For a customer we are designing a camera surveillance system which we will be mount a light towers. the current design is based on 4 hikvision DS-2CD2142 camera's, 2 Redwall SIP4010 5 detectors for detection. the whole system will be powerd by solar panels. now I am looking for industrial POE switches which will power the camera's and the detectors. so any suggestions for these using low power. also looking for a NVR which will send a message when an intruder is detected, and for local storage. 

As the system is being powered by solar panels it would be easy if the hardware (switch as well as NVR is powered by 12V) 

I am looking for suggestions for hardware or maybe someone who already has designed a system which has been tested and is working great.

 

many thanks and a Bon anja Nobo (happy new year)

A couple of things:

If you want alerts why not use high-end cameras with analytics and skip the Redwalls? 

How much power output do you have on your solar trailer and what do you have for batteries? 

The trick to reliable solar setups is to keep your current draw to a minimum. I would keep your hardware to a minimum to reduce current draw.

Also, keep in mind you don't need to use 12VDC with solar setups.  It is easy to configure 24VDC and 48VDC solar systems.

panels and batteries need to be calculated. during the day the camera's should work on the solar/ batteries. at night the generator for the light tower will be started. that s the reason that we would prefer 12VDC

You can always use a DC upconverter. Then you don't have to worry about limiting your choices based on voltage.

How do you plan on getting alerts? Wifi, Cell, wired....?

I'm assuming you are talking about the temporary light towers with the generator mounted on trailer. Depending on height, and quality of the equipment, it can be hard to to to get steady picture. Wind during the day and generator vibrations at night. Especially if you are viewing long distances. 

I would use Uniview cameras with edge storage. No NVR. A multiport POE injector. And mikrotik for your network if needed. Don't forget to protect line coming from batteries to your equipment.

Specifically the Uniview IPC744SR5-PF40(60)-32G. They use 12v and can tolerate 25% voltage drop or increase. 2D and 3D noise reduction, and can pan and tilt. Mounting multiple cameras on a telescoping pole and getting direction set is a pain if you can't climb it, or have a lift. If trailer moves you can make adjustments remotely.

and

Mikrotik Omnitik for your switch/wifi/wired connection. It's omni directional so if the trailer gets moved you don't have to adjust antenna if you use wifi. Has 5 ethernet ports so you wouldn't need a separate switch. Outdoor rated and works with 10-57 vDC 

You could do without the multiport POE injector and just do some creative cat5 wiring. Which would save on cost and possible place of failure.

Consider cameras with reliable, high capacity edge storage in lieu of NVR.

Why not charge a series of batteries with the generator during the night and power cameras off of the batteries during the day.
