If you're on a lower budget and need a security system for a small home installation, (or something of the like) we also have an option for you to purchase an AHD (Analog High Definition) system. These AHD systems do not derive from any market leader but do offer exceptional HD quality for the price while sacrificing some features that HD-TVI and HD-CVI hold. You can purchase these systems 'as is' and from our 'Home' category with a fixed buy it now price (no quote needed). They are suited for a DIY installation but a professional installer is still recommended so that it's done properly and in some circumstances (if you're renting) your landlord may require it professionally installed.
Our AHD systems usually come with manufacturer standard HD coaxial cables (which do the job) but can also function with RG59 and others which you can purchase separately. Installers can also use the same coax cable as traditional analog cameras and they work at the same max distance which reduces hassle and labour hours.
At OverWatch Security we sell 720P, 960P & 1080P AHD solutions which become more expensive as the resolution increases, understandably. However, if you require higher resolution cameras you're going to need a higher capacity (4TB max) HDD (Hard Drive - sold separately) to store the video for long periods of time. If you require a 1080P solution and only have a 1TB hard drive it would save less than 1 week of footage. If you have a 720P solution with a 1TB hard drive you'd save over 2 weeks of footage.
Although AHD is behind HD-TVI & IP and isn't used by any industry leaders at this time, it's still a good choice if you're low on money and need something that'll do the job quick. If you're after a dedicated/top of the range solution (which you'll pay a bit more for) please refer to our HD-TVI or IP solutions.
As mentioned, AHD can reach 1080P but colours may not be as accurate and images not as crisp as TVI & IP. Transmission distance using an RG59 cable reached 1600' (the same as TVI) but drops to 492' when using a CAT5 cable.
