Camera Cable Whip Guide

By: John Scanlan, Published on Aug 03, 2018

Cable whips are one of integrator's least favorite camera features but seem to be unavoidable, now commonplace on dome, turret, and bullet cameras from low end to high.

In this report we look at the four key reasons cable whips are so disliked and how to deal with them, covering:

  • Camera whip variants
  • Whip penetration hole size
  • Excess whip length
  • Backbox requirements
  • Whip genders
  • Whips advantages
  • Manufacturer differences - Axis, Dahua, Hanwha, Hikvision, more
  • Form factor differences

When I was teaching training classes on Mobotix I would stress to techs that they would need biscuits or couplers for each camera as Mobotix provides a patch cable with the camera. The cable has a grommet that seals the camera but if you just popped on your 45 and plugged it in rather than using a coupler you had an unsealed camera

We've recently found two flooded cameras because the techs chose to not do it correctly.

Clint - Sorry to hear about the problem and thanks for sharing. We are developing more physical installation content and have planned on including content on waterproofing, which will include guidance on dealing with grommets, gaskets, silicon, drip loops, desiccant packs, and more.

John, if I may offer an installation guidance for precast concrete panels: penetrate the joints instead of going through the precast panels for exterior installations. It takes a little more time to plan how to do it based on camera mount designs and you need a mounting plate or box on the exterior, but you end up with no finished surface penetrations or obvious patches if the installed devices ever get removed. We use threaded rods as the joint penetration and lock them in place with uni-strut on the interior. Saves drill bits and makes for happy property owners.

One of the big problems now with the cameras becoming increasingly smaller is installing a cable (pre-made patch cable or self terminated RJ45) is getting it into the camera without degrading the data signal. Some I have worked with recently the cable has to make a sharp 90 degree bend upon entering the camera. Even the large Axis P3707-PE does this as well. Poor engineering IMO.

???

The turret and bullet style with whip form factor was prevalent in analog days. Maybe it is just easier (cheaper) to continue to use all the tooling and processes already in place and just change the guts of the camera. The "easier-to-waterproof" theory is solid. I wonder if there is a correlation between the competency of the installer and the price point of the camera as Dahua and Hikvision are largely used because they are low cost. In my experience, lower competency typically means more likeness of improper installation.
