These are one of the best things I've found that SCK sells. I been crimping or compressing ends on for years. Which is easy, but it is expensive for the crim/compression bits from a different company I was going through for those pieces. I still HIGHLY recommend using a good compression or crimp for cameras that are exposed to weather, or have any wiring out doors. Just insures a good solid weather resistant seal. However, if it is interior cameras, or on awnings, these super easy to use connectors make installation a breeze. Like everything I've had from SCK great quality. Will be buying again, probably as soon as I submit this :).
