Often the question comes up of why not record at a higher resolution that 1080p? 4K is available – why not use that resolution instead? There are increasingly higher and higher resolutions out there that get more and more specialist.
1080p resolution is 2MP. There are 3MP, 5MP, 8MP, 10MP, 12MP security cameras and so on on the market. Here at Orange Security we feel these are overkill and not necessary and here are the reasons why:
There are 3 elements that influence the cost. The first is the cost of the cameras – generally for a given quality, the higher the resolution of the cameras, the more expensive they are. The second is the cost of the recorders – again, the higher the resolution they can store in, the more expensive they are. The third is that the higher the resolution being recorded, the more hard drive space that is required hence the increased cost.
Once higher resolutions are introduced into a security camera system, complications occur – for example, either in terms of the speed of networks (if IP) or quality of cabling and connections (if not).
3. Future proof
There are many weird and wonderful higher and higher resolutions regularly launched that are just not an industry standard. If you base your system around a resolution that is not industry standard in the future if something goes wrong, it’s likely you won’t be able to find something to buy to slot into your system. This is a similar issue as described in our Camera Connections article.
You will see security camera systems advertised that offer high megapixels, with a small amount of hard drive space and that can record for a very long time. If it sounds too good to be true, it usually is. What you will find with these types of systems is that a 5MP camera is being recorded as a much lower resolution – 1080p and often even lower than that! Not only do you waste money on a 5MP camera and the wiring infrastructure to support it, but you then also find the recorded quality is much worse than that of a cheaper setup!
