Hikvision’s DS-K1T341A Series Face Recognition Terminal has arrived at SEN for testing. First impressions are positive – typical Hikvision quality build with good hand feel and a sleek finish all over, a solid working temperature range, backed up with an IP65 rating against dust and water.

Probably the key takeaway is the simplicity of operation and installation with this terminal – it handles a database of 1500 cards, 1500 faces and 1500 fingerprints and 150,000 events, it does so in the easiest possible way, with clear audio feedback of authentication attempts.

Installation is a snap, too, with single clearly marked bundles of wires handling RS-485, Weigand and the typical 7-wire strike loom. There’s a USB port underneath to access data and a quality 4.3-inch 720p LCD screen. A ridged body helps disperse accumulated heat.

There’s 2-way audio with client software, indoor station, and master station, supports for TCP/IP, support for ISUP5.0, ISAPI, configuration via the web client, face recognition with an authentication distance of 0.5m to 1.5m, though our preliminary twiddling suggests it works well at closer ranges, too.

The integrated camera is 2MP with a wide-angle lens and the terminal is claimed to deliver fast reads from its deep learning algorithm, which makes it more accurate over time when identifying a user. Read time is said to 0.2 second and we think it’s slightly faster than this, while face accuracy is claimed to be 99 per cent.

Something interesting is that it requires a lot of work to trick the deep learning algorithm. It’s capable of seeing through silly faces, medical masks and it even identifies me accurately when half obscured by a DSLR camera and reminds me to put on a mask. I’d say accuracy is higher than 99 per cent when there are no obstructions and lower than 99 per cent in the presence of obstructions. Regardless, performance is very good.
