Digital Video Recorders and Network Video Recorders

Access Security Corporation engineers surveillance systems that utilize digital video recorders (DVR) and network video recorders (NVR). These recorders document the visual input from the security cameras. They support the security and administration staff by providing high-resolution documentation of video events. The DVRs and NVRs can selectively record video from cameras according to alarm activity, movement, user command, or they can record continuous video. Digital video recorders record the cameras over conventional coaxial cable home run to the DVR. Network video recorders are linked to IP cameras through a shared or dedicated local area network (LAN). Hybrid recorders, a combination of DVRs and NVRs, are also frequently used. These Hybrid recorders allow you to use existing CCTV cameras while still allowing the use of IP cameras.

Digital Video Recorder (DVR) and the CCTV Surveillance Systems
Access Security Corporation utilizes digital video recorders as an essential part of the CCTV surveillance system. By recording the video signals of the CCTV security cameras, digital video recorders are capable of selectively recording activity from multiple areas of a facility. Furthermore, digital video recorders can be set to record when motion is detected or when an alarm occurs. At that point they systematically document movement or intrusion. When the alarm is triggered, the digital video recorder is capable of documenting all video from up to sixty seconds before and/or after the incident actually occurred. The video is “tagged” and the action of any person who enters the facility is recorded for later viewing. Digital video recorders that are incorporated with an access control system or an alarm system also provide a higher level of security for a company. Archived video is easily retrieved for review, by security or administrative staff. This selective recording feature decreases the time required to search for events and increases the efficiency of the entire security system.

Access Security utilizes digital video recorders which can be desktop or rack mounted. DVR system sizes range from as few as 4 cameras to as many as a few hundred. We provide the expert services that carefully assess the security needs of your company as well as your facility in order to engineer the best possible surveillance system.

Network Video Recorder (NVR) for CCTV Surveillance
The network video recorder is used when a network or Ethernet solution is required. This equipment is a comprehensive recording device for IP security cameras. Connected to a shared or dedicated network, the video recorder captures the video from the IP cameras. These NVRs allow companies to use existing infrastructure to implement a security surveillance system. These network video recorders also provide your company with more flexibility and expandability in its surveillance options as future needs arise.
