There are several different types of CCTV (Closed Circuit TeleVision) power supplies. Currently in the digital video security industry there are two basic types of power that are used; 1.) 24 Vac and 2.) 12 v DC. Most digital video cameras utilize a low-voltage power supply so there are not as many potentially dangerous factors to be concerned about as there is if they used full household Alternating Current (AC).

Personal Protection Devices
Thursday, August 4th, 2011
If you are concerned about your own security, you may be looking for personal protection devices to keep you safe and sound. Many people today commute to work on public transportation or work a late shift when most other people are home. This creates an atmosphere that is prime for an assailant that is interested in steeling your personal belongings or worse, personally injuring you.
What can be done to prevent such atrocity? While it may not be possible to prevent the ill intent of all individuals looking to make their situation better from the illegally acquired resources of someone else, personal protection devices can prevent an assailant’s attack; some can even temporarily (and harmlessly) immobilize the assailant until authorities arrive for help.
Coax Surge Protection
Wednesday, June 15th, 2011
Although the cable used for digital video security systems does not carry a high voltage charge, coax surge protection is still required to protect your system from lightening and even overzealous power outages, and power surges. If a surge makes its way to the camera or to the DVR your system could be destroyed.
While power outages and other non-lightening power surges are highly irregular for digital video security camera systems, coax surge protection is needed much more often, especially if you have outdoor cameras that could be a target for a random lightening bolt hit.
School Security Systems

These days school security systems consist of a little bit more than just a truant officer of the 1970′s and before. Thanks to always evolving technology and reduced prices, a digital video security camera system usually plays a big part in school security systems as well as maintaining order within the classroom.
Many schools have gone to total digital video with a camera with audio in every room. This provides superior documentation in the event of a student disturbance. Likewise, the “camera in every room” policy can not only protect teachers but can protect students as well especially by documenting teacher-student situations as they occur.
