdoor security camera that is right for the conditions and it will protect your home and property for many years to come.
