“A diverse security apparatus is a strong security apparatusâ€
-Joseph Wolff, CTO, eRacks
Hence, we are offering three variants of surveillance systems
- eRacks/HVR (Hybrid Video Recorder)
- eRacks/NVR (Network Video Recorder)
- eRacks/DVR (Digital Video Recorder)
Each of the technology we are offering to our valuable clients are discussed in detail below
- eRacks/HVR (Hybrid Video Recorder)
eRacks/HVR (Hybrid Video Recorder) is quickly growing in popularity because of its versatility. Hybrid video recorders (eRacks/HVR) are compatible with both standard analog signal and IP network cameras, allowing the users to continue using their current installed analog security system while gradually shifting to the latest network IP technology. It grants the flexibility to upgrade the existing surveillance system to IP equipment according to the user’s budget and specifications.
A hybrid system integrates existing analog cameras into an IP network, providing the user with all the advantages of an IP system excluding the HD resolution of IP cameras. In a hybrid CCTV system, footage is recorded in analogue quality however the IP network features of indexing, bookmarking, and retrieval are made available through the Hybrid eRacks/DVR.
eRacks/HVR (Hybrid Video Recorder) is best suited to record video footage in a digital format to storage array. It accommodates both IP and analog cameras and captures video/images through an Ethernet network via Cat5 / Cat6 cables from IP cameras as well as coaxial cables from analog cameras. It is mostly used for physical security applications. This option is a good choice when planning for future expansion into an IP video surveillance system as the existing analog cameras can be reused and incorporated into the system without any drop in coverage.
eRacks/HVR comes with a variety of channel counts, and storage capacities to ideally suit many applications. It also supports smart features, including event search, event log, and email notification; a free mobile app that allows users to watch live or playback video from their smartphone. Multi-site video management from anywhere in the world can be done using eRacks/HVR as well.
- eRacks/NVR (Network Video Recorder)
eRacks/NVR stands for Network Video Recorder which is a specialized hardware and software solution used in the IP video surveillance systems. This system records and store video footage directly from the network it lives on for the purpose of their storage and subsequent playback. They work with an advanced type of camera, called IP cameras. IP cameras can actually capture and process video and audio data themselves by using either an Ethernet cable or wirelessly via an existing Wi-Fi network. The eRacks/NVR does not contain any special equipment for capturing video because it receives the video streams already encoded by the IP cameras in a digital format. To support the expanded set of features and user-friendliness, the eRacks/NVR uses standard computers with standard operating systems.
eRacks/NVR systems process the video data on the camera rather than on the recorder by using IP cameras which are standalone image capturing devices. IP cameras have a chipset which processes the video data which is then transmitted to a recorder. It is capable of recording and sending audio as well as video. The more powerful hardware on IP cameras also enables improved smart functionality and video analytics, such as facial recognition. eRacks/NVR systems connect the camera to the recorder, but this is done using standard Ethernet cables, such as cat5e and cat6, to transmit data. eRacks/NVR recorders are only used for storing and viewing the footage.
eRacks/NVR systems are inherently more flexible because security cameras don’t necessarily have to be physically connected directly to the recorder. Instead, IP cameras only have to be on the same network. The video quality is also better as eRacks/NVR recorders receive a pure digital signal from the cameras. All cameras with microphones can record audio to the eRacks/NVR because Ethernet cables carry audio. eRacks/NVR systems tend to have better picture quality, as well as easier installation, are reliable, stable, provide increased flexibility, have a user-friendly interface for day-to-day use, and native support for audio on every camera that has a microphone. However, eRacks/NVR systems also tend to be quite a bit more expensive which is a huge constraint for budget conscious people.
- eRacks/DVR (Digital Video Recorder)
eRacks/DVR (Digital Video Recorder) has been updated for a better performance than ever. It is mostly used for physical security applications. These eRacks/DVR solutions are highly scalable and can be tailored according to the client’s needs. They can also be configured for home to enterprise class support. eRacks/DVR is a little lower priced than other available systems which makes it more attractive.
The eRacks/DVR (Digital Video Recorder) is a specialized computer system that records video in a digital format and stores it in disk drives or other mass storage devices. This updated version provides 432 TB of Surveillance Storage Drives along with optimized Digital Video recording and viewing. It normally uses analog cameras that are also called CCTV cameras, for recording. The cameras and eRacks/DVR are connected using a coaxial cable which are not very costly. Coaxial cables that were previously installed for other security systems can also be used for eRacks/DVR. This combination is more cost-effective and easier to set up; however, the resolution is usually limited to D1 (720×480). Proximity is a limitation as the analog cameras cannot be more than 700-1000 feet away from the eRacks/DVR without visible degradation in video quality.
The eRacks/DVR recorder relies on a chipset that is called AD Encoder for processing the raw data streaming from the camera into legible video recordings. eRacks/DVR systems also have different requirements when it comes to the recorder i.e., the user must connect every camera directly to the recorder. Moreover, the recorder is not responsible for providing power to the cameras. Each camera connection needs a splitter that supplies power which in turn enable cameras to function. eRacks/DVR systems can only use wired security cameras. eRacks/DVR systems also have less flexible mounting solutions because routing coaxial cable can be more difficult in tight situations and a power outlet is required for each camera. Coaxial cables don’t natively transmit an audio signal, and eRacks/DVR recorders usually have a limited number of audio input ports. eRacks/DVR Home surveillance systems are easy to set up and can be accessed through a web browser. The user is notified by email if an alarm is triggered. eRacks/DVR Server offers standard 1year full / 3year limited warranty and come with pre-configured latest Open-Source software based on the user’s specifications.

Why we Have to Say we Use Only New Components
Many of you may know this already, but:
- We build all our systems to order, and
- We only use factory fresh, new components in our new systems.
This may seem like an obvious thing to say, but it still needs to be said.
Why?
About 4-5 times a week, we get emails like the one at the end of this page –
Offering “Clean pull” components for low prices in large lots – At best, these would be considered “Refurb” components, but are really just plain used. They have a much shorter (or no) warranty period than new components – they’re also often factory seconds or grey market parts, sold sideways to dodgy suppliers so that they can build systems cheaper.
We do not use these suppliers.
So again, we always use 100% new and factory-fresh components in our new-system builds – (on occasion we sell our B-Stock systems, which are clearly marked as such, and what they are – reconditioned, etc).
Some of the additional ways it is possible to cut corners on building and assembling IT equipment, in addition to used or refurbished parts, is to use factory lot-ends, factory seconds, factory defects with a “Workaroundable” defect – this is how Dell got their start – they would buy large lots of, say, NIC cards (This was before motherboards came with them onboard!), with a known defect, and write (and pre-install) the Windows driver for it – almost always unbeknownst to the end-user, or disclaimed in fine print in the EULA that the customer is forced to accept.
In this market, with plenty of storage servers, with large numbers of 3.5″ hard disk drives, this is especially tempting for some box-builders to use components such as these – again, we do not do this, and *always* purchase new parts only, from reputable, nationally-known suppliers of components and computer parts for our servers, especially such as hard disks, etc.
We consistently see product out there in the marketplace which is built with these dodgy components, and have many times been asked by our new customers to help them bring these products up to spec with new parts, and re-test and burn-in to ensure reliability and a fighting chance at a full product lifetime.
Best,
Joe
