The most important factor to capturing useful surveillance video is making sure the lighting levels are adequate for your outdoor security camera. Depending on the type and model of the camera there is a wide range when it comes to minimum lighting requirements. There are some basic strategies we can use to make sure poor lighting won’t hinder the performance of the security camera.
The first option is simple. Installing additional lighting might be the most straight forward solution to the low light conditions but it may not always be the best solution. Either the infrastructure required to install the lamps are not available or the environment requires that there are no lights, such as surveillance of a dark room. Also, the controls for the light are another consideration with this strategy. Leaving the lights on 24 hours can be costly but turning the lights on and off could require additional hardware, such as light sensors. Sometimes additional lighting is not sufficient for the conditions, whatever the case there are two other options.
If the area is not completely dark and the light levels are just too low, try a black and white camera. Colored cameras have higher light requirements than black and white cameras and for that reason a black and white camera can capture images at much lower light levels than a colored camera. This is only effective if there is still some light in the area to be under surveillance. Otherwise a night vision camera will be required.
Night vision security cameras come in varying degrees of effectiveness measured by the LUX rating of the camera. The LUX rating lets us know the minimum light levels required for the security camera to work. The infrared technology records light at a frequency beyond what is visible to our eyes and produces the image in shades of green. The LUX rating is only useful when comparing between similar manufacturers because it is relative to their standards. By itself it doesn’t tell us much except that a LUX rating of 0 means the camera can produce an image in complete darkness.
The sole purpose of an outdoor security camera is to record activity in an area for increased security and darkness is more reason to increase the level of security. Psychologically people feel more secure committing crimes under the cover darkness and that is why we have a need to protect our things, our families, and ourselves with security surveillance cameras.
The best way to protect an outdoor security camera is by using common sense and taking as many threats into consideration before installing the camera. This way you can look for the optimal installation position and strategy to minimize the chances of damage to your camera. Don’t forget all the supporting accessories in your security surveillance system such as the cables that connect the hardware. They need to be protected just like the rest of the system.

The purpose of an outdoor security camera is to monitor an area that is prone to criminal activity or otherwise undesired activity. For this reason the camera itself is put at risk of physical destruction from the very vandals we are protecting ourselves from. There are, however, a few things we can control to minimize the risks.
We must take into consideration the design of the camera or the housing the camera will be encased in. Then how the camera is mounted, where it is mounted, and the very placement of the camera are factors that will determine the amount of risk the camera is in. We can also use intelligent video alarms to deter vandals.
When it comes to the housing or casing of a camera, one made of metal is better protection against vandalism than something made of plastic. Also, a boxy traditional camera that sticks out of a wall or ceiling is much more susceptible to being damaged than a dome shaped encasement. It helps to be hidden and disguised as part of the environment, since the chance of being recognized is minimized.
How the camera is mounted also will determine the level of protection from physical abuse. Mounting the camera or housing flush with a wall or ceiling is much more effective than simply mounting it on the wall or ceiling. If most of the camera is mounted inside with only the transparent part showing, it is much better protected from different angles. We also want the cables to be pulled directly through the wall or ceiling but if that can’t be then at least run the cables through a metal conduit tube to protect the cables.
The placement of the camera is a big factor in deterring vandals. If the camera is placed high on a wall or ceiling it will eliminate the on-the-spot vandals. Vandalizing a camera out of normal reach requires some contemplation and that is enough to deter the non-serious vandals. The only trouble might be the effect of desired viewing angles.
Installing alarms is a more costly but very effective measure. It can alert operators if there is some level of tampering on the camera. This prevents redirection or obscured viewing from going unnoticed. Active tampering alarm features are very useful in a large installation with many cameras and keeping track to make sure all the cameras are working properly can get complicated. This way someone will be alerted if one of your outdoor security cameras aren’t working as it should.

Our cities are becoming more frightening and we need to devote more attention to basic security. Common sense protects more than your home and home security is also about keeping people safe. Good home security is about how you think. Do you ever forget to lock up? Do you usually forget to lock the garage? Does your house offer lots of hiding places like shrubs, beside doorways and lower windows? When you’re away, does your house seem deserted? Do trusted family members know where to locate you if necessary? Once you can master these simple basics, you can look at different products.
Home alarms have been in use for many years and have evolved in with every passing year. There are systems with or without monthly monitoring or ones that will call you on your cell. Many systems have wireless components so that you can rearrange them when you decide to and they’re simple enough to install quickly and without any expensive help. The old fashioned rigid one-size for everything security systems are truly a thing of the past.
Security lighting is the foundation of many good systems. It’s quite irreplaceable. A brilliantly illuminated home has a first line of defense against vandals and it’s hardly the ideal environment for people who are doing things they don’t want others to see. Lighting also helps you arrive safely home, showing you places like darkened paths to be certain that it’s safe to move around.
It’s great to notice the abundant commitment to solar powered security systems. It means we can be green and cut our spending while we’re at it. On top of that these systems are really are easy to set up and delightfully affordable. All the pieces in one place and you won’t need an electrician.
Remotely controlled security cameras take home security to a new place. Imagine that you’re lounging comfortably and very safely in your upstairs and controlling cameras strategically situated around you entrances. You can see everything. Nursery cameras with conveniently small monitors, with sight and sound and remote control cameras mean you never need to worry about what might be happening in the nursery, again. Many of the remote controlled products can be monitored though the net. Now, worried parents of party loving teenagers control the party.
Do you recall the original nursery monitors? Nursery systems are much better now. They cover the ground from the basic audio monitors to very complex hidden cameras. Everyone has heard of options like the Nanny Cams, but you’d be quite surprised at all the places they might be hidden.
Hidden cameras have evolved considerably from the original boxy versions that were wildly expensive and took terrible images on top of that. Today’s hidden cameras are small and have lots of different features. You can have hard wired or wireless, colored or black & white and a growing number can even pick out an image in almost total darkness. What you won’t find audio recording- that’s illegal.
