The majority of Camera products fall into the "Type 1" column up above. Using less then 15 Watts of power
Type 2 PoE+ devices include outdoor housings such a the SHB-4300HP, X series PTZ cameras with out IR and some multi Sensor Camera products (PNM-9080VQ). Always check the spec sheet before starting the installation and hook up.
Type 3 and Type 4. are used in products such as the PNM-9081VQ, PNM-9320VQP and the XNP-6550RH. The H-PoE injector is normally included with the product.

It is important to note that constant reboot or no boot at all can be related to the device being under powered.
To verify, connect the camera separately with the correct PoE injector. In case of using a PoE switch with more PoE capabilities than needed, check the LLDP settings.
Devices that fall into the Type 3 or 4 power consumption range can reboot constantly if they are not on a properly rated injector. See information below:
PNM-9081 power requirements: Max. 33.6W (HPoE)
PNM-9320 power requirements: Max. 65W (HPoE)
XNP-6550RH power requirements: Max. 60W (HPoE)
The aforementioned devices ship with included injectors. It is NOT recommended to use another injector.

While H-POE injectors follow some standards, in many cases they are not backwards compatible
Also note that PoE standards allocate power at the switch and then the camera receives the power. For standard PoE, the camera can consume up to 12.95W, however the switch needs to allocate and consume up to 15.4W. For PoE+, this is 25.5W at the camera and 30W at the switch. This can lead to a PoE budget shortfall if the switch is fully loaded, depending on its' specifications. Always make sure the switch has enough power in its' budget.
Most switches use LLDP to determine of a device such as a camera requires more than 12.95W of power. Note that many managed switches may look like PoE+ and LLDP is enabled, however they often require additional configuration in the command line.
As an example, an HP/Aruba 2930F-48G-PoEP-4SFPP is capable of PoE+ and provides 370W of power. However a PNM-9080VQ was plugged in and it would show a PoE fault and the camera would never boot or display in Wisenet Device Manager.
Various configuration settings were adjusted in the web UI, to make sure LLDP was enabled, to allocate more power, etc., however the camera would not boot. Issuing the following commands resulted in the camera booting up correctly (in this case ports 1-48).
int 1-48 poe-lldp-detect enabled
You can also use the following commands to view the LLDP configuration including how much power the camera is requesting (in this case port 9).
show lldp info local-device 9
show lldp info remote-device 9
Note that each brand switch will be different, but this is very common. If a Cisco switch is used, you will need to disable their proprietary CDP protocol and enable the industry standard LLDP.
