Cameras have their roots in the 1880\u2019s motion picture business, but closed-circuit television (CCTV) cameras weren\u2019t used for surveillance until the middle of the Second World War when Germans used them to monitor the launch of V2 rockets. <\/p>\n\n\n\n

The technology would become commercially available not long after, and largely used by governments, banks, and retail operations. But camera choices were limited. For years, it was analog or analog, as the first internet protocol (IP) camera wasn\u2019t released until the mid-1990s. <\/p>\n\n\n\n

Fast forward just a few short decades to today, and powerful surveillance camera options<\/a> are seemingly endless. Furthermore, the parity of analog, IP, and HD over Coax cameras has made leaps and bounds. I probably have 25 consultations a day with customers grappling with what cameras to use for their video surveillance system. These are good issues to have, because it means customers have a lot of strong options, but it can be confusing. So, how do you know what cameras are the most suitable for your video surveillance system deployment? There are pros and cons to each, and the answer depends largely on your needs. Let\u2019s take a closer look \u2026\u00a0<\/p>\n\n\n\n

Analog Cameras<\/h3>\n\n\n\n

Analog cameras capture video and transfer it directly to a digital video recorder (DVR) through a coaxial cable. <\/strong><\/p>\n\n\n\n

Pros<\/strong><\/p>\n\n\n\n

Ease of migrating solution to the cloud \u2013 A vast majority of existing installations today are analog. To sync a new system to the cloud, it\u2019s as simple as installing a bridge or cloud managed video recorder (CMVR)<\/a> and plugging it in. You keep a majority of cameras and cables, and replace just one device. For the reseller, it\u2019s instant recurring monthly revenue, and for the end user, it preserves the existing investment, and consequently, saves money.<\/p>\n\n\n\n

All the benefits of the cloud \u2013 Once your analog camera is connected to the cloud, you garner all the high-end enterprise level features fundamentally baked into the product at a very affordable price, including centralization, redundancy, availability, and so on.<\/p>\n\n\n\n

Supports long cable distances \u2013 Analog is ideal for long cable distances needed in areas such as parking lots, schools, and campus-style businesses. Most or all of this can be preserved when you migrate to the cloud.<\/p>\n\n\n\n

Full frame rate with no compression \u2013 Analog inherently runs at full frame rate with no compression, ensuring your video looks really smooth. This is particularly helpful in environments such as casinos, where you need to review everything on a per-frame basis to capture fast action.  <\/p>\n\n\n\n

Cons<\/strong><\/p>\n\n\n\n

Resolution limitations \u2013 There\u2019s a theoretical maximum resolution for analog cameras, which is\u00a0a fraction of today’s IP camera capabilities. To compare, some IP cameras can have up to 32 times the resolution.<\/p>\n\n\n\n

The industry is losing senior techs who know how to diagnose and repair analog cameras \u2013 Newer technicians are more network savvy, but they don\u2019t necessarily have experience servicing and maintaining existing analog cameras.<\/p>\n\n\n\n

IP Cameras<\/h3>\n\n\n\n

Commonly used for surveillance, an IP camera is a digital video camera that receives control data and sends image data via an IP network. The IP camera revolution began in the 2000s, but at the time, they were significantly more expensive, and consequently, cost-prohibitive for many businesses. Today, you can still get expensive, high-end IP cameras with insane bells and whistles, but you can also find plenty of options on par, pricewise, with the analog cameras of yesteryear. <\/p>\n\n\n\n

Pros <\/strong><\/p>\n\n\n\n

Resolution \u2013 Modern IP cameras have excellent image quality and resolution. And because the amount of pixels on target is so much better, you gain the ability to gather forensic details easier, such as people\u2019s faces, license plate numbers, etc.<\/p>\n\n\n\n

Specialized cameras \u2013 IP cameras provide the best breadth of application in the market. IP cameras can be multi-image, fisheye, thermal, bullet, dome, and more.  <\/p>\n\n\n\n

Cons<\/strong><\/p>\n\n\n\n

Technicians have to learn networking \u2013 There is an entire generation of technical people whose core competency centers around analog. Suddenly, their capabilities are being upended and they\u2019re having to learn networking. This is particularly tough for some of the giants that employed thousands of techs.  <\/p>\n\n\n\n

You lose a little of the low-latency experience \u2013 An aspect of networking is the data is flowing in all different directions as devices are communicating. There is a limit to how quickly this data can be prioritized and transferred, and this creates latency. With IP, you can expect one to two seconds of latency. That\u2019s completely acceptable; however, analog is basically instantaneous. And the latency is exacerbated by remote viewing.<\/p>\n\n\n\n

Dedicated network recommended \u2013 Video data is the densest form of data that will flow through any network, and can cause havoc on an existing network, taking it over so that no other data can move through. It’s recommended you create a dedicated network for the IP camera, so as not to interfere with existing networks that are used for business purposes. This has an inherent cost associated with it in the form of extra hardware.<\/p>\n\n\n\n

Some IP cameras are really expensive \u2013 You could spend upwards of $45,000 on a specialized IP camera with features such as thermal, night vision, positioning systems, etc.  <\/p>\n\n\n\n

HD over Coax Cameras<\/h3>\n\n\n\n

HD over Coax cameras offer real-time uncompressed (or very slightly compressed) video data direct from the camera to the recorder. 2014 was the pivot point during which HD over Coax started to become a thing, because suddenly you were able to push megapixel resolution images through Coax, where previously you had a limit. <\/p>\n\n\n\n

Pros<\/strong><\/p>\n\n\n\n

You can preserve your Coax infrastructure \u2013 With HD over Coax you don\u2019t have to rip and replace existing cable, which can be very costly … even more so than starting from scratch. You can just replace the camera and recording devices at either end of the cable and you essentially have a brand new system.<\/p>\n\n\n\n

You\u2019re getting all the best of both technologies \u2013 HD over Coax provides you with high-resolution video and great image quality that\u2019s very cost effective.  <\/p>\n\n\n\n

Makes installers very competitive \u2013 Price is king, and this approach is way less expensive for the end-user.  <\/p>\n\n\n\n

Cons<\/strong><\/p>\n\n\n\n

Limited amount of camera types \u2013 With HD over Coax, you don\u2019t have the breadth of products, like dome, bullet, and other popular form-factor cameras that you do with IP.<\/p>\n\n\n\n

Cable issues \u2013 You have to have copper core cabling. HD over Coax won\u2019t work with copper clad. And, it takes tribal knowledge to know which you have. The tech needs to know to go to the cable, snip off the connector, and check the cable type.<\/p>\n","protected":false},"excerpt":{"rendered":"
