The  best products and innovations for security and video surveillance In the 4k CCTV and HD security trade are now available at substantially reduced prices compared to just 12 months ago.

the latest technology includes UHD 4K resolution and thermal monitoring surveillance systems Which can be combined with analytic processing systems to create unique solutions for surveillance applications.

So what is important to know about eight megapixel 4k ?

One of the most commonly overlooked aspects of megapixel video are the lenses. Manufacturing high-quality optics for video surveillance is a difficult task which can lead to very high equipment costs. The 4000 pixel wide image of a 4K video system requires extensive design and unpresidented quality when optics are concerned. 4K CCTV cameras can be outfitted with a variety of lens options. Ranging from fixed two very focal and even optical zoom.

Many amazing developments have been released into our industry for high definition surveillance.

AHD security cameras can produce full HD images today add extremely affordable prices. AHD surveillance engineers are not working to increase that resolution to four megapixel followed by five and then eventually eight megapixel 4k.

Need a complete solution for 4K ??

Visit a trade show in your area or search for a showroom that can offer a live demo.. don’t buy a system without first testing it and viewing on your smartphone and PCs.

Jan 2018 update on unique 4K IP CAMERA models. Cortex releases a long range 5-50mm varifocal bullet for LPR applications. This model is based on the HD64 configuration and offers adjustable IR while also allowing OSD adjustments. IP cameras with 4K resolution and long range lenses are difficult to source since prices can be very high and finding the correct parts a major task.
