Today, digital security cameras are increasingly used in our society, homes and offices. Small in size and easier to install, they give sharper images.

Different models of digital security cameras are available in the market. They include wireless digital security cameras, color digital pen-type mini cameras, security system with indoor and outdoor cameras, security first fas-1248, pelco digital security cameras, and e-mobile-cameras. 

Wireless digital cameras are smaller, light weight and professional quality devices. They have higher sensitivity and saturation signal. They are powerful and easy to install and operate. Color digital pen-type mini cameras have multifunction software, USB cable, tripod and AAA batteries. 

Security first fas-1248 cameras have 14 inch black and white monitor with built-in real-time quad processor. Pelco digital security cameras have a compact body style. They have digital signal processing and auto white balance. E-mobile-cameras are digital security camera systems for vehicle, retail or secret use. 

They store up to 32 digital images. Their typical applications include installation in vehicles such as taxi's, delivery vans, ambulances, police cars or use in small shops and restaurants.

Black and white security cameras are inexpensive cameras that work well in high and low light conditions. Color security cameras are also inexpensive but they work only in general working light. Covert security cameras are so small that they cannot be easily seen. 

They can be concealed as a different device (such as smoke detector, clock or teddy bear). Day/night security cameras switch from color to black and white depending on lighting levels. They are ideal for variable lighting conditions. 

High-resolution security cameras have extra light sensors on their digital chips. They increase the effective image quality. These cameras are effective only with high-resolution monitors. Infrared security cameras have their own light source in a light spectrum that can't be seen by the naked eye. 

These cameras are good for small areas with no light. Outdoor security cameras have hardened, waterproof outer bodies. Vandal proof security cameras come in hardened cases that can resist the toughest physical abuse.
