Here at Harmony Technologies we have fitted a range of CCTV systems from different suppliers but none have surpassed expectations as well as DDS. Their friendly and helpful staff are always on hand to offer advice. Their aftercare is also the best around. Just like to say a massive thank you to sales and tech support, Keep up the great work. Harmony Technologies will be dealing with DDS for the foreseeable future.
