Security & Surveillance
Buy and sell security cameras and recorders in Guatemala.
Most security kit in Guatemala ends up in one of three places: a Wi-Fi camera inside a home or shop, a wired set of cameras running back to one recorder, or a solar camera with a SIM card watching a farm gate where no power line or router reaches. Both new and pre-owned units change hands, along with video doorbells, recorders and the hard drives inside them. A used camera has usually spent its life on an outside wall rather than in a box, so the useful questions are how long it faced the weather and whether it lived through a lightning storm.
The cable, or the lack of one, decides the camera:
a Wi-Fi camera from EZVIZ, Imou or TP-Link Tapo needs only a socket and the router within reach, and records to a memory card or the cloud. It suits a room, a small shop or a single door. A wired set runs every camera back to one recorder, a DVR or an NVR, the setup for a house with several entrances or a business with a car park. A solar 4G camera carries its own panel, battery and SIM card, the usual answer for a cattle farm in Petén or a building plot outside Escuintla. Most solar units record only when the motion sensor trips, which suits a gate better than a till. With a video doorbell you answer the front gate from your phone. Unlike photo cameras or the action cameras under film cameras, all of these are built to watch one view for years.
Matching a camera to the recorder already on the wall:
this is where most used buys go wrong. Analog HD cameras send video down coaxial cable in one of three formats, TVI, CVI or AHD, and a Hikvision camera on an older Dahua DVR can give you a blank screen. Most recent recorders read all three plus a few IP channels, so read the label on your DVR before paying for cameras to add to it. IP cameras run on network cable to an NVR and are the sharper, dearer route. To recognise a face at the gate or read a plate, buy a sharper camera and mount it closer rather than wider. Plain infrared turns the night grey; colour-night models add a small light or a bigger sensor, so a red pickup stays red. Anything going outside should carry an IP66 rating or better.
Where a used solar camera saves money and a Wi-Fi camera does not:
a pan-and-tilt indoor Wi-Fi camera from a known brand costs around Q300 to Q450 new. At that price the second-hand saving is small, so buy one boxed and reset rather than freshly unscrewed from someone’s ceiling. Solar 4G cameras run from about Q800 for an unbranded twin-lens unit to around Q1,600 for a branded one, and here a used camera can take a real slice off the bill, provided the battery still lasts the night. Battery and panel are what age under the sun, so price a used one by how it performs after dark.
Lightning damage and the other faults in a used camera:
rainy-season storms are what finish off security gear in Guatemala. A surge travels down the cable from an outdoor camera and burns out a channel on the recorder, the power supply or the camera itself. Ask whether the system has taken a strike, and connect every camera you are buying to a recorder or the app before money changes hands. Then test it in the dark: cover the sensor, and the picture should flip to black and white with a faint red glow from the LEDs. Mist or droplets behind the lens mean the seal has failed, and a dome yellowed by years of sun blurs the night image. Unbranded boxes often claim a resolution the sensor cannot deliver; check it in the app. A hard drive pulled from a used DVR has been writing without a break, so count it as nearly spent.
The label on the back of each camera:
photograph it, because it gives the model and the video format, and someone driving in from Jutiapa or Mazatenango wants to know before setting off whether it will work with the recorder they already own. Say whether each camera was indoors or out, and list the adapters and brackets that go with it. For Wi-Fi models, mention that most join only the router’s 2.4 GHz band, and unlink the camera from your app account before the handover, or the buyer cannot add it to theirs. An office moving up to sharper cameras usually has a sound old set to pass on, and a short night clip from each camera, sent before the buyer makes the trip, is what sells it.
