What Types Of Security Cameras Are There?

Small CCTV CameraSecurity cameras can be divided into 3 broad categories:

1) Wired CCTV Cameras, and
2) Wireless CCTV Cameras

Wired cameras are exactly that. Attached or connected to a hard drive & screen monitors by a solid cable. They record to a computer hard drive, and require extensive installation.

Wireless cameras have no wires or restrictions, and can record to hard drives as well, however the installation is far easier.

Under each of these broad categories there are several different camera types.

Wired Cameras Include:

Covert Surveillance Cameras – these are the ones that can imitate small objects like “regular household items such as a hole on an alarm clock or buttons on a doll. They are so small that they are virtually undetectable. Typically the footage from these cameras is relatively low quality.

Fixed CCTV Cameras – These cameras are “fixed” in one position, generally used in locations where “pan” and “zoom” are unnecessary – such as front doors, or near a secure gate. These cameras are typically a “bullet” shape (when inside or sheltered) or encased in the larger white protective housing/case that is commonly associated with an out door security camera.

Motorized CCTV Cameras – These cameras can be moved remotely enabling the end user to pan and zoom the camera to get a close up look at an object. They can also be moved in any direction to follow or track anything in the field of view.

Both internal and external versions of wired security cameras can be in a “dome” shape. The clear plastic coatings of these cameras can even be “vandal proof” to prevent individuals from spraying paint on them, thereby preventing the camera from becoming occluded.

There are larger external cameras (the type you see on roadways or major commercial buildings) that have an incredible ability to zoom into a distant object, even at low light or at night.

Wireless Cameras Include:

Simple Cameras – connected to a wireless base station. The cameras can have LED light illumination allowing viewing in complete darkness. These require connection to a local “WIFI” network – so while they lose the need for cables, they don’t allow 100% “true” wireless capability. These can be great for “spy” type cameras.

Videofied Wireless – “Videofied” is a wireless security camera system that is also a wireless alarm system. They only record when they are activated, virtually eliminating “false alarms”, and guaranteeing a police response (something that was previously only possible with 24/7 monitored security cameras).

So what type of security camera is right for you?

This is dependant on your budget & requirements.

If you want better image quality & don’t need wireless – look at a wired system. If you want true portability – look at wireless systems.
