How can small businesses benefit from having a security camera system business grade installed into their office location? Especially if you work in a remote location or a small town, why should you even bother with security cameras? We humbly submit that every business owner would benefit from 24-hour surveillance to protect from those on the inside and those on the outside. Taking the time to put in cameras in the right PUBLIC locations and informing your employees that 24-hour monitoring will protect the business can provide incredible ROI, even if it’s not in directly financial ways. From helping you to observe and terminate relationships with employees who aren’t being honest in their work, to protecting you from customers who might make false accusations, you’ll see the benefits. But of course cameras can’t actually do all the work on their own, there’s a whole system that’s required to make surveillance work properly. In this article we will talk about DVR systems, and how to select the right one for your business.
Digital Video Recorders (DVRs) are computers that have been built and programmed to accomplish three very specific tasks:
- Provide live display from surveillance cameras to a monitor.
- Provide quality recordings of the footage displayed live that are available for review at a later time.
- Provide remote access to those parties interested in monitoring.
There are options for stand-alone digital recorders and PC based recorders, which can be either solely for the purpose of surveillance, or can share space on your personal computer. It is important for business owners to select the machine that will properly drive a reliable surveillance program for 24-hour care.
When deciding between stand alone DVRs and PC based DVRs here are some of considerations that should be had. Standalone systems are built with the parts for running the programs and the parts for storing the footage and nothing more. These systems are incredibly reliable, they are more difficult to hack and less likely to get a virus, and they use hardware to perform the tasks needed, not software. PC based DVRs are run by programs that perform compression and operation. These systems are much more liquid and vulnerable to hackers and Internet viruses, but they are also more compatible with programs that some security systems want, i.e. facial ID and license plate recognition. Both have their strengths. Stand alone systems tend to be cheaper unless you’re using a simple application on your OWN PC, which is not advisable.
It is important when considering which DVR you will purchase for your system that you consider the resolution that the system not only displays with, but RECORDS with. Because these are two separate functions the display quality can vary during the process. While a camera might record at 720p, the DVR might only record the footage at 360×240. This means you will lose a high portion of the useful information provided in the original image. Of course systems that record with full resolution require MUCH MORE space. There are systems out there though that can display and record at 1080p! They utilize high quality compression systems and A LOT of storage to accomplish this task.
After the footage has been displayed the first time the machine must quickly set about storing it away. Compression means that the system is going to carefully analyze each frame of footage and determine which frames have redundant information. Then discarding the redundancies the rest is saved. While less compression can mean that you will get a better image it requires more space to be saved. The best compression on the market these days is H.264 as it saves a high-resolution image but takes less space.
Getting the right DVR system for your business will ensure that you’re surveillance system is running properly and that in the case of an event, whether burglary or business disagreement, you’ll have the information you need!
