Hi All Happy new year

would like to install 1xuniview poe switch outside in a waterproof box just so i dont need to have 12 +cables coming inside house as restricted access

are there ways round to stop poe switch not working correctly due to uk weather heat or cold temps,i know box is waterproof

would like any sugestions if anyone has succesfully done this or is it you have to use a proper external poe switch

any info would be appreciative

 

If you have power you could fit a little temp controlled heater. Only ever fitted them inside

I have used different types , London tho , never had an issue except a cheaper version died after 10 years , used different types of IP box 

The storage & operating temperatures of the equipment will be stated on the data sheet.

Outdoor ones are at least triple the cost?

I have put internal equipment (AP) outside in an IP box at customers request, it lasted couple of years before it lost it's marbles.

I'd suggest that's a lot of equipment to go down if you have a failure and consider a redesign or using the proper stuff.

QFA id go for a camera heater in the WP Box just make sure its mounted properly not just sitting in the bottom of the box where it will melt through 

One practical middle ground is keeping the main switch indoors and only putting a small outdoor-rated PoE injector or a tiny industrial 2/4 port switch near the cameras, with a single data uplink back. That way a weather failure takes out less kit. If the UniView unit still has to live in the outdoor box, check the PoE budget at the high end of the temp range too. A lot of plastic switches brown out or drop ports when they cook in a sealed enclosure in summer sun.

Done plenty of these external cabinet setups over the years when pulling a dozen Cat5e/Cat6 runs back through cavity insulation or finished internal walls just isn't practical. You can certainly make a standard Uniview indoor switch work in an external enclosure, but there are a few practical rules you have to follow if you don't want it dying within 12 months:

1. Condensation is your biggest enemy, not rain.

A sealed IP66 box prevents water ingress from outside, but when the switch heats up during the day (especially under heavy PoE load when IR LEDs fire up at dusk) and ambient temperatures drop sharply at night, the air inside reaches dew point. Moisture condenses directly onto the cold circuit board and causes corrosion or micro-shorts. To prevent this:

- Fit a breathable IP67 pressure compensation vent (like a Gore-Tex membrane vent plug) on the lower side or bottom of the enclosure to equalize pressure without letting liquid water in.

- All cable entries MUST come through the bottom via properly sized compression stuffing glands (M16/M20). Never penetrate the top or sides of an outdoor box.

- Always form decent drip loops on every external cable before it enters the gland so driving rain runs down and drops off rather than tracking along the jacket into the fitting.

- Keep a couple of regenerative silica gel desiccant packs inside, zip-tied safely away from the power su

2. Thermal build-up in summer.

A Uniview switch running 12 PoE cameras is putting out significant thermal wattage inside a sealed plastic box. Standard commercial indoor switches are usually rated to 40°C or 45°C ambient. In midsummer on a south- or west-facing wall, direct solar radiation on an unvented polycarbonate box can easily push internal temps well past 55°C, causing thermal reboot loops and cooking the electrolytic capacitors.

- Mount the enclosure on a north-facing or shaded elevation if at all possible, tucked up tight under soffits/eaves.

- Oversize the box so there is plenty of internal air volume around the heatsinks and PSU rather than cramming it tig

3. Industrial/Hardened alternative.

If the location is exposed to full sun or freezing winter winds, it's worth considering an industrial DIN-rail PoE switch rated for wide temperature ranges (-40°C to +75°C). Hikvision, Dahua, and Planet make hardened unmanaged/managed switches that handle temperature swings effortlessly and use passive aluminum finned heat dissipation

4. Uplink and Surge Protection.

With 12 external camera cables running along exterior brickwork, any close atmospheric lightning discharge can induce spikes that travel straight into the switch and back down your link. Make sure your incoming uplink back into the house is solid Cat6 or, even better, if your Uniview model has an SFP slot, run a cheap pre-terminated external fibre patch back into the property. Fibre gives you complete optical galvanic isolation so an external surge can never jump into your internal network switch or router..ht.pply.
