Surveillance System Health Check in Houston, TX 77027
This ZIP holds three very different kinds of property within a few blocks of each other: post-war ranch houses on quiet interior streets, rows of three-storey townhomes sharing driveways, and small commercial suites along the Post Oak and Richmond corridors. A camera system serving each one fails in its own way, and the moment the failure matters is always the same — somebody asks you for a clip and you cannot produce it. Licensed, insured and 5.0-star rated, EVOTECH IT LLC has looked after Houston businesses and homeowners since roughly 2004.
One ZIP, three completely different inspections
What we examine depends far more on the building than on the brand of camera. A mid-century ranch, a stacked townhome and a leased retail suite present different cable routes, different blind spots and different reasons for the system to exist in the first place.
| Property | Usual system age & type | Where the inspection concentrates |
|---|---|---|
| Post-war ranch, Afton Oaks and the interior streets | Mixed generations; slab construction with a single accessible attic | Attic runs above the original footprint, sightlines under heavy tree cover, side-yard and rear approaches |
| Three-storey townhome rows | Newer, usually network cameras with a recorder at garage level | Shared driveway coverage, stair-core cable routes, equipment heat in the garage, roof-deck access points |
| Retail, restaurant and office suites near Post Oak | Whatever the previous tenant left, plus additions | Retention window, export capability, back-of-house doors, parking and staff viewing access |
On the residential side, the recurring problem is coverage drift: cameras aimed at a layout the property no longer has. Fences move, a driveway gate goes in, a garage is converted, a pool is built. The cameras keep pointing at the old arrangement. On the commercial side, the recurring problem is inheritance — a system left by a prior tenant, running under an account nobody can access, with a retention window nobody has ever measured.
The day someone asks you for footage
Almost every call we get about an existing system starts after an incident, not before one. A vehicle was broken into on a shared drive. A delivery went missing from a stoop. Something happened in a parking area behind a suite, and an officer, an adjuster or an attorney has asked for video.
At that moment, four things have to be simultaneously true, and any one of them will sink the request on its own:
- The event is still on the drive. If retention is six days and the request arrives on day nine, nothing else matters. Retention is the single most misunderstood number in surveillance, and adding cameras to an untouched recorder shortens it every time.
- A camera was actually covering that spot. Not the general area — the spot. Coverage is easy to overestimate from a live grid and easy to verify by standing in the place and watching the screen.
- The clock is right. Footage with a drifted timestamp invites a challenge to everything else in it. Recorders lose time quietly when time sync is not configured.
- The export plays somewhere else. Many systems export a wrapped file that needs the manufacturer’s own player. We produce a file in a common format that opens on an ordinary computer, and we verify it on one before leaving.
Stacked townhomes, party walls and a driveway you share
The townhome rows through Highland Village and the blocks feeding off West Alabama create a specific set of problems. Vertical distance is the first: a recorder at garage level, cameras three floors up, and stair cores that are frequently the only viable route between them. Where a builder left a usable chase, the work is straightforward. Where none exists, honest routing options are limited and we will say so rather than promise an invisible run that does not exist.
Heat is the second. Equipment placed in a garage in Houston lives somewhere between ambient outdoor conditions and worse. Recorders there run hot for months at a stretch and their drives show it in the error counters long before anyone notices a symptom.
The third is the shared driveway, which is where most incidents on these properties actually happen. A camera can watch the portion serving your own entrance; the geometry is tight and getting a usable angle on a vehicle without staring into a neighbour’s front door takes care. We check both the coverage and the aim, and where a camera is overreaching into a neighbouring unit we will recommend adjusting it. Party-wall construction also matters for wireless devices — a rear camera two units away from an access point can look fine on a good day and drop out on a busy one.
Small commercial systems off Post Oak and Richmond
For a shop, a clinic, a restaurant or an office suite, the health check is as much about process as hardware. Who among the staff can watch live, who can export, and does that list still match who works there? Access rights outlive employment routinely, and nobody audits them until there is a reason to.
We work through the points that tend to matter for a business: the entrance and the transaction area, the back-of-house and delivery doors that get propped open, the stock or supply room, and the parking that serves the suite. Cameras at a counter are often positioned to see the customer and not the till, or the reverse, when a claim usually needs both in one frame.
Leased space adds a layer. Building management may own the garage and common-area systems, penetrations through demising walls or the roof usually need landlord consent, and some of what a tenant wants is already covered by the building. We identify which is which before anything gets proposed, so you are not paying to duplicate coverage that exists.
One caution we always raise: recording audio is not the same as recording video in the eyes of the law, and the rules are not something a cabling contractor should be advising you on. If your system has microphones enabled, we will point it out and recommend you confirm your position with your own attorney.
You are left with the findings in writing, and any work you approve is priced item by item once it has been seen in person — never quoted blind over the phone. Book the free assessment on (832) 359-2425 or send us a message.

Frequently asked questions
An officer asked for footage and we could not give them anything. What usually goes wrong?
In our experience it is retention first and export second. The event had already been overwritten, or the file would only play in the manufacturer’s own software and could not be handed over in a usable form. Both are fixable in advance and neither is expensive to correct — but only if someone tests them before an incident rather than during one.
Our suite is leased. Can the system be checked without getting the landlord involved?
Inspecting, testing and adjusting equipment inside your own leased space is normally between you and your lease. The landlord enters the picture when work involves the structure, the roof, common areas or demising walls. We separate those clearly on the report so you know which items you can approve yourself and which need a conversation with building management.
Our townhome shares a driveway with three neighbours. Are we allowed to cover it?
Covering an area you have a legal right to use is generally accepted, but the practical aim matters as much as the principle. We position cameras to capture the approach and vehicles near your own entrance rather than framing a neighbour’s doorway, and we show you exactly what each camera sees before finalising anything. If your association has recorded rules on exterior equipment, check those first and we will work within them.
How much footage should a small business keep?
It depends on how quickly incidents surface in your operation — a retail theft is often known within a day, while a billing or liability dispute can appear weeks later. Your insurer may also have expectations worth asking about. The important step is measuring what you have now, because nearly everyone we visit has less than they assume, then setting the window on purpose.
Can you work on a system installed by a different company?
Yes. Most of what we inspect here was installed by someone else, and a fair amount of it is decent equipment that only needs correcting. We do not require you to replace working hardware to become a customer, and we will tell you when the sensible recommendation is to leave things exactly as they are.
