Apply Logic When Choosing Cameras

Apply Logic When Choosing Cameras There are so many types of security cameras, how do you know which one is right for you? Do you need a dome, bullet or standard body? Will your camera require Pan-Tilt-Zoom, Low Light, Infrared Low-Light, or License Plate technology? The most important thing you can do when buying a camera is apply logic. Here are a few tips that will help you do that and pick out the right camera to suit your needs.

1. Sketch a Floor Plan. When you sketch a floor plan, you'll want to put in all the camera locations and this will help make some key decisions. How far is your target surveillance area from your camera? Do you need a zoom lens of 4mm, 8mm or 12 mm? Maybe you need something more powerful? Maybe you need to move your camera closer?

2. Consider Field of View. Take a picture of the areas you'd like to have covered by a security camera from the proposed camera location. Do you need a wide angle or fish eye lens to cover your entire field of view?

3. Resolution & Details. How much detail do you need on your surveillance target? Are you hoping to capture the details of a face or a car license plate? The answers to these questions will help you determine, not only where to mount your camera, but the quality of the camera you choose. The more detail you need to see, the higher quality of camera you'll need to purchase.

4. Vandalism. Just like other objects you're working to protect, a security camera can be vandalized. From kids up to no good to criminals attempting to hide the camera's eyes from watching them commit their crime, to even weather and natural conditions, your cameras may need protection. If you feel this could be a problem, you'll want to consider vandal-resistant cameras and even housing to protect the camera.

5. Lighting. What is the lighting like in the area you are looking to keep an eye on? Does the lighting changed due to natural conditions? Do you need to monitor in the dark? Maybe you need infrared or low light cameras, or maybe a Wide Dynamic camera.

6. Budget. This is probably on your mind anytime you go to purchase something, but it's important to keep in mind that with security cameras, you get what you pay for, much like any other technology. But even so, having an inexpensive camera is better than nothing at all.

Security Cameras for Libraries

Security Cameras for Libraries Libraries are usually thought to be fairly docile, harmless places, but these days, no place is totally safe. People of all ages, from all walks of life take advantage of what all a library has to offer: research materials, children's activities, free internet usage, and more. One librarian can't keep watch over the entire facility but that's only one reason why library security cameras are a good idea.

Like other government buildings, libraries stand to benefit from security cameras in a number of ways. One of the main reasons is to keep patrons and staff safe from harm's way. Cameras may deter would-be criminals from committing a crime and in the event a crime does take place, police have a picture of the criminal to use in the following investigation. A second reason is to protect library materials. People have a tendency to steal from libraries and having cameras around can prevent valuable books and other materials from walking out the door without permission. Librarians, or whomever's in charge, can also monitor parts of the library when they can't physically be there to keep an eye on things.

So where should you place library security cameras? It really depends on the needs of your library. Libraries can vary greatly by size and type. You'll want to ask yourself a few questions such as "What part of the library poses the biggest security issue?" and "What type of security systems are already in place?" You'll also want to protect particularly valuable or collectible items in your library. Do you have a rare book or expensive equipment? At the library in my hometown, they often have rare displays of artifacts from around the world in the windows. Focusing cameras on items that are attractive to thieves is just plain common sense.

Placing cameras near your entrances and exits is a common sense move in any establishment. Everyone must enter and leave via these doors and therefore, everyone's face is captured. You'll also want to place cameras in common areas. Many libraries have rooms where they offer children's story hours, author visits, and even community meetings. Anyone can walk in those doors and cause a great deal of harm to library patrons, so it's important to keep cameras focused on those doors.
