Have IP cameras met their first real HD challenger?
Dahua, a major Chinese surveillance manufacturer approaching a billion dollars in annual revenue, is now aggressively targeting a non-IP, coax based HD offering to Western markets, they call HD-CVI.
Coax based, non-IP, HD cameras have been around years (sometimes branded as HD SDI or HDcctv) but the effort has largely failed due to a horrendous marketing effort, weak manufacturer support and uncompetitive prices.
Now, Dahua is pushing hard on HD-CVI, that claims the simplicity of analog plus analog pricing for full HD video.
We bought 3 HD cameras, including 720p [link no longer available] and 1080p [link no longer available] bullet cameras and an integrated IR PTZ [link no longer available], plus 2 HD [link no longer available] DVRs [link no longer available] all for just $1200 total - a remarkably low price for HD cameras and recorders.
We tested those cameras and recorders against comparably low price / entry level IP products.
Our test results answered the following key questions:
- Image: How did image quality compare for HD CVI vs HD IP? Day and night?
- Length: How well did HD CVI run over coax up to 1000 feet and with poor connectors?
- Latency: How much did latency differ between HD CVI and HD IP?
- PTZ: How well did PTZ controls work with HD CVI?
- Configuration: How did HD CVI camera configuration compare to HD IP?
- Value: What is the overall value and potential of HD CVI vs HD IP?
