I started in the professional surveillance camera industry years before DIY was a mainstream thing. Yes, way before Nest Cam, Ring, Arlo, and the hundreds of new consumer-based camera brands were even on the market. Now, commercial facilities and even local governments traditionally have much higher standards for professional security camera systems than something you would buy in retail settings like Walmart or Home Depot. The problem lies in a ton of misinformation online, and consumer-based DIY camera kits are often marketed to commercial facilities as “professional solutions.” This simple guide can give you actionable information to arm yourself in your next video surveillance system’s buying process.
Security Camera Specifications:
Security cameras for the consumer market have smaller sensor sizes, such as a quarter-inch and fixed focal board mount lenses that range from 2 to 4 millimeters. These will give you a wide-angle (which can be a good thing), but it’s grainy when you digitally zoom into the image, even though it is a “high-definition camera.” In these situations, the pixels are spread out over a wide field of view, reducing the amount of forensic quality you can achieve. For example, if the camera is mounted 12 feet high on a wall and the subject is 10 to 15 feet away, there’s a genuine possibility that you will not be able to identify the issue. Most DIY consumer-based cameras look great in marketing because they are mounted four feet up on a wall, with the subject standing a foot away. This is not always the ideal camera location for commercial applications.
A professional video surveillance camera should have a varifocal lens or, what is most common now, an autofocus lens that allows the user to optically zoom in at a specific target or zoom out for a wide view. This comes in handy over time because you won’t have to climb a ladder to change your camera’s focal length. These professional cameras come prepared for a variety of applications that can deliver forensic detail or situational awareness.
Professional security camera installers use 360-degree, fisheye cameras with a multi-sensor feature depending on the business needs and requirements. Fisheye cameras use a fisheye lens that supports 180-degree monitoring with High Definition video quality. A single fisheye security camera can cover up to 4,000 square feet and replace many regular cameras without any loss in coverage. You will just need to run one cable for a fisheye camera as compared to the multiple cables required for standard cameras.
Limited Video Surveillance Storage
Professional security camera systems require storage that is secure and redundant. A commercial storage server for video surveillance should not be an embedded operating system and should have some kind of storage that is RAID-protected. There should be a solid-state drive on the operating system as well. Storage consumption can vary, but most users follow the standard of keeping 30 days of recording based on motion activity, which can have a pre-and post-buffer to make sure nothing is missed. The entire context of the situation is recorded.
Consumer camera systems can store videos in the cloud. This is an excellent capability in theory, but the cost can ramp up depending on the resolution you set. Yes, even if it’s an HD camera, that doesn’t mean you can store HD recordings in the cloud at an economical rate. Overall, the higher the resolution and the greater the number of cameras, the more your cloud storage costs. Furthermore, out-of-the-box features usually limit recordings to 10-second clips, which are not very useful by commercial standards. This is an area of focus in the professional surveillance camera industry. There is hope for commercial cloud video surveillance or “VSaaS” (Video Surveillance as a Service). Between image quality limitations, intelligent video, and overall evidence management, there are too many limitations for us to recommend these platforms to our commercial clients who require mission-critical surveillance systems.
Another problem with these consumer systems masquerading as professional video surveillance kits is that they are supplied, more often than not, with a low-cost, low-quality Linux system that doesn’t work reliably with hard drives made for video surveillance. Finally, the embedded DVR systems typically have a set amount of storage. If you add cameras in the future, these systems may not allow you to simply add another hard disk drive and instead require you to purchase an entirely new system.
All you have to do is a simple Google search: “Nest Cam Cyber Hack.” You will see dozens of user complaints and downright scary stories, from cameras not being set up properly on networks to direct infiltration and cyber attackers using a camera’s speaker function to speak directly to the end-user. Even the professional security camera market has had plenty of issues in this area, with the U.S. recently passing a law banning the use of equipment made by one of the world’s largest security camera manufacturers for securing government facilities, critical infrastructure, and other applications with national security implications. This not only means they can’t be used going forward, but it also means that these cameras and other equipment have to be removed from operation completely.
Another problem that’s not talked about enough; the same companies with these significant cyber vulnerabilities are the same brands with hundreds of OEM (original equipment manufacturer) partnerships, which enables companies to put their labels on the cameras, disguising the original manufacturer. Most industry security professionals have private lists which they can share with you to check if your system or proposed system is on this “blacklist.”
Proprietary Security Camera Systems
If a lower total cost of ownership is the long-term goal, going with a proprietary system is the biggest mistake of all. The consumer-based DIY market is filled with systems where the camera only works with one video management software and vice versa. If a camera goes down or is at the end of its life, you would have to go back to the same manufacturer and get the same camera brand (assuming they are still in business). Furthermore, you need to trust that the camera they provide is best for every camera location you need it for. The beauty of an open-platform professional video management system is that it can work with hundreds, if not thousands, of surveillance camera brands, and you can have the best camera for specific applications.
Besides, open-source systems allow users to integrate with other security technology, such as access control systems, video analytics, mass notification systems, and more. Fundamentally, starting with an open-platform system will allow you to grow your network over time, ensure the best performance, and deliver best-in-breed components for your system.
- Things to Avoid with Professional Security Camera Systems: 20% 20%
Here is your final checklist of things to avoid if you want a professional video surveillance system and don’t want to be fooled by a polished DIY consumer system:
Avoid fixed focal board mount lenses for all camera locations
Avoid smaller sensor sizes
Avoid embedded DVR systems
Avoid brands with known cyber vulnerabilities
Avoid proprietary software and systems
In conclusion, if you have a commercial facility, get the opinion of an industry professional who can deliver several options and a complete video surveillance system to save you time. An on-site walk-through is generally the best approach to put your situation into context with expertise.
