Spy Tec STI Z16 Review

Online you can find hundreds of different surveillance cameras. Some of them are very expensive (the professional ones) while others are very affordable. Today I will review a popular surveillance camera called Spy Tec STI_Z16 – Zetta Z16. Here are my impressions :

Video Quality

The Spy Tec STI_Z16 surveillance camera records in 720P. That’s not Full HD of course, but you have to understand that the better video quality you want, the more you will have to pay. For most consumers (in my opinion obviously) – 720P resolution is enough. 8 years ago a camera like this would cost at least 5 times as much. Spy Tec STI_Z16 also features wide angle lens (very important). The video quality is really not disappointing. It is important to mention that the company also sells a model called Spy Tec STI_ZIR32 (Amazon link). In my opinion it is better (provides much longer recording time).

The Spy Zetta Z16 camera supports MicroSD memory cards up to 64GB. Most cheap surveillance cameras will only support 32GB cards by the way. 64GB is plenty of space, more than enough. You will have to buy the MicroSD memory card separately of course. There is no need whatsoever to buy a fancy and expensive one – just buy a basic Sandisk memory card. It should not cost too much, and there are so many places online you can buy it from.


The battery life of this camera is really good – up to 10 hours (or 4 month of standby). The device is fairly small so 10 hours are excellent. You can charge the camera every night in case you use it daily. The Spy Tec STI_ZIR32 (Amazon link) model I mentioned earlier provides up to 24 hours (in reality – at bit less) of continuous recording time, but it is bigger and more noticeable. If you really need the best battery life – I recommend buying the second model of course.


The STI_Z16 camera has different sensors like motion detector and voice detector. That means you don’t really have to push the “recording button” and waste the srotage space on useless footage. You can set the camera to detect motion, voice or even vibrations, and it will start recording automatically. Very useful, and will also extend the battery time of course. Not all cameras in this price range come with these features. The motion detection option works fairly well actually, I think it is super useful.

Value For Money

If you can’t afford buying a professional surveillance camera, a device like Spy Tec STI_Z16 will be perfect for you. The video quality it provides is good, and overall it works really well. In my opinion it is a great camera worth buying.
