The hardest part of starting up is starting out
¿What is a CCTV security camera?
CCTV technology has been around since the 1940’s, and became a major player in the security industry around 1970. The technology is tried and true, and there are CCTV security camera models for virtually any surveillance application. The two main categories of CCTV cameras are fixed cameras and pan/tilt/zoom models which can rotate horizontally and vertically to cover more area.
There’s a lot that goes into a typical CCTV video surveillance system. While the cameras get most of the attention in the beginning, you also have other concerns, such as viewing, recording, and archiving the video footage, and the equipment required for carrying out those tasks. Here’s a look at the basic components of a typical CCTV system.
Cameras
Security cameras are the starting point for most CCTV video surveillance systems. There are endless possibilities when choosing CCTV cameras and lenses – everything from fixed models designed for monitoring very specific locations, to day/night cameras, and powerful PTZ domes for patrolling large areas.
Monitor
In a traditional CCTV security camera setup, operators view footage from a central location on a monitor very much like a TV, but with higher lines of resolution for better picture quality. Monitors can be dedicated (meaning they display video from a single camera), or call-up (meaning operators can access multiple cameras at the same time).
Cable
With an analog system, coaxial cable is required for transmitting video footage from the CCTV security cameras. This is one of the drawbacks of analog CCTV video surveillance, as the cable can be expensive and difficult to install, especially for larger camera networks, and those were cameras must be positioned in difficult locations.
DVR
Most modern CCTV video surveillance systems incorporate DVRs (digital video recorders) which enable operators to reap some of the benefits of a network-based surveillance setup. DVRs convert the analog footage to digital, which helps to extend storage capacity, makes it much easier to search archived footage, and also allows users to stream video over a network for remote viewing from multiple locations.
CCTV Security Camera Types
Fixed CCTV surveillance cameras
Fixed security cameras point in a single direction, which makes them perfect for monitoring very specific areas of interest. They’re also preferred for applications where it’s beneficial to install cameras in clearly visible locations. For this reason, fixed CCTV surveillance cameras are quite effective not only for capturing footage of suspicious activity, but also for deterring criminals and vandals from carrying out their acts in the first place. The direction of the camera is set during installation. Many security cameras also accept interchangeable lenses and housings, so you have the flexibility to meet a wide variety of surveillance needs.
PTZ
PTZ cameras are ideal for wide-area surveillance. They give operators the ability to remotely control pan, tilt, and zoom functions to follow activity and to zoom in for detailed monitoring. This is an area where analog CCTV security cameras fall behind their IP camera counterparts. With IP cameras, the pan/tilt/zoom functions are controlled manually or automatically and delivered over a single network cable, while analog cameras require additional wiring to perform similar functionality.
LICENSE PLATE READER CAMERAS (LPR)
Dedicated LPR camera systems are high-tech systems that use a combination of high-definition cameras and special optical character recognition (OCR) to capture and identify license plates. The image is then sent to the LPR camera software, which interprets the letters and numbers on the license plate and then compares them to a database or list of license plate, many of which are flagged if of interest.
Law enforcement often uses systems like this to track and locate vehicles of interest, but businesses and properties can also use them for keeping track of who enters or exits the premises. Allowed vehicles and VIPS can be checked and verified as they enter the premises, and unwanted or banned vehicles can be stopped before they attempt to enter. Administrators can create and modify the list of allowed or banned vehicles as they see fit and be alerted immediately of any flagged vehicle entering the property.
Commercial grade, dedicated security cameras with license plate readers usually come with their own proprietary OCR software. If you’re looking to use regular HD or UHD IP cameras to capture license plates, there are software available for purchase, as well as open source programs that can help.
Access Control Systems
The door access control system provides authorized individuals or companies with secure and reliable enter and exit services. Access control systems for doors can control and determine who, when, and where they can enter the appropriate area. The applications range of access control systems is from single door access control systems to large network access control systems for multiple doors buildings. It is an effective measure to solve the security management of important departments’ entrances and exits. Applicable to various confidential departments, such as office, hotel, apartment, parking lot, armory, confidential room, intelligent community, and factory. The access control system has already surpassed the simple doorway and key management, and it has gradually developed into a complete access control management system. It plays a greater role in the administrative work of work environment security and personnel attendance management.
¿What is the purpose of installing an access control system?
The most basic access control function is to block anyone or a car that should not enter an area. This can be any sensitive area of the front door, garage, office, office building, hospital, hotel etc. You may also want to use access control systems for doors to track when employees go to and from the door. Basic access control systems usually only have an access control card reader, access control power supply, and maglock or electric bolt lock. Higher security applications may require multiple authentication methods (such as cards and fingerprints) and include more complex features. Finally, consider whether you need to integrate with other security systems, such as monitoring systems, alarm systems, and fire protection systems.
