A few years back buying a security camera meant that you were either looking for a bullet type camera or a dome camera, but in recent days you have a staggering amount of choices and it's not just these two types of cameras anymore.
There are quite a few advanced options available in the market today, and in the following sections we will precisely discuss the three newer types of security cameras.
Pan Tilt Zoom Cameras: This type can be quite safely attributed to the best model for security surveillance. Often abbreviated as the PTZ type, this cameras can be angled to many directions and be zoomed when necessary that too remotely. They can be quite heavy because of the coverage they provide. Normally they are installed in their own bracket but sometimes the most expensive models come with rails to move freely around the coverage area. The high resolution quality keeps the images intact when zoomed. The only downside is the expense but more than makes up for it with its efficiency.
Spy Cameras: No need to be surprised over the inclusion of this type. These cameras due to their small sizes are hardly used for larger commercial areas but their contribution to security can never be belittled. Due to the small size they can be discreetly hidden inside places like home safe, cash registers, closets and other places where you might put your valuables.
Network: This is a proper surveillance system with the camera being connected to a computer for saving images for future reference.
In short, all the above systems can be very useful when comes to security. Now it is up to you to decide which model will work best for your needs.
