Damar Security Systems - Surveillance Systems

At Damar Security Systems, we strive to provide our clients with cost-effective, quality solutions and the Surveillance Systems that we offer are no exception. Our Solutions can range from replacing an analog Time-Lapse VCR with a state of the art Digital Video Recorder, to providing you with a Completely Digital Network Surveillance System that utilizes the latest in Network Technologies. Damar Security Systems can also integrate digital technology into your existing analog system that will provide your system with the building blocks to migrate from analog to digital, or we can provide you with a completely new Digital Network Surveillance System that will be scalable & flexible.

In a Completely Digital System, digital video is streamed from the cameras to the Network Video Recorder (NVR) across the network. This enables Monitoring & Recording as far away as the network reaches. Cameras on the network may be accessed individually or all cameras on the network can be accessed by connecting to the Network Video Recorder.

• High Resolution Images & Consistent Image Quality from all cameras.

• Powerful Centralized Control of the entire system – All camera configurations can be done from the Central Network Video Recorder. Pan/Tilt/Zoom, Input & Output commands are sent across the same network as the video streams.

• Ease of Installation when utilizing Wireless Technologies and Power- Over-Ethernet (PoE). Wireless technology allows cameras to be installed in locations that may be difficult to run cables to, and allows cameras to be installed at greater distances away. There are no limitations due to cable lengths. Power-Over-Ethernet (PoE) simplifies camera installations by combining the Camera Power & the Camera Data together on one cable. An additional benefit to this is Centralized Power Distribution, which simplifies the installation of Standby Power.

• Flexibility and Scalability of a Network Video System makes it Superior to existing Digital Video Recorders (DVR’s). The number of cameras that can be added to a DVR is limited. DVR’s can typically only handle 16 or 32 cameras maximum, whereas in a Network Video System, NVR’s can be linked together to appear as one, allowing an almost limitless number of cameras to be connected. In fact, cameras do not need to be installed at the same location as the NVR – as long as there is network connectivity, the cameras can be located anywhere in the world, and still be recorded on the NVR.

• Robust & Redundant Storage Options - For example, the expandability of the storage is limited. With a NVR, the amount of storage space that can be added is virtually limitless.

A Digital Network Surveillance System can also be integrated into an existing Analog CCTV system. Video Device Servers can be installed on Analog cameras to convert the analog signal, allowing the video to be streamed across a network connection to the Network Video Recorder.

New Network cameras can also be installed at this time. There are many benefits to combining an existing Analog System with a new Digital System. Utilizing the existing Analog cameras will help in keeping costs down, while installing the new Digital System will provide you with many of the benefits that exist in a completely Digital Network Surveillance System, such as flexibility and scalability.

Having a Digital System in place will also help to “Future-Proof” your Surveillance System. The Network Technologies that are utilized by the Digital Network Surveillance System are continually being advanced, and will not become “old technology”, guaranteeing the longevity of the system.

An Analog Surveillance System that utilizes a Digital Video Recorder (DVR) is an Analog System with Digital Recording. In this instance, the antiquated Time-Lapse Video Cassette Recorder (VCR) has been replaced by the Digital Video Recorder. Most DVR’s are a direct swap out for a Time-Lapse VCR & Multiplexer setup. In this case the existing analog cameras and CCTV monitor are still utilized.

A typical Analog System that consisted of more than one camera also incorporated a video multiplexer or video switcher. These devices would combine multiple video signals into one output that would go to the VCR for recording. A downfall of this is, not all multiplexers were created equal and this meant that if video was to be played back, it would need to be played back through the same make & model multiplexer. Of course this illustrates another downfall of the multiplexer/VCR setup – if video was to be played back, recording had to be stopped.

A benefit of replacing time-lapse VCR’s with a DVR is, most units can simultaneously playback recorded video, while still recording. Another benefit is most DVR’s have multiple camera inputs, which in effect makes the use of the multiplexer no longer necessary.

Searching for a recorded event on a DVR is much easier on a DVR than on a Time-Lapse VCR. It was a rather cumbersome task to try and locate a recorded event on a VCR. A user would have to continually fast-forward & rewind VHS tapes to try and locate the event. In a DVR, specific dates & times can be entered, and the DVR will start to play the recorded video for those specific times.
